COBB LF Bypass Valve Mitsubishi Lancer Evolution X (CZ4A) / Lancer Ralliart (CJ)

COBB LF Bypass Valve - Mitsubishi Lancer Evolution X (CZ4A) / Lancer Ralliart (CJ)

The COBB LF BPV replaces the factory bypass valve on the Mitsubishi Lancer Evolution X and Lancer Ralliart. It is compact and lightweight, holds very high boost without leaking, and its low-inertia internals respond quickly. The updated design has 30% less control volume for very fast venting, a larger piston seal and a stiffer spring setup that adds clamping force at peak boost.
