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.
