The Wait is Over for the 2021+ Mazda Turbo Downpipe

Fits Models Mazda 3, CX-30, CX-50

Unleash the potential and growl from your car and take the step forward into more power! A full 80mm Turbo Back exhaust is now possible with CorkSport’s new Catted Turbo Downpipe for the 2021+ 4th Gen Mazda3 Turbo (as well as CX30 & CX50 Turbo Models)!

Best Mazda Catted Downpipe Kit from CorkSport

Our downpipe uses a two-piece design, making installation easy without the need to wrestle with a single large, cumbersome pipe. The Downpipe starts with a high-flowing cast 304 Stainless Steel Bellmouth, then joins the 80mm mandrel-bent piping with a V-band connection for a leak-free seal.

We used 3D scan data from the OEM downpipe when designing our CS pipe, which means fitment is just like OEM and the CorkSport Downpipe will fit with any aftermarket Cat-back exhaust system, or even OEM!

A high-flow 300 cell Catalytic Convertor is utilized in our downpipe and has been tested to have no significant effect on power potential.  A catless option is not available.

Do I Need A Tune?

Addressing the other elephant in the room: Tuning. We highly recommend getting a tune after installing the 80mm downpipe as there are very strict airflow limits in the stock tune that severely limit power. This will result in some mild stutters, surging, or “hiccups” at wide-open throttle. This does not do any damage as it is simply a very conservative safety limit for stock components.

With more flow-efficient parts (i.e upgraded intakes , Turbo Inlet Pipe, and exhaust systems), these limits are being reached much easier and the ECU will limit the power output of the engine. The vehicle will be drivable on the stock tune and still give you an aggressive growl out of your 2.5T!  

Here you can see the power gains with a fully-bolted Mazda 3 Turbo that is tuned vs stock downpipe and stock tuning.

5 Reasons You Need The Cold Air Box Intake System for the 2019+ Mazda 3 Non-Turbo

The CorkSport Cold Air Box for the 2019+ Mazda 3 has finally arrived!  Long awaited since the introduction of the CorkSport Short Ram Intake for the non-Turbo Mazda 3, CX30 and CX50; the Cold Air Box is ready to team up with your SRI and give you the increased performance from cooler ambient air that you’ve been looking for.  

Installed for the Best Cold Air Intake Box

Designed For Performance

Designed specifically for the non-turbo models in conjunction with the CorkSport Short Ram Intake; this creates a complete performance cold air intake system that bolts in with ease.  

To maximize potential airflow AND keep the hot engine bay air away from the intake we incorporated the OEM intake snorkel and opened the airbox end to take in cooler ambient air from the fender area.  

Mazda 3 2019 and newer cold air intake box

Here you can see the open end of the CorkSport Airbox providing full airflow to the filter from the fender area and the opening on the front of the airbox for the snorkel to interface.  The result is maximum airflow and minimal hot air from the engine and radiator.

Tested & Approved

To validate this design we did on car testing in real-world situations.  Below you will see a graph showing air intake temperature of the CorkSport SRI only vs the CorkSport SRI + Cold Air Box.    Both tests use the same car and begin testing with an up-to-temp car in approximately 80 degF sunny weather.  

Cold Air Intake Data for the Mazda CS Air Box

The testing starts with a 5 minute idle period to simulate sitting in traffic or staging line at a drag race.  This is the “heat soaking” that is so commonly mentioned in social media channels.  After that, the car is moderately accelerated to 50mph which pushes fresh ambient air into the intake snorkel and fender area.  You can see that in both stationary and moving testing, the cold air box keeps intake air temperatures cooler by approximately 10 degF.

Efficient & Responsive

Is a cold air box necessary for your Mazda already equipped with the CorkSport Short Ram Intake?  No, but the cold air box WILL help your engine breathe easier, run more efficiently and feel more powerful and responsive in all driving situations.  It will help make your Mazda even more fun to drive, which is why we all do this!

Built CS Strong

Now let’s talk about the construction of the CorkSport Airbox.  CAD designed and manufactured via a rotor molding process allows us to create very unique shapes that can fit in the engine bay.  The material is XDPE plastic that is very durable and resilient to engine bay temperatures and chemicals.  In fact, it’s the same material we use for our Mazdaspeed Fender Fuel Cell and the 4th GEN Mazda 3 Turbo Inlet Pipe.  The translucent cover is a grey/brown tinted acrylic material that is durable and looks fantastic in the engine bay.

With the removable cover, servicing is super quick and easy, so you don’t have to remove the entire airbox just to clean your air filter.

The Best Camber Plates for the Mazda 3 & CX-30

We are excited to announce the release of the CorkSport Camber Plates for both the 4th GEN Mazda 3 and the 2020+ Mazda CX-30.

You likely already invested in our SRI and rear sway bar, but if you are looking to further enhance the driving characteristics of your Mazda, the CS Camber Plates are a great mod to add to your build. Whether you want to fine-tune your setup for the track or you are looking to upgrade to a more aggressive wheel and tire combo, the CorkSport Camber Plates will give you the extra adjustability needed. Continue on reading for more details on the CS Camber Plates.   

