Blow Off Valves (BOVs) are lifesavers for turbocharged engines. They prevent damaging backflow of compressed air when the throttle closes. They come in two flavors: diverter valves (recirculate pressure) or atmospheric BOVs (vent pressure with a cool sound). Some BOVs are even adjustable for customized performance. Made from tough materials like aluminum, BOVs are built to handle the pressure of a turbo engine.
