Thicker shell material for extra strength. The heavier shell provides extra security against puncture from road debris.
Provides positive seal for filter element assembly.
Prevents filter element collapse.
100% screen-backed synthetic media provides superior filtration while keeping flow restriction low.
The by-pass valve is designed to insure oil flow in situations of excessive filter element flow restriction. Steel Backplate
Heavy gauge steel for higher burst strength.
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
Royal Purple oil filters provide superior particle removal, high-performance and optimised flow characteristics for maximum performance and longer filter life.
Each Filter features:
100% synthetic micro-glass media for superior particle removal with 99% filtration efficiency at 25 microns. See the difference!
Both photos are taken at a magnification of 250x. The photo on the left uses conventional cellulose filtration fibers. The spaces allow larger particles to pass through to your engine. The photo on the right, of Royal Purple's filter media, uses the latest technology filtration system which filters out particles as small as 25mc.
A high-performance silicone anti-drain back valve that prevents dry starts, even in extreme conditions.
An extra heavy duty rubber base gasket that ensures a leak-free seal.
Ultra-strength filter housing endures higher burst strength than conventional filters.
