The Mopar MO-899 Oil Filters are designed using Chrysler engineering specifications, which means they can help maintain peak engine efficiency and performance. The internally lubricated seal gasket provides better torque removal and easy replacement. The anti-drain back valve helps prevent dry starts. The high heat-resistant “nitriles” in the valve help improve functionality and anti-drain back performance. The filter is engineered with high dirt retention capacity for longer service intervals and severe driving conditions and its adhesive-filled double lock seam can withstand pressures up to 300psi. The fluted case allows easy installation and removal.
