Royal Purple® premium oil filters provide superior filtration and flow, outstanding particulate capacity and heavy duty construction for cleaner oil and longer filter life.

Slide

Shell

A thick, heavy exterior shell provides extra security against puncture from road debris.

Filter Element

100% synthetic filtration media with steel screen backing provides superior filtration, low restriction to flow and high particulate capacity.

Steel Backplate

Heavy gauge steel provides up to twice the burst strength of ordinary filters.

Metal End-Caps

Provides rigid support for filtration media enhancing internal sealing.

Metal Center Tube

Metal construction prevents filter element collapse.

Bypass Valve

Ensures oil flow in situations of excessive filter element flow restriction.

Silicone Anti-Drainback Valve

Prevents dry starts by limiting oil drain back after shutdown. Silicone outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures.

Gasket

Premium nitrile rubber and special lubricity compounds reduce torque during installation and removal.

Royal Purple filters are available at many leading suppliers of automotive products.

Filter media Comparison

Filter_Cellulose_Media

Magnification of 250x, photo shows conventional cellulose filtration fibers. The spaces allow larger particles to pass through to your engine.

Filter_Glass_Media

Royal Purple’s state-of-the-art synthetic filtration media provides greater filtration efficiency and particulate capacity while minimizing flow restriction.

Average beta rating based on ISO 4548-12 multi-pass test methods:

  • ß25 = 100 (at 25 or greater micron, media is 99% efficient.)
  • ß20 = 75 (at 20 or greater micron, media is 98.7% efficient. Also considered absolute rating.)
  • ß10 = 5 (at 10 micron or greater, media is 80% efficient.)
