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.

This Oil filter is the best I have used on my truck, The welded on nut really helps out when the filter just doesn't want to come off by hand and the high flow of it just helps oil deliver throughout the engine faster than any other filter I have used in the past. I Plan to keep on using K&N's Products as primary choice until the end

Nice solid product. Just fitted to my '97 Cherokee Sport. Nice to have the 1 nut on the top too.

The old filter that I replaced had very thin metal and was overtightened. The filter was very hard to remove and was quite damaged in the process. I will always use HP filters from now on.

What can I say? It's an oil filter by K&N. Should be a lot easier to replace with bolt on filter.
