Introduction

Given that we’ve got such a strong following from the Miata fan base, we’ve had many requests for articles where we round-up the best Miata upgrades available on the market.

With so many different guides, we’ve built up an impressively comprehensive selection, and we’ve created this article to get them all in one place.

We, therefore, declare this – the Ultimate Miata Mods guide!

After its unveiling at the 1989 Chicago Auto Show, the Miata immediately changed the two-seater roadster game with the NA’s introduction.

The Miata’s fresh-out-the-showroom price tag of just $14,000 would soon make it a cult classic among petrolheads.

Best known for its handling rather than power abilities, this perfectly-refined package was about the closest you could get to having a road-legal go-kart.

The first version featured a 115 hp 1.6-liter engine, and Mazda would later introduce the 1.8L variant, capable of a more-impressive 133 hp.

For the 1998 model year, the second-generation NB reached the market. Although enthusiasts were disappointed to see the pop-up headlamps’ exclusion alongside the modernized design, however, it thankfully came with a power upgrade providing 140 hp.

When the facelift arrived in 2001, US Miata’s received 143 hp, while Japan, UK, and Australian Eunos/MX5 models were treated to 152 hp.

Power increases continued with the limited edition models. The MX-5 SP was limited to just 100 models, which reached 200 hp for the first time, proving that the Miata undoubtedly had more power potential in-store.

This turbocharged variant is the highest-powered Miata (well, MX5) that Mazda has released in the factory form in the present day.

There’s no secret that we love the humble two-seater roadster that provides top-down, drifty goodness along with an incredible price tag, making it a perfect choice for those getting started with drifting.

One of the great things about Miata’s is that they’ve continued being sold from the early 90s to the present day, meaning that there are opportunities to pick up some real bargains at the older end of the market.

Alternatively, if you’re looking for some modern-day luxuries, then you’re still able to head to the local Mazda showroom to get your hands on a brand-new Miata.

Since the Miata has one of the largest aftermarket selections out there, from NA to ND, they provide the perfect platform for tuning, and with the right upgrades, your humble two-seater could soon be battling it out with the big boys.

With some simple upgrades that we’ve listed in this guide, your Miata is easily capable of being transformed into something special.

Whether you’re just looking to replace your tired old battery, upgrade your headlights that resemble candles in the night, or go all-out with a crazy-powered turbo upgrade, we’ve covered it all.

As tuners, let’s face it - we know that the Miata has so much more potential waiting to be unlocked.

If you’ve not yet purchased a Miata and you’re considering whether it’ll be the ideal choice for you, make sure you check out our Miata vs BRZ article, where we put the two impressive contenders head-to-head.

For now, let’s take a look at the best upgrades to get the most out of your Miata!

Best Miata Batteries

Car batteries usually are one of the most straightforward parts when it comes to routine maintenance.

Given the nature of Miatas, they’re somewhat of a headache compared to your typical daily driver.

As a Miata owner, you’re likely to be already aware that they’re fantastic when it comes to chewing through batteries quicker than most cars on the road.

Given the age of the NA and NB models, they’re likely to have already been replaced, and if not, we’re certainly not surprised that they’re reaching the end of their lifespan.

Since some NA’s are now celebrating their thirtieth birthdays, it’ll be a real cause for celebration if your battery has somehow survived along the way.

If you’re stumped when it comes to locating your Miata battery, Mazda designed the NA and NB generations to run the battery in the car’s trunk, rather than under the hood, to provide optimal handling performance.

Heat can become a big issue for batteries, especially on a forced induction setup, where temperatures will be far higher than your typical naturally aspirated setup, which is worth thinking about for NC/ND owners.

When it comes to finding the ideal battery for your Miata, ensure you opt for an AGM (Absorbed Glass Mat) battery, as these won’t spill acid into your trunk over time, unlike other batteries.

Cheap batteries can be tempting in budget cars. However, given Miata batteries’ location, we certainly don’t recommend going down the cheap lawnmower/tractor battery route like some ‘enthusiasts’ will advise online.

With the incorrect fitment, cheap car batteries can become extremely dangerous, and that’s certainly not worth saving a few bucks on in our minds.

Let’s take a look at our recommended batteries for your Miata.

Our NC/ND Battery runner-up was the Duralast Gold.

