CorkSport High-Pressure Fuel Pump Rebuild Kit

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!

Mazdaspeed E85 Safe HPFP O-Ring Rebuild Kit

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!

CorkSport

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.

Carbon Fiber Engine Cover Release

We are happy to introduce the CorkSport Carbon Fiber Engine Cover for 2014-2018 Mazda 3, 2014-2018 Mazda 6  non-turbo up to 03/02/2018 build date, 2013-2017 Mazda CX-5, and 2016-2020 Mazda CX-3!

Add some much-needed flair to the engine bay of your Mazda in 10 minutes or less. Offered in two different REAL carbon fiber weave patterns with 4 choices of CS emblem colors so you can personalize your look to match your build. Read on for full details and check out the images!

The CS carbon engine cover spices up your Mazda’s engine bay with a fantastic 100% real carbon fiber. You have your choice of weave between a regular 2×2 twill weave or “forged” carbon for a little extra cost. The forged carbon was originally developed by Lamborghini and uses chopped strands of carbon instead of the traditional carbon cloth for a unique appearance. Both are finished in high gloss for a truly great look!

Each CorkSport engine cover is designed to be a direct replacement for your OEM engine cover. We used an OEM cover when creating the design so you can be sure it will fit and look just like OEM. All OEM mounting locations were replicated and then securely bonded to the carbon. The covers sit right where they’re supposed to and don’t cause any vibrations or rattles!

We finished off the CorkSport CF engine cover with a custom billet aluminum “CS” logo badge. It offers a nice finishing touch that replicates the Mazda badge on the OEM cover. To give it your personal touch, four different anodize colors are available: blue, red, black, and silver. Each color looks great with the carbon background, whether you want a stealthy black look or bright red to match your car’s paint and your CS intake!

If you’re looking to add some flair to your engine bay and impress at your local car meet, check out the CorkSport Carbon Fiber Engine Cover. Be sure to check out the product listing for more pictures and don’t hesitate to give us a call with any questions, we’re happy to help!

CorkSport Aluminum Skid Plate for 2017+ Mazda CX-5

We are back with another product release for you CX-5 owners! Say hello to the CorkSport Aluminum Skid Plate for 2017+ Mazda CX-5. Using our tried and true 11 gauge aluminum construction and 2-piece design, the CS skid plate adds some much needed protection to the underside of your CX5. Whether you use your CX-5 for camping, extra snow protection, or as a slammed show car, the CorkSport skid tray is a perfect fit for your build along with our axle-back exhaust! Read on for full details!

The OEM splash shield does a good job at its intended purpose: to smooth the air under your car for efficiency and keep your engine bay components dry. Any impact from road debris, rocks, or even a pesky speed bump though can easily crack or tear off your plastic splash shield leaving you without any protection. The CorkSport Skid Plate replaces the easily broken OEM unit with a full aluminum skid tray that can take a beating. We’ve used and abused these skid trays at the track (and some off-track excursions…) on our Mazda 3’s over the years and they have proven themselves to be sturdy, even withstanding the stresses of the 25 hours of Thunderhill! The CS skid tray will offer better protection for your engine so you can be less worried about your CX-5 when you take it camping on rocky forest roads, up to the mountain through snow & ice, or slam it and take it to shows.

View all Skid Trays

To offer the best experience possible for you all, we have carefully CAD designed the CX-5 skid plate to mount directly in place of the OEM splash shield. This means no drilling, cutting, trimming, or headaches during the hour or less install. We kept the OEM style 2-piece design for further easy installation plus, the bonus of adjustability for minor variation vehicle to vehicle and cheaper shipping! Finally, there is an oil access cover just like OEM that you can move out of the way to easily change your oil and filter.

CorkSport

Each CorkSport CX-5 skid tray is made from laser-cut and precision formed 5052 aluminum. This ensures a consistent product for each of you that will stand the test of time and the elements. Included with each kit is all the extra hardware needed for installation. This includes stainless steel button head bolts that fasten the skid tray to the vehicle. These provide great corrosion resistance and won’t snag as easily as a traditional hex head bolt. We also include Torx screws for the oil access cover. This style of screw prevents the head from stripping after repeated oil changes which are typical with a traditional Phillips head screw.

If you’re looking to add some protection to the underbody of your 2017+ CX-5, look no further than the CorkSport Aluminum Skid Tray! Be sure to check out the product listing for more images and don’t hesitate to call us with any questions.

Axle Back Exhaust for 2019+ Mazda 3 & CX-30!

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!)

4th Gen 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.

CorkSport Axle Back Exhaust for 2019+ Mazda 3 & CX-30

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.

CorkSport

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.

CorkSport Axle Back Exhaust for 2019+ Mazda 3 & CX-30

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!

CorkSport Performance Coilovers for 2014-2018 Mazda 3 and 2014-2017 & 2018+ Mazda 6

After learning a lot from our re-release of the CorkSport Mazdaspeed 3 Coilovers, we decided to use our new design style and apply it to the GEN3 Mazdas. We are proud to introduce the CorkSport Performance Coilovers for 2014-2018 Mazda 3 and 2014-2017 & 2018+ Mazda 6

Before and After

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.

2014-2018 Mazda 3 and 2013-2017 & 2018+ Mazda 6 Coilover Suspension

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.

Shop All 2014-2018 Mazda 3 Parts

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.

Racing Inspired

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.

Long Lasting Quality

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.

Optimized Spring Rates

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!

Adjustability for Street and Track

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.
