Description
Add performance and style while protecting your turbo with the Patent Pending CorkSport Mazdaspeed MZR Bypass Valve. Using an innovative patent pending design utilizing a wave spring, we were able to reduce the spring height of the OEM Bypass Valve by 50%. This size reduction provides the same amount of force while accelerating the speed of the valve. By increasing speed the Bypass Valve effectively increases the life of your turbo by preventing premature wear since the BPV can safely move at speeds 33% faster than stock or other valves. With the extra space allowed by the spring, we were able to increase piston size by over 30%. The increase in size means the bypass valve has a larger venting area, which reduces the time it takes to vent air, allowing larger turbos better venting. Together the smaller size of the spring, and the piston redesign means the body of the valve was reduced. This means you don't have to worry about interference with key parts such as airboxes, custom turbos, intercooler kits, or other modifications that might need the room. Thanks to these innovations the patent-pending CorkSport Mazdaspeed MZR Bypass valve will be a welcome addition to any turbocharged engine bay.

I have enjoyed all my corksport upgrades, and this one is no different! Boost holds firm and releases in a very mature sound, quality is superb, and is a super easy install! Buy this for your MS3!

Very nice piece of equipment, stock-looking (which was a prerequisite for me), and comes with everything needed. Installed in under 5 minutes, since nothing needed modification, moving or altering. In my case, the noise is even more quiet than the stock (though my stock BPV probably had a small leak due to increased boost levels, which caused some noise under certain circumstances). The new BPV holds boosts better, which allows the car to start pulling harder, better and in lower rpms than before. So in my case it was two birds with one stone, fixed the leaking stock BPV and at the same time achieved better performance and boost curves!

So easy to install that I did it on my 15 minute break in the parking lot of my office. This thing is a quick as it is advertised. very responsive. Holds boost very well and looks great. Its got a really nice low profile look and makes a pretty original sound above 10psi. Way better than the Forge sword clanging sound, in my opinion.

Another kick-ass Corksports component. Far better than stock and improves the efficiency of the turbo without a doubt. Not loud and obnoxious at all, just does it's job so you can do yours. Parts like this should have been stock in the first place! Can beat the performance, size, and price for what you get! A+

Just installed this in the driveway today, extremely easy to yourself. Instructions were as always spot on and helpful ;) I had absolutely no idea how bad that plastic oem bypass was leaking...this should be your very 1st purchase performance-wise, don't shop around or look anywhere else just add this to your cart and you can thank me later with corksport points. ;)

Great improvement to the smoothness of the power. The stock unit must have been trash. Power was surging and erratic. Installed this valve and the difference is night and day. So smooth and holds boost strong and steady. Makes driving the car a joy.

Can I combine this with my SRI stage 1 ? Did I absoletely need the accessport ?
Walter Recinos
Definitely a must especially with the SRI & TIP. Mine sounds a little different from the video, might have a small boost leak since don't have the stock gasket on. Maybe? Either way love it and you could definitely feel the difference. Even my girlfriend like it. #everythingcorksport
