It’s time to liven up your 4th GEN Mazda 3 Sedan with the new CorkSport Performance Lip Spoiler for 2019+ Mazda 3 Sedan and 2021+ Mazda3 Turbo Sedan. While Mazda did a good job creating classy styling for the newest 3, we find it to be a little boring, especially when on lowering springs and a nice set of wheels. The CS spoiler offers a much more aggressive trunk lip than the small OEM Mazda unit, without detracting from the great OEM styling. Its features incorporate the original Mazda body lines to stand out without being obnoxious. Keep on reading for full info and pictures!
A Stylish Spoiler For The Mazda 3
Like its hatchback counterpart, the CorkSport sedan spoiler offers an “OEM+” look. We took the body lines and design cues of the Mazda 3 and adapted them into a more aggressive spoiler than is offered by Mazda. It extends and raises the rear edge of the trunk to finish off the vehicle’s rear better. The CS spoiler also carries over the tops of the rear quarter panels and ties into the main body line. The rear face of the spoiler follows the taillights before moving upward at the same angle as the end of the lights for extra detail. Finally, the spoiler’s top and rear faces are concave for a bit of a “duckbill” type of look. These features combine to ensure the CS spoiler looks at home on a 4th GEN sedan and will make you wonder why Mazda did not have something similar from the factory.
The Best Spoiler Fitment for The Mazda 3
Fitment was as important as styling, so the design began with a 3D scan of the trunk and rear quarter panel area. This scan was used as the base for the entire design that was completed in CAD software. After many test fits and iterations for best fitment, we were left with a final design that matches the OEM curves very well and can be installed with no drilling or trimming.
Carbon Fiber & Fiberglass Options
After the fantastic response we received on our material choices for the 4th GEN Mazda hatchback spoiler, we knew we had to do the same thing for the 4th GEN 3 sedan. Each CS trunk lip is made from a fiberglass foundation before being topped with your choice of 3 materials. Full fiberglass, woven carbon fiber, and forged carbon fiber are all available. The two carbon options are finished off in a UV-resistant glossy clear coat with a mirror-like finish. The regular fiberglass will come in a satin black finish that is ready for light sanding and a finish coat of paint or wrap. Each material has the same shape, but you can personalize the look to match your build and budget.
Easy to Install
Installation of the CorkSport Mazda3 trunk spoiler could not be any easier. It is attached with included 3M VHB tape for a simple and secure fit with NO DRILLING. If you have the OEM Mazda lip spoiler, installation is a little more difficult as you have to remove it to install the CS, but we include covers for the holes that are no longer used with the CorkSport spoiler. Full-color installation instructions are also available so you can transform the rear of your sedan in as little as 30 minutes!

Let’s face it, the first-gen Mazdaspeed3 platform is aging, and with that age comes ugly, yellow plastic tanks. We’ve even seen tanks crack and fail, causing coolant leaks, headaches, and eye sores for owners. It’s time we changed that.
CorkSport has developed a solution in the form of an aluminum replacement for these tired plastic tanks that fit and function just like OEM! Our tanks also come coated in a beautiful black powder coat that will look right at home with any color in any engine bay. Our tanks are robust and will stand the test of time for years to come.
But why aluminum? Why do we even have a tank, to begin with? What does it do?Let’s start by going over how a cooling system works.
TW: It’s about to get a little nerdy!
Understanding Heat Transfer in Cooling Systems
Think about a hot summer’s day. You’re sweating from a hard day of wrenching on the Mazda in the garage and desperately need a cool down, so you place a cold, wet, refreshing towel around your neck. Initially, when you place that cool towel around your neck, you only feel the cold in one place: around your neck. But pretty soon, you feel the cold spread throughout your body and begin cooling down.
This feeling, however, is misleading as there is no such thing as “cold.” There is only heat and a lack of heat. What’s happening is the heat that you feel on your body is being transferred into the cool towel, and the blood that passes through your neck is cooled as a result. As this blood with less heat (i.e., “cooled”) circulates around your body, you feel the effect of that towel all throughout until all of your blood is cooled, and you begin to feel better! You’ll notice after some time that the towel is no longer cool because it has absorbed the heat from your body and the surrounding air. Remember: heat moves from hot to cold and wants to spread until an equilibrium is met.
How Automotive Cooling Systems Work
Automotive cooling systems work on the same principle. Replace that towel with a radiator, your blood with automotive coolant, and the engine as a heat source, and now you have an automotive cooling system! As the cold coolant passes through the engine, it absorbs the heat generated by the combustion cycle and friction in the cylinders. Some of this hot coolant is then passed through your HVAC system, where some of this heat can be used to heat the cabin (this is how your heater works), and the rest is passed to the radiator for cooling. Once cooled by moving air, it is then passed again into the engine, where it works to cool it down. Then the cycle continues. This is the same basis of how Turbo front mount intercoolers operate. For more information on these systems, check out our Front Mount Intercoolers.
So where does the tank come in?
Naturally, as things heat up, they expand. Coolant is no exception to this rule, and this is usually combated with an expansion tank to capture any excess volume. What makes the MazdaSpeed 3 cooling system unique is that the expansion tank is incorporated into the main flow path of the coolant, with the expansion volume built into the reservoir design. This design of combining the expansion tank with a reservoir simplifies the system without the need for additional tanks or hoses. This can also be compared visually with the fill point of the cooling system. On most vehicles, it is located on top of the radiator, but on the Speed3, it is located on the tank directly. This means that the tank itself is pressurized when the system is hot, which introduces a challenge with material selection.
Mazdaspeed’s Need For A Better Tank
Since the OEM tank is made of plastic, it is more vulnerable to degradation over time. Once the tank has deteriorated enough, it cannot withstand the pressure changes and high-temperature cycles of the coolant system. It will eventually fail, leading to many owners complaining of cracks and leaks. The TIG welded aluminum construction and powder coating of our tanks mean that they are substantially more resilient than the OEM tanks and will last for years to come.
Power Steering Tank
The 2007-2009 Mazdaspeed 3 power steering tank is much simpler as its only function is to hold fluid, and the system is only slightly pressurized, meaning no expansion volume has to be built into the tank design and the temperatures are much lower. However, the OEM tank is still made of the same ugly plastic as the coolant tank and has the same disadvantages. While this tank does not see the same failure rate as the coolant tank, we decided to take the opportunity anyway to fully complete the look of the engine bay and provide our customers with a comprehensive solution to replace all of the aging plastic tanks to improve the appearance of the engine bay vastly.
Fitment and Design
We understand that universal tanks are such a pain. We have experienced this with some of our cars and have had to design and fabricate custom brackets to make them fit. This is a headache, not to mention having to cut or move OEM hoses or custom-make our own. Retaining OEM fit and function is the easiest and most effective design for installation, and that is exactly what we have done for our tanks!

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.
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.
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.
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.
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.
