Keep your power brakes working properly with a new vacuum check valve! The valve inserts into the booster and connects to a vacuum source on the intake manifold. OPGI offers an original style plastic replacement or a chromed plastic version for a custom touch. Also available is the check valve rubber grommet, which is often weathered and cracked due to engine heat. Replace yours today!
