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.

Review part HP-4001
Tuesday, November 25, 2014 - Part HP-4001
The filter went on just fine, although a one inch socket wasn't the easiest to come by in my collection with smaller than a 1/2 drive wrench. The filter itself will probably do fine. I've had good luck in the past with K&N products.
