Originally developed for demanding race applications, K&N's Premium Wrench-Off Oil Filter has become a favorite among consumers for its durability and easy removal. Most of our automotive and marine oil filters come with a 1” nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. To satisfy the demands of racers, our oil filter has many features over and above the requirements of most vehicles. We use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The drilled hole on the nut provides for safety wire attachment. Our oil filters also use a resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration.

Product Reviews      Review part HP-2004

 A little bigger than a FRAM and 3 times as big as a MotorCraft. The only filters for a 5.7 Hemi in my town are Purolator, and I've never tried one. I will use K&N racing filters for my Hemi!
Tory Babcock, Torrington, Wyoming
 I use K&N products in all of my vehicles. Great product. I enjoyed the virtual tour of your facility.

 Filter is used on 2007 Charger SRT8 Superbee w/ 0-40 Mobile One synthetic. I used this same upgraded filter on my 2004 Pontiac GTO w/ 5-30 Mobile One. It gives me re-assurance of maximum filteration capability and good service life for my 6k/mile intervals.
Christopher Denton, San Jose, California
 I received my filter in a timely manner. I installed it on my Glasair Aircraft. I am confident I used the best quality filter I could find.

 Service on this and previous orders has been outstanding . Product has performed as advertised .
John Blackburn, New Mexico
 Tough filter. Keeps oil clean, easy takeing off. Only problem is the filter loosens up slightly when on.