If none of these batteries tick the right boxes for your needs, then make sure you head over to our Miata Battery guide, where we provide a vast selection to choose from.

Best Miata Coilovers

Since the Miata has one of the largest aftermarket selections out there, prepare yourself to be spoilt for suspension choice. Some owners might tell you not to bother buying a fancy suspension kit and chop your springs, but we all know this is far from the perfect solution.

A highly-regarded coilover kit will completely transform this two-seater roadster’s handling, and the Miata provides the ultimate platform to get the most out of a coilover setup.

Coilovers help you to achieve the perfect fitment and stance while giving you a ride range of adjustability, whether you’re after a soft, lowered ride or a stiff track-clinging setup.

Drifted Miata NA/NB Coilover Winner

If they’re out of your price bracket, consider opting for the Tein Flex Z for a great low-priced all-rounder.

Construction type: Twin-tube
Spring rate front: 230 (lbs/in)
Spring rate rear: Progressive

KW brings their competitor for the Ohlins Road & Track. This is KW’s big daddy kit, which certainly lives up to expectations and includes full 3-way adjustment and corrosion protection. These are unsurprisingly one of the most popular coilover choices on the market.

We know that it’s always a personal choice as to whether you go for these or the Ohlins Road & Track. If you like the Ohlins, they’re an incredible choice too. If you’re after a stiffer ride, then maybe consider those instead.

Drifted Miata ND Coilover Winner

Levels of damping adjustment: 20
Construction type: Monotube
Spring rate front: 572 lbs/in

Purchase link: Ohlins Road & Track Miata ND Coilovers

It’s the Ohlins Road & Track that we once again provided the best all-around offering for ND Miata owners.

They were the most featured coilover kit in our guide, and quite rightly so. These suspension giants are certainly not to be dismissed if you’re looking for a serious setup.

Quality comes at a price, and Miata Ohlins owners have been delighted with this setup for many years. It features strong corrosion protection which shows that they are built to last. The DFV technology certainly sets these apart from the lower-priced competition.

For our runner-up, we would go with the tried and tested HKS Hipermax GT IV. These are undoubtedly a fantastic lower-price choice for those who aren’t too serious about track times.

If none of these coilover kits tick the right boxes for your needs, then make sure you head over to our Miata Coilover guide, where we provide a huge selection to choose from.

Best Miata Cold Air Intakes

Once you’ve had your Miata for a while and enjoyed the fun that top-down motoring and drifting has to offer, you’ll probably be looking to carry out some upgrades.

If you’re looking to improve the sound of your Miata, perhaps add some engine bay bling and allow it to breathe a little more freely, there’s the option of upgrading your cold air intake.

CAI’s are one of the most popular off-the-shelf modifications for the Miata. Although the manufacturers’ power claims are often somewhat inflated, they can still be a worthwhile upgrade to consider.

It’s always important to get your engine breathing as freely as possible, and there’s no better way of doing so than relocating your air filter to inhale the coldest air possible.

As you’ve probably guessed, an engine bay gets pretty hot, especially when pushing your Miata to its limits. Hence, the job of a CAI is to provide additional cooling to the engine to improve its efficiency.

When a CAI is coupled with an exhaust, this is when you not only get the optimum airflow, but you’ll also provide a much-improved soundtrack, which you can enjoy to its maximum potential with the roof down.

Drifted Miata NA Cold Air Intake Winner

Thankfully, due to their simplicity and gaining a considerable aftermarket following over the years, there’s a vast array of aftermarket NA cold air intakes to tickle your fancy. However, this kit was the particular stand-out for us.

Randall Cowl Intake Duct

Manufacturer: Randall
Fitment: 89-97 1.6 & 1.8L Mazda Miata NA
Value for money: ?????
Purchase link: Discontinued

Are you looking to add some reasonably-priced carbon fiber bling to your Miata’s engine bay? Look no further!

Due to its imaginative design, the Randall Cowl Intake Duct often takes the crown as the best choice for those of you that are keen to achieve the maximum performance from your NA Miata.

Taking advantage of its unique design, the Randal Cowl Intake pulls the cool, high-pressure air from the Miata’s cowl area, unlike most CAI’s, which extract air from the front of the bay. Randall’s design is hugely beneficial in hot-weather scenarios and has repeatedly proven to keep engine temps down.

