New Rear Motor Mount Insert for 2019+ Mazda 3 and CX-30 Owners

For those looking for a Rear Motor Mount upgrade for your 4th GEN Mazda 3 or CX-30 but don’t want to add too much additional NVH, we are excited to release the CS RMM Inserts. The CS Inserts utilize the OEM mount and offer performance quality between the stock and CS Rear Motor Mount. This means you will get less NVH from the upgrade when compared to the CS RMM, which will be great when driving around town. While not being as aggressive as the full replacement CS RMM, you will see a nice improvement in feedback and responsiveness when pushing it on the back roads or in other situations in which you are utilizing the full potential of your Mazda. If you are interested in this new option, keep on reading for more specifics on how the CS RMM Inserts were designed. 

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. Examples of components that can increase NVH: are engine mounts, clutch/flywheel, intake, exhaust, suspension, tires/wheels…and many more. 

Rear Motor Mount Insert for 2019+ Rear Motor Mount OEM

During the design process, we started with the Mazda 3 OEM rear motor mount and worked on modeling inserts that would completely fill the two openings. Once the initial designs of the two inserts were completed we began testing the samples and started with both front and rear inserts installed at the same time. Our initial impressions were quite surprising. We found that this combo resulted in the same if not more NVH than when the full CS Rear Motor Mount was installed.

Since the dual combo didn’t get us to where we wanted, we then tried each insert one at a time. This helped quite a bit and reduced NVH down closer to where we wanted. The issue we encountered when using only one insert was that the gear with worse NVH varied depending on whether we were in drive or reverse. This led us to trim and remove sections of the front and rear inserts to try and get the best of both worlds. By removing the center of the inserts, we were able to find a design that operated in line with our target performance levels. It ended up being a good middle ground between the stock and CS RMM. A comparison of the performance can be seen in the video below showing all three options.       

Now onto some other specs of the CS Inserts. The durometer of the polyurethane we selected for the front and rear inserts is 70A. This gives the inserts enough flex to be installed into the mount without too much effort. This all allows for a tight fit so they do not work their way out during operation. Locking tabs were integrated into the inserts to ensure they remained installed in their correct position.

The Wait is Over for the 2021+ Mazda Turbo Downpipe V2

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)!

2021 Mazda Turbo Downpipe

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!

Best Downpipe for the 2021 Mazda 3 Turbo

An updated high-flow catalytic converter is utilized in our V2 downpipe. Our V1 downpipe used a Euro 3 300cel catalyst that showed mixed results with check engine lights (CELs). Our new and improved V2 unit uses a Euro 6, 500cel catalyst for the best in emissions control while minimizing those pesky CELs. Euro 6 is (generally speaking) a more strict set of emission parameters than in the USA. We also went for a more dense catalyst (500cel), which, when combined with an upsized 5” diameter, showed no significant power difference from the V1 300cel or even a fully catless prototype unit (catless not available).

The updated catalyst has shown no check engine lights through our testing. We cannot guarantee no CELs as testing all possible climates, driving conditions, local fuels, elevations, and any and all combinations of these is nigh on impossible! However, we are happy to report no CELs through ~10 months and ~14,000 miles of driving!

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.

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.

2021-up Mazda 3 Turbo and CX30 Turbo Intake Heat Shield

Cold air vibes for your Mazda 3 turbo

Have you been waiting for the CorkSport Heat Shield to go along with a CS SRI to snag one? Well you don’t have to wait any longer because the CS heat shield is here! Whether you have the CS SRI already or want to get both at the same time, the CorkSport Heat Shield for both the Mazda 3 and CX-30 with the SkyActiv 2.5T is a great mod to include in your build. Keep on reading to see how the CS Heat Shield is able to achieve lower intake air temps that allow your motor to make power easier.

Mazda 3 turbo engine bay intake heat shield

For the Mazda 3 Turbo Heat Shield our main focus was keeping cool air supplied to the filter. The shield was designed to seal off the intake from as much heat produced from the radiator, engine and transmission as possible. This lead to a multiple piece design that is riveted together which allows us to utilize the OEM air ducting which supplies cooler outside air to the filter. The shield does not fully surround the filter because we have also found that there is cool air that also comes from the area in front of the tire and underneath the headlight while driving, helping to ensure that your intake sees as much cool fresh air as possible.

Mazda Cx30 Performance Intake Heat Shield

Now with all of this cooler air being supplied, how does it help performance? The basic concept is that since cold air is denser than warm air, your engine gets more air per cycle, and thus allows more fuel to be added to make more power. However, when a car is turbocharged, the process is a little more complicated. A turbo compresses and heats up your intake air and then sends it to an intercooler that cools the air back down. What that means is that the “colder air will make more power” generalization may not be as significant, especially with the advancements in modern turbocharged vehicles. Colder intake air does offer a benefit in the form of less stress on your turbo system. This means that your turbo does not have to work as hard to flow the same amount of air at the same boost pressure. Also a reduction in intake air temps can translate to slightly cooler air exiting your turbo compressor, which helps take some stress off the intercooler as well.

Mazda 3 turbo cold air intake heat shield installed

With all of the theory covered, let’s get to the real world results! In daily driving testing we found decreased intake air temps with the CorkSport Heatshield installed. When cruising or when it’s cold outside, we were actually surprised at the low intake temps of the CS SRI alone—there’s actually a surprising amount of fresh air that gets into the engine bay. Where the heatshield really comes into its own is when sitting stationary or driving on a very hot day. That’s when we saw our biggest improvements in intake air temp.

3 cold air intake heat shield test data

Lastly about the manufacturing, the CorkSport Heat Shield is made out of carbon steel that is laser cut and precision formed. Carbon steel was selected for its strength and lower heat transfer over aluminum. To fight off corrosion, the heatshield is powder coated wrinkle black and gives the heat shield a great look that helps it blend in with the other parts in the engine bay. Both sections of the shield are attached together using stainless steel rivets for corrosion resistance and a nice look. Lastly, we include rubber seals along the top edge of the CS Heat Shield to keep as much heat out as possible, and to prevent any unwanted vibrations or noise.