Mazda 3 Hatchback Camber Plates

The camber plates are designed to take the place of your factory strut top so that whether you are on lowering springs or factory springs, installation is quick and simple. For previous generation camber plate kits, it was required to cut the top of the strut tower to gain access to the camber plate to be able to adjust it while installed. This is not the case, however, for the 4th GEN Mazda 3 and CX-30! Making camber adjustments is easy and if they ever need to be removed, permanent modification was not required during installation. The Mazda 3 Camber Plates also feature a pillow-ball bearing that replaces the factory rubber mount and makes sure that the strut bar does not move excessively while driving in demanding situations.  

Mazda 3 Turbo 2.5 Camber Change

Now let’s get to the amount of camber adjustment the CorkSport Camber Plates provide. On the Mazda 3 you can expect camber adjustment ranging from -2.4 to +0.9 degrees. There is a noticeable difference between the two, so if you are looking to fit a more aggressive wheel and tire combo the camber plates may help you achieve it without rubbing the paint off your fenders. The camber adjustment will also help if you plan on tracking your car or want to fine-tune your setup to your driving style on the backroads.     

Mazda 3 2.5T Stock Camber

Finally, let’s go over the construction of the CorkSport Camber Plates. The camber plates feature a top and bottom plate. The top plate houses the adjustment slots for the lower plate and is made out of 6061-T6 aluminum that is then CNC machined. The lower plate features the pillow-ball bearing and is manufactured out of steel to provide the necessary strength needed to secure the strut in place so it does not move during hard driving. Also included with the CS Camber Plates is all the necessary hardware so you can get back out on the road to find your optimal camber setting quickly.   

The CorkSport Camber Plates are a great mod to continue to enhance the handling performance of your Mazda 3 or CX-30 and also if want to build upon the aggressive appearance at the same time. Be sure to check out the website for additional photos and video on the camber plates and feel free to contact us with any questions you might have.

The Performance Rear Motor Mount For 4th Gen Mazda 3 is Ready For Action

If you’re looking for a performance part for your Gen 4 Mazda 3 & CX30 to elevate the driver experience then the CorkSport Rear Motor Mount. This CS RMM is designed to fit any 2019+ Mazda 3 & CX30 whether it is AWD or FWD, Turbo or NA, MT or AT. The key focal point for this RMM is to offer the driver additional feedback for what the car is doing when driving hard. The CS RMM helps eliminate the excessive engine movement, increase throttle response and provide a more solid shifter feel if you have a car with a stick.

Starting with the main body of the CorkSport RMM, it is manufactured from A356-T6 aluminum to provide a robust and light weight mount that effectively replaces the quite large and heavy OEM mount. The factory mount features a large rubber center section which contributes to the excessive engine movement and additional weight. For the CS RMM we decided to add smaller bushings towards the front and back of the mount which allowed us to save material and weight.  Below you can see the two RMM’s compared against one another.    

Mazda 3 Performance Race Poly Mount

Now onto the polyurethane bushings, which play a big role in the increased driver feedback and reduction in engine movement. We tested the selected 70A bushings extensively and found that they offer a good combination of providing both a noticeable improvement in the driving experience while not introducing to much extra noise, vibration, and harshness (NVH) into the mix for daily driving.

NOTE: NVH (noise, vibration, harshness) is a standard term used in the automotive industry.  NVH is a byproduct of changing some OEM components to aftermarket components in the pursuit of focused performance. Example of components that can increase NVH: engine mounts, clutch/flywheel, intake, exhaust, suspension, tires/wheels…and many more. 

During the first stage of testing we started out with only two poly bushings in the front of the RMM, but after further testing we found that adding an additional two bushing to the rear of the RMM provided much lower NVH while still reducing engine movement considerably.

The last piece that is fundamental in the CS RMM is the bushing sleeves. The sleeves provide the ability to install hardware through the polyurethane bushing without having the bushing itself compress and possibly crack when applying torque to the bolt and instead transfer the force into the sleeve. The bushing sleeves are precision machined out of steel for strength and then zinc coated so they will not corrode over time and wear out the polyurethane bushing prematurely.

Ok, so now how does the CS RMM improve the driver experience? Well, the factory RMM allows the motor to rotate a good amount which helps provide a smooth driving experience for around town, but this increase in engine movement decreases the throttle response and shifter feel.

This is because the motor is allowed to rotate a certain amount before the wheels do, so by decreasing the amount the motor has to rotate, allows the wheels to start rotating sooner, thus increasing the responsiveness of the car. This reduction of movement also provides a better shifter feel if you have a manual because there is less movement between the connection of the shifter and transmission.

What to expect from the Rear Motor Mount:

From our testing in multiple R&D cars and beta tester cars and the thousands of miles driven…it’s awesome!  From about 2000rpm up to redline you are going to feel a smooth engine that loves to give you feedback on your throttle, shifting and engine braking.  Below 2000rpm to idle you may notice some vibration, especially when the A/C pump is in operation. 

Thanks for checking out the CorkSport Rear Motor Mount for the 4th Gen Mazda 3 & CX30! If you want to add this mod to your Mazda and get all the benefits discussed above, be sure to head over to the product page for more details.
