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 inch 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.

Great product. Just did an oil change (12 qts) & removing the old filter was a real pain. Had to take off the fender skirt to access the filter from the passenger side over the tire with giant channel locks. With the K&N filter having the bolt on the bottom, the next oil change will be a breeze. It was easy to install - it has a good beat & it's easy to dance too. Outstanding product - easy on-line ordering too. Happy Customer here!

The HP-4003 high flow filter in diesel application is a superior filter to other filters because of superior oil flow compared to these other filters.In my opinion you do not want to use a reusable filter in diesel applications. The HP-4003 filter is one step below a reuseable filter in high flow application.

Haven't installed it, so can't rate the filter. But your service was great. Very punctual and correct.
