    GFB Respons Blow Off Valve

    Atmosphere venting BOV won’t work on your car? Try a GFB Respons Blow Off Valve – you’ll be surprised!

    On the surface, the GFB Respons BOV look like just another dual-port blow-off valve, but the GFB Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the GFB Respons allows you to precisely control how much air vents from each of the two outlets.

    Why is this so important? Two key reasons:

    Adjust how loud the blow-off sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it ANYWHERE in between to suit your preference.

    Get a blow-off sound WITHOUT causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF).
