Bypass Valve RED - Subaru 08-14 WRX 05-09 LGT

Redesigned from the ground up, this valve from GrimmSpeed addresses the limitations of the previous version, improving manufacturability, performance, and reliability while maintaining the high-quality look and feel GrimmSpeed is known for. It features a redesigned internal piston to eliminate potential failure points from V1, optimized spring tension for superior response, and an an updated main body design for a cleaner CNC finish. The lightweight hard aluminum piston replaces brass for faster valve response, and the inspection port has been removed for a more streamlined design. It is built to hold double the pressure of stock bypass valves while remaining leak-free.
