BMS Blow Off Valve (BOV) Adapter for 2019+ Mercedes Benz M139L 2.0L I4 Turbo

The Burger Motorsports Blow Off Valve (BOV) mounts between the OE bypass solenoid and the vehicle, causing the unused charge air to vent to the atmosphere giving off the desired "Pshhhh" blow-off sound all turbo owners love.

Easy install. Remove the factory bypass solenoid, place the BMS BOV in between, and reattach it to the vehicle with the supplied extended bolts.

CNC machined out of lightweight billet aluminum and anodized black so they last the life of your vehicle. All required hardware included.
