Motorcraft Ford 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

Silicone anti-drain back valves

• Help prevent oil from draining out of the filter and engine when the engine is not running
• Resist the aging effects that an engine's high heat can cause
• Silicone, available in many Motorcraft® oil filter anti-drain back valves, is superior to nitrile rubber, which can become brittle over time
