CTS TURBO BMW N20 BOV (BLOW OFF VALVE) KIT
CTS Turbo's Atmospheric Blow-Off Valve kit for N20 BMW engines is a serviceable billet unit that replaces the factory plastic valve prone to torn diaphragms, cracked plastic, and electrical failures. It runs with all factory electronics and won't trigger a check engine light.
The piston design means long life, easy installation, full serviceability, great sound, and great value. It's slightly shorter than stock and tucks neatly into the tight N20 engine bay. Installation does not require removing the factory turbocharger — figure 60-120 minutes depending on your experience.
Note: if your car has an electric wastegate, you'll need a boost tap to install this BOV. We recommend the P3Cars boost tap.
