Keeping you up to date with the latest CorkSport Mazdaspeed news!
The wait is over, better handling for your GEN4 Mazda is here! Introducing the CorkSport Rear Sway Bar for 2019+ Mazda 3, 2020+ Mazda CX-30! Reduce understeer, improve your handling feel, and reduce body roll by adding the CS sway bar to your Mazda. We went through multiple designs to ensure the right stiffness to get the handling gains you want, without excess oversteer or effects on ride quality. Read on for full details!
If you are a car enthusiast, own a new Mazda utilizing the awesome SkyActiv-G Turbo Engine, and have been searching the internet for performance parts then you probably know that CorkSport has been deep in development for this new Mazda platform. Specifically, CorkSport has been working on the last piece of the intake system puzzle, the Turbo Inlet Pipe.
This is the black plastic “tube/pipe” that connects the Short Ram Intake System to the turbocharger inlet. While the SRI System adds some great turbo noises and power gains to the Sky-Activ Turbo, there is still more opportunity for additional performance and sound improvements. This is where the new CorkSport Turbo Inlet Pipe steps in.
Enjoying your 4th GEN Mazda 3 but wanting to change up the look? Introducing the CorkSport Performance Spoiler for 2019+ Mazda 3 Hatchback. We went for an OEM+ design that incorporates the great fitment and lines of the OEM aero kit spoiler but in a much more aggressive package. Taller, longer, and with an upturned rear edge, the CS spoiler add some much needed sportiness to the look of your 3. Available in multiple finishes to suit your budget and build, the CS spoiler is a great next mod for your build! Read on for more details and check out the product listing here to purchase.
We like the OEM spoiler but were disappointed at how insignificant it looks when installed, especially when paired with the fairly aggressive OEM front lip & rest of the aero kit. The CorkSport Spoiler takes design cues from the OEM aero kit spoiler however, the design is unique to CorkSport. We started from scratch and polled the community for design opinions before settling on a final design that is both higher off of the rear hatch than OEM and extends further rearward than OEM. The design is finished off with an upturned rear edge for a great “duckbill” style look which is aggressive without being too much. You’ll be turning heads, especially when paired with CorkSport Lowering Springs and a nice set of wheels!
Fitment was equally important as aesthetics when we designed the CS spoiler. We 3D scanned an OEM aero kit wing to get the exact mounting surfaces and edge profiles so that the CS version fits just as good as OEM. We use the same mounting locations as OEM as well. This means no drilling if you’re switching from OEM aero kit to CorkSport spoiler. If you do not have the OEM spoiler you do have to do some drilling, however, Mazda pre-marks the holes for a relatively easy install! By using the same mounting locations and more adhesive mounting tape than OEM, you can be sure your CorkSport spoiler won’t be going anywhere!
The CorkSport Mazda 3 spoiler is offered in three finishes so you can choose what is best for your build. Each option uses a fiberglass base with different top layers. Regular woven carbon fiber, forged carbon fiber, and basic black fiberglass are each available. The carbon fiber options feature a UV resistant epoxy top coat for great protection from the elements and a mirror like finish. The full fiberglass option comes in a satin black coat with some light scratches and will require some finishing. We recommend some finish sanding and a final layer of paint or wrap. The shape is the same for each unit however the purchase price varies so you can really choose the best option for your build & budget.
Finally, each CorkSport spoiler comes with all the hardware and accessories needed for installation. This includes mounting bolts, washers, mounting tape, and rubber washers for waterproofing. We even include new replacement OEM Mazda clips that almost always break with removing the upper trim panel on the hatch! All of this comes with full color install instructions and great customer service & support!
So if you’re ready to take your GEN4 build to the next level, check out the CorkSport Performance Spoiler for 2019+ Mazda3. We think it’s what the OEM spoiler should’ve been and you will not be disappointed! Don’t be shy to contact us with any questions!

Are you looking for an exterior mod that will freshen up the look of your first gen Mazdaspeed 3? Well if that’s the case then the Carbon Fiber Spoiler is the perfect part to install on your build. The Carbon Fiber Spoiler retains the OEM look with the much-appreciated addition of carbon fiber. Keep on reading below for more info on the carbon spoiler.
