MIA's Description

The Grimmspeed V2 Bypass Valve is a redesigned bypass valve with improved manufacturability, performance, and reliability. It features a redesigned internal piston to eliminate potential failure points, optimized spring tension for superior response, and an updated main body design for a cleaner CNC finish. The lightweight hard aluminum piston replaces brass for faster valve response. This valve is built to hold double the pressure of stock bypass valves while remaining leak-free.
