Detailed Features and Specifications

The PO5288EX oil filter features a 4.04-inch height and a 2.99-inch outer diameter at the bottom, fitting precisely in designated engine compartments. Its synthetic blend media balances filtration efficiency and flow rate, capturing harmful particles while maintaining oil circulation. The anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during startup. The bypass relief valve activates at 20 psi, allowing oil to bypass the filter element if it becomes clogged, ensuring continuous lubrication. The silicone gasket, with a thickness of 0.21 inches and inside/outside diameters of 2.51 and 2.89 inches respectively, provides a reliable seal to prevent leaks.