Since the Carbon Fiber spoiler is based off of the factory Mazda piece, installation is a breeze and requires no drilling or other modifications to the hatch. We have also pinned the third brake light so that it can reuse the OEM connector with no modification to the harness needed! The Carbon Spoiler also comes with all the necessary hardware to install the spoiler so you can be back on the road in no time. Fitment with other add-on parts such as spoiler extensions or gurney flaps should work with the OEM style shape, however, we have not tested it. The same goes for GEN1 Mazda 3, the CF spoiler should fit, however, you may have a different 3rd brake light setup and/or have additional holes from the smaller Mazda 3 spoiler
The Mazdaspeed Spoiler features a fiberglass base that is then topped off with a layer of carbon fiber on the top side of the spoiler. The underside of the spoiler is finished in gloss black and the whole thing is then coated with a UV-resistant epoxy resin to provide a mirror-like finish and the necessary protection from the elements. The two halves come together on the rear edge so there is a small seam, however, once installed, the seam all but disappears!
If the CS Carbon Fiber Spoiler is a mod that you would like to add to your build, then head over and check out the product page for additional photos! Also, feel free to contact us with any questions you might have.

The time has FINALLY come…years in the making! Thousands of hours have gone into the development of the only turnkey turbocharger kit for the Mazda 3. From air filter to downpipe and everything in between, the Turbo Kit for the 3rd generation Mazda 3 has finally come full circle and IT IS AWESOME!
Are you ready for an extra 115-125whp and 80-90wtq?
Many have asked “Why So Long?” and the truth is because we, the Team at CorkSport, would not allow ourselves to put out a kit that was not complete, was not turnkey, and was not proven to be daily and track ready. We have put thousands of miles on out test vehicles; both on the track…
And on the street…
So what is involved in developing a turnkey turbo kit for the originally naturally aspirated vehicle? Well, basically everything., Let’s get more into the details.
The turbo is a big one, spec’ing the size, style, & location is a significant aspect of the kit. In fact, we tested multiple sizes before deciding on the turbo for the kit. Finding the right balance of spool/response, boost operating pressure, and even sound was a consideration (hey we all like turbo noises right?) With that we are using an MHI based turbo that utilizes journal bearings and liquid cooled CHRA. Our current CST4 and CST5 turbochargers for the Mazdaspeed use the same MHI CHRA and have proven very reliable and robust.
The turbo in the Mazda 3 Kit is also uniquely a twin-scroll internally wastegated design. This helped with spool and response while using a larger wheel spec and the internal wastegate keeps overall costs down and quiet.
On each end of the turbo is the next major design challenge, the exhaust manifold and downpipe. Now, in most kits you would expect to see a fabricated manifold and downpipe. While that is not necessarily bad, there are more robust methods of manufacturing that can perform equal if not better. This method is casting, which is what we have done. The exhaust manifold is a cast stainless steel 304 twin-scroll design. This one-piece design means there are no welds, seams or connections that could fail and the wall thickness is thicker (5mm vs 3mm) when compared to standard fabricated manifolds.
The downpipe utilizes a cast bellmouth which is then welded to a 3-inch pipe and flex section. This downpipe then aligns with the OEM location exhaust so you can run a stock exhaust (don’t be silly though), a 60mm or 80mm exhaust with your turbo kit.
Since we are talking about the cat-back exhaust let us just say that for peak performance you will want the 80mm exhaust system on your Mazda 3. Moving down to the 60mm you will lose a tad bit of power. Note: In the instructions there are specific boost controller settings for each exhaust setup.
Now we have all the plumbing to get that boost from the turbo to the engine. When we approached this we wanted a kit that was stupidly simple and clean in the engine bay. The result was ONLY two pieces of charge piping and four pieces of charge piping silicone. This keeps the possible boost leaks to a minimum and the install process simple. With that being said, the “hotside” charge piping runs alongside the passenger side of the engine and the “coldside” runs right up from the intercooler and to the throttle body.
To complete the charge air system we have the intercooler. The intercooler is no off-the-shelf generic unit either, we custom designed the cast aluminum endtanks to fit with the Mazda 3 chassis WITHOUT cutting and maximized the intercooler size to perform great with the power goals of the Turbo Kit, again without cutting your Mazda 3. Good to 400 horsepower, the intercooler will easily cover the current power and future growth in power of the kit for quite some time.
Because of the custom fit and lack of cutting, the intercooler nearly disappears in the OEM bumper for a stealth look. The black finish performs and looks great through the seasons. If you want to a customized stand out look, you could paint the core a nice bright silver finish without issue.
