Part Number: BOV:09.0388.TWIN Category:


Additional Information

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 full set comes with 2 BOV adapters, 4 o-rings, 6 stainless steel bolts and an allen-wrench. The BOV adapters work perfectly in combination with the RENNtech ECU Upgrade, due to the adjustments to the electronic OEM diverter valves.
