Overview

It features a patent-pending design with a wave spring that reduces spring height by 50%, allowing for faster valve speed and improved turbo lifespan.

Show original supplier description
This patent-pending bypass valve (BPV) utilizes an innovative wave spring design, reducing the spring height by 50% compared to OEM units. This significant reduction allows the valve to operate 33% faster than stock, which helps prevent premature turbo wear and effectively extends the turbo's lifespan. Further enhancing its performance, the MZR Bypass Valve features a piston size increase of over 30%. This larger piston provides a greater venting area, leading to quicker air release and improved performance, especially for vehicles equipped with larger turbos. The compact design, a result of the smaller spring and revised piston, minimizes interference with other engine bay components such as airboxes, custom turbo setups, and intercooler kits. Constructed from billet aluminum, this bypass valve offers a lightweight yet durable build. Installation is estimated to take approximately 1 hour with a difficulty rating of 1 out of 5. The product comes with a 2-year limited warranty, full-color installation instructions, all necessary hardware, and access to CorkSport's telephone support. Fitment is specifically for the Mazdaspeed 3, Mazdaspeed 6, and Mazda CX7 models.
