Subaru WRX Turbo By Pass Valve - COBB - LF - 15-18. A direct-fit, recirculating BPV that delivers consistent boost relief and crisp throttle response for your FA20 WRX.

Built for the factory turbo system, the COBB LF replaces the aging stock valve with a durable, recirculating unit that resists leakage under higher boost. It preserves MAF-based fueling and quiet operation while sharpening boost recovery between shifts. Compatible with 2015-2018 WRX and 2014-2018 Forester XT, it mounts in the OE location and connects to the factory recirc hose for straightforward, bolt-on fitment.

Features

• Direct-fit for 2015-2018 WRX; also fits 2014-2018 FXT
• Recirculating design for stable drivability
• Improved boost control versus tired factory valves
• OE-location install with factory hose interfaces