Flyin’ Miata claims that they achieved a 5 HP gain with this method in a real-world test scenario with a closed hood. They also state that they noticed significantly improved intake growl under load, too.

The downside of the Randall kit is that you’ll need to cut a hole above the firewall, which may not be allowed in some competitions, so it’s certainly worth doing your homework if you’re likely to have challenging race restrictions.

Due to its popularity and simplicity, a common trend among the Miata community is to build a DIY Randall Cowl. If you’re doing a budget build, and aren’t looking for engine bay bling this could be a perfect alternative.

The Randall cowl provides a simple yet extremely effective design with a fantastic looking carbon fiber snorkel. For those of you looking for maximum power gains without needing to worry about competition legislation, this is an excellent choice.

If you’re looking to compete in your Miata and can’t cut into the firewall or don’t like the idea of doing so, we’d recommend checking out our runner up, the Apexi Power Intake.

Drifted Miata NB Cold Air Intake Winner

Although the NA and NB share many similarities, the CAI choices on the market are entirely different, and this kit was a clear winner for the NB.

K&N Typhoon Cold Air Intake Kit

Manufacturer: K&N
Fitment: 99-05 Miata NB 1.8L
Value for money: ?????
Purchase link: Buy your K&N Typhoon Cold Air Intake Kit here

This kit adds a premium-sounding intense, deep growl to your Miata and features the typically excellent build quality that you’d expect from K&N.

If you’re after engine bay bling, then this is one of the best looking kits out there. While there are dyno claims of 3-4 HP power increases, this is much of a muchness when compared to its rivals.

Overall, this provides significantly improved airflow, a small power increase, great looks, quality, and a reasonable price.

Many owners say they would happily repurchase it purely based on the intoxicating sound.

Drifted Miata NC Cold Air Intake Winner

Although there are fewer options for NC compared to the previous generations, there are still some fantastic choices to be had.

One of NC’s main positives is the ease of access to airflow from behind the front bumper, where most kits remained within the bay for NA and NB’s.

The improved location allows for cooler air to reach the engine, but the downside is that it requires longer piping.

AEM Cold Air Intake

Manufacturer: AEM
Fitment: 05-15 Mazda Miata NC 2.0L
Value for money: ?????
Purchase link: Buy your AEM Cold Air Intake for 06-09 models here |
Buy your AEM Cold Air Intake for 2010+ models here

This kit positions the filter in the lower part of the front bumper, where it’s capable of extracting the maximum possible airflow.

We think that this is the best thought-through NC kit on the market, and it comes at a reasonable price, too.

Although we somehow doubt their claims of 10 HP gains, we’re sure that its ideal location will provide some much-needed cooling for your NC’s engine.

Drifted Miata ND Cold Air Intake Winner

Over its lifetime, Mazda has continued to improve its intakes, and you are going to struggle to see significant improvements over the well-refined stock unit on the ND.

You can still enhance the sound and add a unique touch to your engine bay with these great CAI choices.

Mishimoto Performance Air Intake

Manufacturer: Mishimoto
Fitment: 15+ Mazda Miata ND 2.0L
Value for money: ?????
Purchase link: Buy your Mishimoto Performance Air Intake here

Despite coming in cheaper than AEM, Mishimoto has provided a fully enclosed powder-coated airbox for keeping the temperatures as low as possible.

Although they don’t make any excessive power figure claims, they say it may help you achieve up to 3 HP; you’ll undoubtedly notice some improvements from a sound perspective.

Mishimoto is happy to stand by their quality products, which is why they offer a lifetime warranty for this fantastic piece of kit, which comes highly recommended.

Overall, this is a fantastic piece of kit, especially for the price, which we’re confident won’t leave you disappointed (unless you have unrealistic power expectations, of course!)

Best Miata Exhausts

As fantastic as this tiny sports car is, many owners are left underwhelmed by the stock power and sound.

Thankfully, an exhaust upgrade will help you squeeze some vital horses from under the hood and provide you with a much more pleasant soundtrack in the process!

