Royal Purple oil filters provide superior particle removal, high-performance and optimized flow characteristics for maximum performance and longer filter life.

Each Filter features:

Royal Purple’s filter media uses the latest technology filtration system that filters out particles as small as 25 microns.

  • 100% synthetic micro-glass media for superior particle removal with 99% filtration efficiency at 25 microns. See the difference

 

Conventional Fiber
Magnification of 250x, photo shows conventional cellulose filtration fibers. The spaces allow larger particles to pass through to your engine.
Royal Purple Better Oil Filter Fiber
Royal Purple’s filter media uses the latest technology filtration system that filters out particles as small as 25 microns.
  • High-performance silicone anti-drain back valve that prevents dry starts, even in extreme conditions
  • Extra heavy duty rubber base gasket that ensures a leak-free seal.
  • An ultra-strength filter housing endures higher burst strength than conventional filters.

Performance Advantages

 

Shell

Thicker shell material for extra strength. The heavier shell provides extra security against puncture from road debris.

Metal End-Caps

Provides 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 low.

By-pass Valve

The by-pass valve is designed to insure oil flow in situations of excessive filter element flow restriction.

Steel Backplate

Heavy guage steel for higher burst strength

Gasket

Premium nitrile rubber with special lubricity compound to reduce torque during installation and removal.

Silicone Anti-drain Back Valve

Prevents dry starts by eliminating oil drain back during shutdown through the use of a silicone anti-drain back valve. Silicone outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures.
