Motorcraft FL820S Silicone Valve Oil Filter

Helps protect against engine wear by screening out abrasives, such as carbon, sand, dust and bits of metal before they can get into your oil
Pressure-relief valves help minimize the chance of contaminated oil circulating back into the engine
Pressure-relief valves also help maintain the supply of oil to the engine under extreme cold conditions or if the filter gets clogged
Steel cases are "ironed" for a precise fit, fluted to ease removal and painted to resist rust
Efficient filter media offers increased dirt-collecting capability and ability to capture more engine-harming particles