Drifted Miata NA Exhaust Winner

APEXi N1 EVO Exhaust System

Manufacturer: APEXi
Internal pipe diameter: 50-60mm (2-2.3″)
Tailpipe configuration: 90mm (3.5″) tip
Primary exhaust system material: Stainless Steel
Value for money: ?????
Purchase link: Buy your APEXi N1 EVO exhaust here

This exhaust is the perfect all-rounder - combining great looks, excellent quality, and a sexy tone.

They say that quality comes at a price and the daddy of NA exhausts proves that. This full stainless cat-back system brings APEXi’s legendary quality and fitment to make your NA look better than ever.

The exhaust won’t drone on long journeys like cheaper offerings, yet it roars to life when you hit the throttle on the canyon runs.

There are certainly cheaper alternatives out there, and if you don’t mind your car being louder and drone noise won’t bother you, make sure you take a look at those too.

Drifted Miata NB Exhaust Winner

ARK DT-S Exhaust System

Manufacturer: ARK
Internal pipe diameter: 63.5mm (2.5″)
Tailpipe configuration: 90mm (3.5″) tip
Primary exhaust system material: Stainless Steel
Value for money: ?????

Despite having a higher price tag, it’s easy to see why the DT-S is so popular with Miata owners. It boasts a pure, deep exhaust note (which isn’t overly loud) alongside a well-crafted, free-flowing design.

Combine this with the great looks and typically fantastic quality from ARK, and there’s no doubt this exhaust is a great all-rounder. ARK also offers numerous tips, such as polished, burnt, and techno, depending on your preference!

ARK’s popular offering boasts a pure, deep exhaust note while still maintaining a subtle noise level.

Combine this with ARK’s usual high-quality and a selection of tips, it’s undoubtedly a great choice. If you’re after something a little cheaper, we recommend looking at the Megan Racing alternative.

Drifted Miata NC Exhaust Winner

Tomei Expreme Titanium Exhaust System

Manufacturer: Tomei
Internal pipe diameter: 60mm (2.3″)
Tailpipe configuration: 90mm (3.5″) tip
Primary exhaust system material: Titanium
Value for money: ?????
Purchase link: Buy your Tomei Expreme Titanium NC muffler at Enjuku Racing

It may seem like a bargain, but this incredible offering from the legendary exhaust creators will come at a price to your eardrums.

This system is certainly not quiet, but it’s an absolute work of art and a thing of beauty. If you’re building a serious weight-shedding track car, this is the exhaust for you. With a weight loss of 21lbs in this muffler alone, the full exhaust system takes off an insane 16kg total weight from the stock exhaust.

If you only want the best for your NC, combine it with their matching straight pipe and manifold for the ultimate performance, looks, and sound. Admittedly, this may also cause a beating to your wallet too, but we think it’ll be worth it!

We don’t recommend it for street use, but if you’re planning to head to the track and cut down those valuable lap times, this is undoubtedly the choice for you.

Make sure you check out ISR Performance‘s offering if you’re upgrading your street-car.

Drifted Miata ND Exhaust Winner

Tailpipe configuration: Twin 82mm (3.25″) tips
Primary exhaust system material: Stainless Steel

Featuring the typically impressive welds and design we’ve come to expect from them over the years, this exhaust certainly doesn’t disappoint. It delivers a clean and subtle yet deep rumble, which opens up perfectly when you step on the gas. If you want to get the best out of it, make sure you check out their full exhaust system.

If we’ve not provided you with the perfect exhaust for your Miata with this selection, make sure you head over to our Miata Exhaust guide, where you’ll find a wide selection to choose from.

Best Miata Racing Seats

Miata seats, particularly from the earlier generations, seem to have earned themselves a love/hate relationship among enthusiasts.

Some will argue that the Miata’s OEM seats are fantastic, and they’ve even become a popular ‘upgrade’ for vintage car owners that are looking for a little more comfort or support on a budget.

On the other hand, other owners believe that they’re too hard, too flat, and don’t feature anywhere near enough support.

Either way, I think it’s safe to say that although the stock seats are adequate for many purposes, there’s no question that they’re deteriorating with age, and let’s face it, there are better alternatives out there, whatever your needs may be.

Some owners look to aftermarket seats for styling purposes. After all, the seats in a Miata are far more visible than most cars, especially when it comes to a roof-down blast.

Other enthusiasts may be looking to find the ultimate racing seats, which will provide adequate support, ensuring they don’t end up flying over to the passenger side when they initiate their first drift, or flinging them around the car on their first grip day.

