Peterson Fluid Systems one-way pop-off valves install on your valve cover, providing a safety relief mechanism in the event of positive crankcase pressure (only 2 psi to trigger). They're available in either direct valve cover mount or inline. The valves feature CNC-machined billet aluminum construction for light weight and durability—and are offered with or without a high-quality filter element. Choose the size, style, and anodized color you prefer. Order the one-way pop-off by Peterson Fluid Systems designed for your valve cover ventilation needs.