So we’ve covered the obvious parts of a “turbo kit” but what makes the kit turnkey? It’s the little things, like clamps, hardware, and connection like the turbo cooling, and the oil feed and oil drain. For the oil feed and drain we have provided perfect length stainless steel braided lines and all the needed fittings. The oil drain is extra special because on a non-factory turbo there is NO spot for the oil drain in the engine. So install of requiring you to drill a hole in your oil pan and risk causing a leak, we do the work for you with a new OEM oil pan. We complete the drilling, the drain fitting install and sealing. All you have to do is remove your oil pan and install the new oil pan with the drain fitting installed.
Lastly, to make all the big parts fit in the engine bay and look good, we had to create some clearance for the intake by using a smaller AGM battery vs the huge lead acid battery. To do that we designed a SS battery mount and ECU relocation bracket along with a new 550ca/450cca AGM motorsport battery which is included for ground shipping customers. If you are international and the kit has to air ship to you then you will need to source the battery locally.
Now to really round off the “turnkey” aspect of the kit we have the boost control system which includes a TurboSmart E-Boost controller which allows us to dictate and control the boost curve for optimal power delivery and reliability. No manual boost controller here that does whatever it wants. To monitor boost we provide a CorkSport boost gauge that you can mount anywhere inside the cabin for easy readout. Also, with a boosted setup and high compression ratio a set of 1-step colder spark plugs are required for safe operation, these are also included and future replacements can be purchased at CorkSport.
Most important is the tuning, and this is where we have spent hundreds of hours alone getting the car to perform consistently and reliably for you. The turbo kit had to feel fun, fast, and repeatable all while being safe to drive every day on a stock engine. With the CorkSport Turbo Kit, you will get a calibration license to your vehicle and Mazdaedit license designed to operate on premium grade gasoline (91-93octane).
Now to the numbers you want to know about! POWER like you’ve never seen from a 3rd Gen Mazda 3 with the Turbo Kit. Many said the high compression Sky-Activ couldn’t handle boost…many said they are “glass” engines”…we are here to tell you they are wrong.
How about 9.5psi of boost and gains of 115-125whp/80-90wtq? All on the stock fuel system and simple premium pump gas?
In this dynograph you can see four dyno runs. The two lower runs are from our 2018 Mazda 3 2.5L MT. This is a 100% stock car with no tuning changes. The much nicer two runs are the final result of 9.5psi for the CorkSport Turbo Kit.
Power is not just about a peak number, power (and a resulting fast/fun car) is about the power under the curve. Our goal was to develop a kit that made a fast and fun car throughout the rpm range of the 2.5L SkyActiv. With a huge increase in torque across the rpm range, you have a car that will be fun from 3500rpm to 6000rpm before power starts to fall off. This is the 3rd Generation Mazdaspeed that Mazda never gave us.
How does the powertrain handle this? We have only used OEM stock engines, clutches, and manual transmissions in our in-house testing. This goes for our street can and track-only racecar.
However, our in-house testing has been successful with OEM components, our beta tester did have an OEM clutch slippage early on in their testing. Our review of the clutch and the history of the clutch showed us that we are at the limit of the clutch. If the clutch has lots of wear and tear it may not last long with the added torque from the turbo kit. Therefore we cannot guarantee the successful ability to use the OEM clutch equipped in your Mazda.
With that being said there are options on the market for performance clutches that are either available now or are in development. We are personally working with X-Clutch to develop a performance clutch for the community.
Let’s wrap this up…the most complete and ready-to-run turbo kit available for your 2.5L MT Mazda 3. You can make power with easily accessible pump gas up in the 280+whp range and enjoy the daily drive and track. There will not be any surprise runs to the hardware store, as long as you have some wiring supplies, and you could get this done over a long weekend with a buddy that knows how to wrench.
Speaking of the install, the kit can be completed in a long weekend. If you work diligently we’d say 2-3 days to get it done. Follow the color step-by-step online PDF instructions and review the youtube video install before you get started to have the best success.

We also have a specific video for the TurboSmart E-Boost controller setup so you know you get it setup just right. While this project can seem daunting at first, we promise it all comes together if you follow the detailed instructions.
What’s this going to cost you? Less than you expect to be honest. Look at the ND Miata Turbocharger/Supercharger Kits and you would have a good idea of what it should cost, but really we want the community to get this kit and enjoy it so we’ve worked hard to provide the most value for the price on the Turbo Kit.