Although some owners opt for upgrading their OEM seats with the likes of the alternatives found in the Lotus Elise, this can soon end up becoming costly, and you’re likely to be left with old, worn seats, which are crying out for a refurb.

Not to mention that their increasing popularity and rarity are making them harder than ever to come by with a reasonable price-tag.

However, if you want to keep life simple, then there’s a vast array of incredible brand new aftermarket seats waiting on the shelf ready to be fitted into your Miata.

When looking for the perfect seats for your Miata, you’ll ideally want to find seats with around a 19.5-inch base and 21-inch shoulder width. However, the shoulder width will depend on the height where the seat widens.

Typically, the maximum base width you’ll be able to consider will be around 22-inches, with a shoulder width limit of 24-inches.

With all things considered, we found these seats to be the perfect choice for Miata owners:

Bride A.i.R.

Manufacturer: Bride
Base width: 18.5″
Shoulder width: 22″
Value for money: ?????
Purchase link: Buy your black Bride A.i.R. seats here | Buy your red Bride A.i.R. seats here

Bride’s A.i.R. series is the latest in Bride’s revolutionary line of seats, which could quite possibly be the ultimate seat for Miata owners.

Specially designed with two-seaters in mind, the A.i.R. series utilizes Bride’s LOWMAX system to ensure the lowest possible seating position, allowing zero offset with the floor pan.

The new lower-angled side bolsters make getting in and out of the seats far more convenient than traditional buckets. Yet, the modern design also ensures that you still receive significant hip support when driving.

Stylish, unique, and weighing in at just 6.8kg per seat, this brand new offering from JDM legends Bride could well be the perfect Miata solution.

Although the A.i.R. isn’t the usual, common choice, we feel that’s because they’re one of Bride’s latest releases and haven’t yet had time to settle into the deserved spot in their unique market.

They’ve been designed with two-seater convertible sports cars in mind, and they look stunning in any generation of Miata.

Bride intentionally aimed at having minimal head-rest and shoulder bolsters to reduce drag when driving with the top down.

Not only that, but they’ve also made the seats as narrow as possible to allow for maximum clearance within the tight Miata interiors. We have no doubt they designed these with the likes of the Miata owner in mind.

If these are out of your price range, we highly recommend checking out the insanely reasonably-priced Corbeau Forza, which will be perfect for a lower-budget build.

On the other hand, if you’ve got some cash to splash and you’re looking for a luxurious, premium seat, then look no further than the Sparco SPX

We understand that the A.i.R. won’t be ideal for everyone’s taste and budget, but you really can’t go wrong with any of the five-star options in our Best Miata Seats guide.

Best Miata Supercharger Kits

Although the Miata provides the perfect opportunity in the twisties for low-budget fun, it can sometimes lack the necessary grunt when it comes to the straights, whether at the track or when you’re carving the canyons.

Thankfully, the aftermarket tuning scene has stepped in to provide a vast range of aftermarket supercharger kits to suit the power goals you’ve been craving.

Thanks to the impressively low weight of these cars, forced induction can completely revolutionize your Miata and provide you with the perfect opportunity to cause some real upsets, even without the need for a huge budget.

Best Miata Turbo Kits

What if you’re looking for the crazy power delivery that only a turbocharger can provide? We’ve got you covered.

Be warned; this will turn your sensible daily driver into a weapon that’ll leave you grinning from ear to ear every time you turn the key in the ignition!

Miata’s are one of the most common cars for carrying out DIY turbo modifications, and there’s a vast wealth of information spread out across the internet for building a DIY turbo kit, whether you’re looking for enormous power or building on a budget.

However, we’ve noticed that there are very few guides that put the off-the-shelf turbo kits side by side to help you pick the perfect choice for your needs.

Sure, a DIY kit may save you a few bucks, but if you haven’t got several spare weeks, or you’re not an expert when it comes to fabrication and technical knowledge, we’d personally recommend paying the extra bucks for a tried-and-tested method.

Not only this, but you can ensure that if you get stuck, the support from these companies will be second-to-none, rather than posting up on an owners club in the hope that someone may have a solution to your custom-based issue.

