Weighing in at a respectable 320 grams, the CorkSport leather shift knob will help smooth your gear changes and customize the interior of your Mazda while doing so. With an ergonomic design and large top surface, the CorkSport leather shift knob is comfortable to use for any grip position. Check out the difference between the OEM shift knob and the CorkSport leather shift knob.
Manufactured from Delrin plastic, then hand-wrapped and stitched with high grade black leather, the CorkSport leather shift knob will stand up to daily driving and track use day-in and day-out. The baseball style stitches are tight and clean, leaving no loose edges to fray or annoy you; and the leather has a slight texture and plushness to it, so it feels great in your hand.
Don’t wait! Get your leather shift knob today before they’re gone!

Fighting boost spikes with the Mazdaspeed K04 Turbo or maybe boost creep with an internally gated GT3076R? Or have you gone all out with an externally gated setup? Whatever the reason, you have probably realized that the OEM boost control solenoid is not up to par and desperately needs something that is reliable and tunable.
The CorkSport EBCS utilizes the latest technology in solenoid-controlled air valves, as well as using a light weight, low friction, and balanced valve design. The CorkSport EBCS will handle pressures from vacuum to 120psi with an operating frequency of 0 – 1000Hz and response time of 700µs.
So what does this actually mean to you?
You can build boost faster, reduce or eliminate boost spikes, and hold boost more accurately throughout the RPM range. Don’t believe me? Then check out the graph below comparing the OEM EBCS to the CorkSport EBCS both in bleed setup.
You can see a noticeable difference between the two graphs. Boost rises sooner, and there is no overshoot with the CorkSport EBCS. With the same Stage 2 tune, only changing the EBCS and adjusting the waste gate duty cycles, we saw an increase of 18 ft-lb of torque at peak due to the more boost at a lower RPM.
Not only does the CorkSport EBCS work great, but it also fits great! Designed with ease of installation in mind, the EBCS can be located in the OEM location, or on the valve cover for turbochargers without the OEM tab. This goes for both TMIC and FMIC setups. There is also no wire cutting or soldering needed! Simply plug the electrical connector into the wiring harness and you are ready to go!
Whether you are just stepping into the Mazdaspeed world or are the horsepower king at the local dyno, there is a place under your hood for the CorkSport EBCS. This will benefit you from K04 turbocharger to an externally gated GT3582R, and there are two ways to look at the CorkSport EBCS. First, it’s a potential power adder due to its far superior response time, efficiency, and accuracy; or second, it’s a safety device for the exact same reasons. Now there is one catch…correct use of the CorkSport EBCS will require adjustments of the waste gate duty cycles. We recommend you contact a professional tuner to setup your new CorkSport EBCS.
Take control of your boost with the CorkSport Mazdaspeed Electronic Boost Control Solenoid! For more technical information check out our white paper write-up of the EBCS.

