Royal Purple LTD Engine Oil Filter Duramax

The Royal Purple Extended Life Oil Filter has been designed and engineered to match superior particle removal with optimized flow for maximum engine protection along with prolonged filter life. This filter features 100% synthetic micro-glass media to provide superior particle removal. This filter has a 99% filtration efficiency that filters particles as small as 25 microns.

Here are additional features:
•    Shell: Each Royal Purple oil filter features thicker shell material for additional strength and more security against damage from road debris.
•    Metal End Caps: These provide each oil filter with a positive seal for filter element assembly.
•    Center Tube: Prevents filter element collapse.
•    Filter Element: 100% screen-backed synthetic media provides superior  filtration while keeping flow restriction down to a minimum.
•    By-pass Valve: This ensures oil flow in situations of excessive filter element flow restrictions.
•    Steel Backplate: Heavy-gauge steel backplate through each filter for a higher burst strength.
•    Gasket: Premium nitrile rubber with special lubricity compound reduces torque during both installation and removal.
•    Silicone Anti-Drain Back Valve: Prevents dry starts by eliminating oil drain-back during shutdown. The anti-drown back valve is made of silicone which outperforms and will outlast most standard nitrile rubber in both extreme hot and cold temperatures.
