We are proud to introduce the CorkSport HPFP Rebuild kit for the Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7 Turbo. Replace every seal in your HPFP with a brand new, E85 safe O-ring/X-ring made to exact OEM specifications. The perfect reliability upgrade to install with your CS HPFP internals, we even include new hardware and a security Torx bit to help the install go smooth. Read on for more details and be sure to give us a call if you have any questions!
While the HPFP internal upgrade is a must-have mod for any Speed, the rest of the HPFP is commonly ignored. As the cars get older and ethanol blends are used more often, the factory O-rings can begin to break down, causing fuel dilution in your oil, and the potential for HPFP failure. The CS HPFP rebuild kit replaces all your seals so you can be confident that your HPFP is performing exactly as intended.
With the MS3 and MS6 coming out right around the time ethanol mixes in gasoline were becoming more common, it’s hard to say if the HPFP system was ever designed with ethanol in mind. We spent months researching and testing on a car and in isolated conditions to find the best O-ring material for gasoline and ethanol blends. Each seal in the CS HPFP rebuild kit uses this material so your Speed will operate properly no matter if you’re using the standard pump gas E10 mix, and E30 mix, or even straight E85!
To ensure the correct size for all seals, we were lucky enough to come across a zero mile DISI MZR engine. The HPFP was disassembled and all seals were carefully measured to ensure each O-ring exactly matches the OEM specification. We even had tooling made to produce a custom X-ring that matches the exact specification of the OEM X-ring. This is vital as the X-ring fits on your HPFP piston and needs a precise fit to ensure an OEM quality seal between the fuel chamber and your cam follower.
Lastly, we include hardware to replace the annoying Torx screws that are used in the OEM HPFP assembly. The small security Torx can be notoriously difficult to remove, so we even include a bit to help with removal. As with all CS products, the HPFP rebuild kit comes with full-color installation instructions to guide you through the rebuild and ensure you know where each and every component goes.
If you’re looking for big power (500+whp) potential for your Mazdaspeed 3 and don’t want to be held back by your intake system then look no further!
Introducing the CorkSport 4” Intake system for ’07-’13 MS3 (Gen1 and Gen2). Featuring mandrel bent piping, a billet MAF housing, and a large aFe dry flow filter; you can get the benefits of a huge 4” intake with the easy fitment of a smaller intake. We went back to the drawing board for this intake to optimize both fitment and performance. Read on for details!
We truly started from scratch to ensure the best fitment for this intake. The main change is the way the silicone couplers attach to the turbo inlet pipe. To get the pipe as close to the engine as possible for easy fitment, we use a custom-designed coupler off the compressor of the turbo. The 4” intake pipe fits straight into this, making install just that little bit easier. The biggest change though came at the MAF housing connection.
Instead of using a silicone coupler between the turbo inlet pipe and the MAF housing, the billet MAF housing is TIG welded directly onto the turbo intake pipe. This further helps fitment and helped us maximize filter size (more on that later). What this means is that you end up with a four-inch intake that takes up less room than some 3.5” intakes on the market while retaining the OEM mounting points and OEM BPV, PCV, and boost vent ports. It even fits with our 51R battery box!
The benefit of a 4” intake system is in the flow capacity. Moving up in intake size, even from a 3.5” to 4” offers an increase in maximum flow capacity. A bigger intake equals the potential for a larger volume of air ingested by the engine, which equals bigger power potential. You also increase the maximum airflow that can be read by the MAF sensor before it peaks, but you must get a tune to scale the MAF sensor.
So what does this mean for power gains? Typically, a lower horsepower car will not see a power bump but, big power MS3’s can see an increase in power, just by reducing the airflow restriction before the turbo. While you may not quite be at a 3.5” intake’s limit at 600WHP, moving to a 4” intake will increase the efficiency of your build and reduce the strain on your turbo, with a chance at some extra ponies along the way!
Increasing piping diameter only does so much if you have a highly restrictive filter. We focused heavily on fitting the biggest filter we could to minimize restriction coming from the filter. We chose aFe’s Pro Dry S material for great filtration and flow, without having to worry about an oiled filter dirtying the MAF sensor. Check out the image below comparing the new 4” intake filter to the filter used on our 3.5” intakes. The new filter’s media is larger than the entire old filter!
While the new CorkSport 4” Intake may be a bit different from our normal intakes, we kept the same billet MAF housing design. A billet machined MAF housing ensures accurate and consistent diameter around the MAF sensor itself vs just using a pipe or plastic MAF housing while also letting us have a TRUE 4-inch inner diameter. This ensures that once calibrated, your MAF sensor will read stable and accurate. To be extra sure MAF readings are great, we pre-install air straighteners to ensure your MAF is getting clean and straight air.
