The Royal Purple Filter 20-820 is built smarter and stronger therefore causes it to outperform in the toughest conditions. Royal Purple manufactures only one type of oil filter – the super-premium Extended Life Oil Filter, designed to perform as the best oil filter available. This filter is engineered to match superior particle removal with optimized flow thus maximum engine protection and filter life.
THE BEST OIL FILTERS
The 100% synthetic micro-glass media we use to make Extended Life filters provides superior particle removal – with 99% filtration efficiency at as small as 25 microns. As a result the difference between Royal Purple and conventional oil filters is staggering.
ROYAL PURPLE FILTER 20-820 DESIGN AND CONSTRUCTION ADVANTAGES
Each Royal Purple 20-820 oil filter features thicker shell material, thus extra strength and extra security against puncture from road debris.
Provide each oil filter with a positive seal for filter element assembly.
Designed to prevent filter element collapse.
100% screen-backed synthetic media provides superior filtration while keeping flow restriction low.
The Royal Purple Filter 20-820 is engineered to ensure oil flow in situations of excessive filter element flow restriction.
Due to the heavy-gauge steel backplate through each filter, our filter has higher burst strength.
Premium nitrile rubber with special lubricity compound reduces torque during installation and removal.
SILICONE ANTI-DRAIN BACK VALVE
The anti-drain back valve is made of silicone, which outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures. The Royal Purple Filter 20-820 prevents dry starts by eliminating oil drain-back during shutdown.
