CTS Turbo MK8 GTI EVO4 BOV (Blow Off Valve) Kit

CTS Turbo's Atmospheric Blow-Off Valve kit for the EVO4 MK8 GTI is a billet-construction valve that's fully serviceable and built to integrate seamlessly with all factory electronics. It's plug-and-play with no wiring extensions and won't trigger a check engine light.

It replaces the failure-prone factory plastic unit — the one susceptible to torn diaphragms, cracked plastic, and electrical malfunctions. The robust piston design guarantees longevity, easy installation, full serviceability, a great auditory experience, and excellent value. Compact and slightly shorter than stock, it fits cleanly into the tight engine bay for reliability, performance, and that signature turbo sound.
