Mustang UPR Crankcase Breather Kit
Free up horsepower in your 2001-2017 Mustang with this UPR crankcase breather kit! UPR designed this kit to remove unwanted crankcase pressure underneath your pistons during their down stroke. Utilizing a one-way check ball valve, this breather kit keeps unwanted air from entering your crankcase. Four internal baffles control oil as this kit takes the place of your factory oil cap. UPR constructs the body of the valve with CNC machined billet aluminum for strength and durability that lasts. A high-flow air filter clamps to the top of the valve, while the valve presses into your crankcase, for a quick and easy installation!