With the consistent CNC machine inner diameter at a true 4 inches and the integrated air straighteners, you can daily drive your Speed with this 4-inch intake system and have MAF sensor range over 900whp.
Each CorkSport 4” Intake System is made from mandrel bent 4” 6061 aluminum tubing for smooth airflow directly into your turbo. The billet aluminum MAF housing is TIG welded into position, as are all ports and brackets to ensure long-lasting strength. Each intake is finished off in a wrinkle black powder coat for a clean look that will match just about any engine bay. We also include your choice of 4-ply reinforced silicone coupler for the turbo inlet. We have 4”, 3”, and OEM diameter silicones so you can be sure your turbo with work great with the CS 4” intake. To finish it off, we include stainless steel T-bolt clamps for the connections, to prevent any vacuum leaks.
The CorkSport 4 Inch Intake System is a complete package that can help you make big power on your Speed 3. Increase flow capacity and filter size to help that turbo breath better so you can make more power for longer. Check out the product listing for more images and don’t hesitate to give us a call if you have any questions!
Love your new Mazda 3 but find yourself missing some excitement? Already have our Short Ram Intake and out Strut Tower Bar? CS has come to help. We are proud to announce the CorkSport Axle Back Exhaust for 2019+ Mazda 3 & CX-30! Add some much-needed volume to your 4th GEN and help the engine breathe while doing so. It’s a great balance of growl under hard acceleration, yet quiet while cruising, plus you get a nice visual boost to the back of your ride. Read on for full details, and be sure to check out the product video for sound clips! (Mazda3 pictured below is OE ride height. If you are looking for more low, check out our 4th Gen Mazda 3 Lowering Springs!)
The CorkSport ABE replaces the restrictive OEM muffler section with high flowing, mandrel bent 304 stainless steel piping and a pass-through resonator. This allows for a great sound that is just loud enough to make your backroads journey fun without ruining your daily commute. The tone is deep with some nice growl to it that you’ll love to hear. Due to the unique, offset inlet flange, we ended up going with the single asymmetrical resonator for the best tone combined with drone elimination. We tested multiple resonator combinations before determining the single long resonator was the best setup.
The sound was not our only focus, however. We’ve increased the piping diameter to minimize flow restrictions in the exhaust. The piping diameter was increased from the OEM of 50-55mm (depending on where you measure) to 63.5mm (2.50 inch). The OEM muffler section has a lot of twists, turns, and flow restriction to quiet down your Sky-G. The free flowing resonator eliminates this flow restriction, and when combined with the larger piping, lets the 2.5 breathe better.
The sound and performance also comes with a visual gain. Exhaust tips are increased in size up to 90mm to better fill in the bumper cutouts of the BP Mazda 3. Each tip is dual wall construction that uses a rotated slant cut design. This helps the tips follow the curve of the bumper just like the OEM tips. Each tip is finished off with a laser engraved CorkSport name badge for a nice detail.
The GEN4 Mazda 3 exhaust also allowed us to bring in a feature we have never had before: adjustable tip length. Each tip is attached using a slip fitting and exhaust band clamp to provide secure and exhaust-leak-free performance. This slip fitting gives you up to 10mm of length adjustment to really dial in the look you’re going for. That is not even the best part though! We are offering three different tip length options for you all to choose from: Hatchback, Hatchback w/Appearance Kit, Sedan, and CX-30.
The sedan tip option is the longest in order to fit the longer rear end of the sedan models. While not intended you could put these on a hatchback if you’re into the “blast pipe” look.
The Hatchback W/Appearance Kit tip option is the medium length tip. These are intended for hatchbacks equipped with Mazda’s factory Appearance Package and are also the optimal length for the CX-30. This offers an aggressive look to match the aggressive nature of the Mazda Aero Kit. These tips can also be used on a non-aero kit hatch, however, they would stick out too far for most people’s taste.
The Hatchback without the Aero Kit tip option is the shortest option and is intended for regular hatchbacks without the Mazda Aero Kit. You can also run these tips on hatches with the aero kit if you’re going for a more conservative look, but they tend to disappear in the bumper skirt.
As usual, each CorkSport 2019+ MZ3 axle-back exhaust is made entirely from polished 304 stainless steel for the best in appearance and corrosion resistance. Each joint is TIG welded for strength while the inlet flange is laser cut to ensure a perfect fit. Each exhaust comes with all hardware needed for install, including exhaust clamps for the tips. You also get full color installation instructions and support for any installation questions you may have.
