, also known as blow-off valves (abbreviated to BOVs), are used in turbocharged engines in order to release the high amounts of pressure that have built up inside the system. The valve is connected by a vacuum hose to the intake manifold. When the throttle is closed pressure builds up in the engine and when it reaches a certain point the piston in the valve is automatically operated to allow that pressure to be released until it reaches a comfortable level again. A lot of car owners will buy and fit new dump valves to their car in order to improve the sound of their turbocharged engine, while others will fit them with their primary purpose of helping with pressure release. Either way, cheap dump valves are widely available here at Car Parts 4 Less, along with a vast collection of other performance car parts designed to enhance the look, sound, comfort or performance of your car.
