The RENNtech BOV | Blow-Off Valve Adapters are designed as a quick bolt-in solution which are intended to release excessive pressure in high boost occasions.

While releasing the pressure, the RENNtech BOV adapters create the on turbo-charged engines well-known "blow-off" sound.

CNC machined out of 6061-T6 aluminum, the RENNtech BOV adapters are anodized in black and laser-etched. Due to utilizing the OEM electronic diverter valves, the RENNtech BOV adapters will not trigger the Check-Engine light.

The RENNtech BOV Adapters for the newest generation V8 and V6 engine, feature the option to adjust the amount of released pressure, and therefore the volume of the "blow-off" sound. By closing the additional holes with the supplied set screws, the volume of the "blow-off" sound will be decreased.

Each kit comes with 1 BOV adapters, 2 o-rings, 3 stainless steel bolts, and two allen-wrenches. The BOV adapters work perfectly in combination with the RENNtech ECU Upgrade, due to the adjustments to the electronic OEM diverter valves.