We strongly encourage you to visit the product listing for more pictures and to check out the product video for sound and video clips. This exhaust is fantastic, especially for a daily driver. Let us know what you think, and share other 4th GEN parts you want to see!

The 2019+ Mazda 3 handles surprisingly well, even with the new torsion beam rear suspension. If you’re looking for even better handling out of your GEN4 3, we are happy to help! Introducing the CorkSport Front Strut Tower Brace for 2019+ Mazda 3 Sedan & Hatch. Improve driver feedback, add stability, and improve your confidence through the twisties in as little as 15 minutes! As a bonus, it even offers a visual boost to your engine bay. Read on for full details and don’t hesitate to call us with any questions!
The CorkSport Strut Bar connects the front strut towers together to improve chassis stiffness. By connecting the left and right strut towers together, flex in the strut towers themselves is reduced during hard cornering. This helps the suspension better do its job. This is most easily noticed through better driver feedback, so it’s easier for a driver to know what the car is doing when in a corner. There is also added stability, especially at a higher speed. Both of these aspects combine to help with driver confidence so you can attack your favorite backroad.
In order to offer the biggest handling improvement, we chose the best balance of strength and weight. The center bar section is made out of 2024-T4 aluminum so we get plenty of strength but keep the weight down. The two end brackets are made from laser-cut carbon steel that is precision welded together for the utmost in strength to give a solid base for the lightweight center section.
You can’t have all functions with no form though! To give a classy visual boost to your engine bay, the center aluminum section is fully polished and finished off with a CorkSport name badge for a clean look. The end brackets are powder coated black for long-lasting corrosion resistance and a clean look that will match just about any engine bay.
To provide the best experience for you all we include full-color installation instructions and all the hardware needed for installation. The center section of the brace is attached to the end brackets with chrome-plated hardware for long lasting good looks and strength. Also included are new strut mounting nuts to ensure good thread engagement and a final shiny touch. This means a typically install only takes 15-30 minutes with minimal tools required!
If you’re looking for an easy first mod on your new 3 or are wanting something to compliment your new CorkSport lowering springs and Short Ram Intake, the CS Front Strut Bar is a great option. We’re excited to see what you all think of the new strut brace. Check out the product listing for more pictures and to purchase!
2019+ Mazda 3 – Front Strut Tower Bar is ready for action! August 13th, 2020Sky
We hit a great balance between a street and track setup so you can have plenty of fun whether your corner of choice is on a backroad or an autocross course and still be comfortable on the daily commute.
Along the same line as our MS3 kit, we diverged from the normal spring rates chosen for 3rd GEN coilover setups. We really wanted to strike a good middle point between a basic street coilover and a full race setup.
With that in mind, spring rate selection was critical to ensure a stiff enough setup for good track handling but soft enough for regular roads.
The final rates we ended up at were 7K linear front springs and 8K linear rear springs. We prefer linear springs so that the car will react the same no matter the corner or bumpiness of the road. This provides a ride that is stiffer than stock but is not harsh or uncomfortable. This is coupled with more neutral handling (less understeer) and a suspension natural frequency that is slightly higher in the rear than the front for added driver feedback and comfort.
To further add to the handling benefits, the CS coilovers have 15-way adjustable rebound damping in both the front and the rear. This allows you to tune your ride to exactly how you like it, whether you’re going for comfort or handling. It’s even easy to use one set up at the track and then soften things up for the ride home! The front also comes with adjustable camber plates for fine-tuning camber for handling or fitment.
Obviously, there’s one big component that we haven’t talked about yet: ride height! The CorkSport Coilovers offer approximately 2 inches of ride height adjustment, with the highest option being roughly 0.5” lower than the OEM suspension. This is enough adjustment to go from an “OEM+” setup to a low setup that will turn heads and everything in between. This isn’t just about looks though as a lowered ride height offers a lower center of gravity, reduced body roll, and improves driver confidence.
One final unconventional touch is the inverted monotube design of the front coilovers. Instead of a more conventional and cost-effective design, this uses a 180° rotated damper design. This improves the rigidity and reliability of the strut while also removing a little bit of unsprung weight. You get great driver feedback from this style of design, which is why we specifically chose it!
The CorkSport Coilover kit is a great upgrade for whatever corner you want to throw at your GEN3. Be sure to check out the product listing for more details and images.
Don’t hesitate to call us with any questions you may have as well, we’re happy to help!
