GM Genuine Parts Power Brake Booster Check Valves are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These valves function as a one-way valve that ensures air does not enter the vacuum booster when the engine is turned off or if there is a leak in the vacuum hose. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
