Subaru WRX Bypass Valve - GrimmSpeed - V2 - Red - 2015-2021. A direct-fit, fully recirculating bypass valve engineered for consistent boost control and dependable performance on FA20-powered WRX models.

The GrimmSpeed V2 features a precision-machined aluminum body and an O-ring sealed piston for quick response and long-term durability.
