Cobb Bypass Valve for 02-07 WRX, 04-21 STI, 06-08 Forester XT
The COBB LF BPV is a compact and lightweight by-pass valve designed to hold extremely high boost pressure without leaking. With an updated design that reduces control volume by 30%, this valve enables rapid venting of boost when actuated. Its precision manufacturing ensures a compact profile that fits seamlessly into tight engine bays, making it an ideal choice for performance-driven applications. The innovative Banjo-fitting vacuum port allows 360-degree adjustability for hose routing, simplifying installation and reducing potential leak points compared to traditional NPT ports.
This enhanced design incorporates a piston o-ring seal that is twice the diameter of the previous version, offering improved seal compression and reduced wear over time. The LF BPV eliminates the need for adjustable spring seats, as the updated spring and seal design deliver a 60% increase in clamping force at peak boost while maintaining excellent performance at idle and during transient loads. Its lightweight components minimize inertia, ensuring faster response times compared to heavier alternatives.
The COBB LF BPV delivers exceptional performance, durability, and ease of use, making it a standout solution for optimizing your vehicle's boost control system.
