This bolt on adapter allows you to replace both your flimsy diverter valves with a single Tial flange blow off valve. Benefits include better sound, a unique look under the hood, and the potential to hold more boost between shifts. Includes block off caps for the intake hoses. Reuses factory o-rings for a leak free factory like installation.
Adapter can be purchased ala-cart or with an authentic Tial BOV. We suggest using the Tial BLACK (6psi) spring based on our testing. Running a too heavy spring may prevent the BOV from opening properly.
