K&N HP-1004 Oil Filter

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.

Always great products

Always good products from K&N. Does the job.

Does the job well.

I decided to do the oil change myself only to find out that the dealer had an incompatible filter and the oil was muddy. The engine now seems to be a bit more smoother and the temps a good amount lower. Always make sure your oil filter has the check valve. Will always go with K&N.

K&N oil filter

This is a great addition to go with amsoil for every service

Last Piece to the puzzle

This filter was the final piece to my puzzle of getting my car back up & running.

Best filter

Filters great, and easier to work with than the stubby stock one