So, let’s take a look at the best off-the-shelf turbo kits that are available for each Miata generation:

Drifted Miata NA/NB Turbo Kit Winner

This setup provides everything you’re going to need in a convenient, perfected package. Think of this as the ultimate NA/NB ‘bolt-on and drive away kit’, supplying everything you’re going to need to have your boosted Miata up-and-running.

Any searches online will bring up heaps of delighted customers that have been running this kit for thousands of miles with perfect reliability.

One of the main additional benefits of this kit is that it’s the only NA/NB option that is CARB legal. This means it’s emissions legal in ANY state in the US. Pretty neat, huh?!

In our opinion, there’s simply no better choice for those of you looking for a quick, easy, and perfected off-the-shelf kit for your NA/NB Miata.

Despite the NC being an excellent potential base for a product, there’s not a wide range of variety on the market when it comes to aftermarket turbo kits.

Fab9 Tuning is one of the companies that opted to fill the gap in the market, and they’ve done so in style.

This kit comes with an exceptional reputation from many delighted owners and should certainly be a consideration for any NC owners considering opting for a turbo setup.

Best Miata Wheels

There are many advantages to replacing the wheels on your Mazda Miata. Although looks are important, they aren’t the only thing to consider, depending on what your intentions are with your Miata build.

Most rims on the market provide significant weight reductions over the stock wheels, some more so than others, and maintaining or even shedding weight from the already-light chassis offers the perfect solution when it comes to getting the most out of your Miata.

The OEM NA/NB Mazda Miata typical wheel weight ranges between 10-15lbs per corner.

For the NC/ND models, that goes up to nearer 20lbs.

Alongside the acceleration advantages from the potential weight saving, having a wider track will also improve the car’s handling, which means it’ll become quicker in both a straight line and the twisties.

Once you’ve got the acceleration and handling improved, you can refine the handling even further by opting for wide wheels, which will allow for more grip and traction on the road.

However, if you happen to go too wide on your tire width on a stock Miata, you’ll likely gain weight and potentially slow down your acceleration times, and we certainly don’t want that!

For drifting or racing, you’re going to want lightweight rims.

However, if you’re cruising the streets without performance in mind, weight might not be a huge concern, in which case you can opt for some of the super-wide options out there along with a fender kit.

We’ve not only chosen some of our favorite rims, but we’re featuring what owners have opted for as their ultimate Miata choice.

Drifted Miata Wheel Winner

Enkei RPF1

Whether you own an NA, NB, NC, or ND, Enkei has provided a wide range of fitments to ensure they fit every Miata family variation.

In our mind, there’s no question that the RPF1’s are the finest all-rounder available to Miata owners.

They might not be the cheapest, but we feel affordable and undoubtedly worth the money.

They’re not only lightweight but also incredibly robust and will withstand far more stress than most of the budget alternatives out there when it comes to hitting up the track, or the street, in style.

Drifted Miata Wheel Runner-Up

Advanti Racing Storm S1

The Advanti Storm S1 rim has been continually growing in popularity, and it’s easy to see why.

Available at a fraction of the cost of the Enkei RPF1, these impressive wheels have implemented Flow Forming Technology to provide similar weight at a fraction of the price.

There’s a wide range to choose from to find the perfect fit for your Miata.

Drifted Miata Wheel Budget Choice

Konig Hypergram

Providing exceptional value for money to the market, the Konig Hypergra wheels have well and truly earned their spot as our guide’s budget choice.

Don’t make the mistake of thinking that budget means cheap, nasty, and heavy, as the Hypergrams wheels are the complete opposite.

Once again, integrating the exceptional Flow Forming Technology, these lightweight rims are superior in the weight department to some of the premium offerings out there, and you’ll get Konig’s usual quality to match.

A fantastic choice for the money, and it’s easy to see why it’s such a popular wheel choice within the Miata community.

If you’re not convinced by our favorites, understand entirely – looks are in the eye of the beholder, after all! We’ve got plenty more to choose from in our Miata Wheel guide.

Conclusion

We hope we’ve provided you with the perfect choices when it comes to choosing the best upgrades for your Miata, whatever your needs and budget may be.

We’ve spent countless days combining our extensive Miata knowledge alongside the opinions of our fans, Miata enthusiasts, forums, and social media channels online to bring you what we feel are the ultimate picks.