The Mazdaspeed platform is a pretty well-supported car in the engine performance and suspension market, but it seems to be lacking in some of the markets that truly allow you, as the driver, to connect to the car. This is especially true for the GenWon owners. Well, CorkSport has decided to help the forgotten GenWon owners become more intimately connected to their Speed3. So what are the components of a car that the driver is most intimate with? I would have to say the pedals, seat, steering wheel, and, of course, the shifter.
So which of those did we release? It’s not pedals. (Autozone has that covered.) Unfortunately, it’s not a seat, but that would be awesome. It’s not a steering wheel…yet. (Oops. Did I say that out loud?) I’m happy to say it’s a short shifter, and not the kind that goes under the hood. Sure, there are a few options out there, but they leave a lot on the table and the price seems ridiculous.
Manufactured from high-grade 6061-T6 aluminum, this precision machined double adjustable short shifter is sure to give you that intimate connection and control with your Speed3. Plus, it’s 100% designed and manufactured right here in the Pacific NW, USA.
So what sets the CorkSport Short Shifter apart from the competition? This short shifter is double-adjustable, but not in the way the competition defines it. First, there are four throw positions ranging from OEM throw distance to the 35% shorter throw distance. Second, the shift knob height is adjustable from 11.75 to 9.5 inches tall with the OEM height being 11.125 inches. Lastly, just look at it: It’s gorgeous. It’s a shame it gets hidden under the shift boot.
Take a look at the comparison images below:
This image shows the forward, neutral, and back positions of the OEM shifter.This image shows the forward, neutral, and back positions of the CorkSport Short Shifter in its shortest height and shortest throws position.
Of course, a product like this doesn’t come to life overnight. There were many hours of design, testing, and revision done to verify that the product you receive is the best it can be. Below are a couple images of 3D-printed prototype we made on our 3D printer to help speed up the R&D.
In addition to the prototype testing, we also perform FEA (Finite Element Analysis) on all applicable components to verify they’re strong enough to last for many, many years. Below is a complete CAD model and the FEA for the throw adjustment arm with 50 lbf applied to the shortest throw position. This is the worst case scenario, so if it doesn’t fail here it won’t fail in the other positions.
With the 50 lbf applied to the arm, the maximum stress was ~10k psi which is great news. This component alone is 4 times stronger than it needs to be if you were able to apply 50 lbf to the arm.
I have personally been using this shifter in my 2009 Speed3 for a month now and have nothing but great things to say. Don’t take it from me, though. Here is a quote from a beta tester:
I’m taking a spirited drive today to get a better feel for it. So far I’m enthusiastic about the (extreme) difference. When shifting with the OEM shifter the throw was so long that I spent a lot of effort synchronizing the clutch with the motion of shifting—essentially slipping the clutch while completing the motion of going into gear. With your short throw shifter the entire motion has changed dramatically and all I have to concentrate on is the clutch, and that’s been reduced by ~50%. I just throw it into gear and pop the clutch. It’s so stiff anyway and really likes to engage/disengage near the end when releasing pressure on the pedal that the motion becomes much more fluid. The shifter motion has gotten much tighter and requires (what feels like) more pressure to move between gears, but the motion itself has been reduced so much that it creates a sense of precision and removes (what felt like) sloppiness when using the OEM shifter. I’m sure that adjusting the height & throw from such an extreme position would reduce what I would describe as the rigidity of the shifts, although I intend to continue using it in the position we installed it.
My 2 cents so far. Overall I’d highly recommend.
Hope all is well,
Michael
So what are you waiting for? Take the leap, you won’t be disappointed!

The new CORKSPORT 3rd Gen Mazda 3 shifter bushing set is CAD designed and machined for exacting fitment and are made from billet aluminum and anodized black for a long lasting durable finish.
Over time, shifting gears can cause the soft rubber bushings found at the anchor point of your shifter assembly to deteriorate and fall apart.
The factory OEM bushings are made out of a soft rubber giving you soft and sloppy shifts. The CorkSport shifter bushing set will give you solid shifts and a firm responsiveness.
Designed for easy fitment on the 2014 Mazda 3, 2014+Mazda 6 and 2013+ CX-5 with manual transmissions.
As you are upgrading your Mazdaspeed 3 you start to notice the sharper pulls and unpredictable weight shifting of the engine.
The CorkSport Mazdaspeed 3 Transmission mount will help decrease this movement and give you smoother shifts on the streets or on track use.
Built with black zinc oxide plated steel for a strong frame and a reinforced gusset to extend the life of the bushing.
The CorkSport Mazdaspeed 3 Transmission Mount is CAD-designed and machined with precision. Perfect fitment and extremely rigid to handle the stress from the torque from your engine.
The Rear Motor Mount and the Passenger Side Motor Mount are also great additions to firming up the power plant on your Mazdaspeed 3. With less wheel hop and a less torque steer this trio of mounts will greatly reduce engine movement allowing you to enjoy the Zoom Zoom of your Mazdaspeed 3.
