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.

Though I've been using K&N Air filter since sometime in the 90's and wouldn't use any other air filter. I started using the HP-4005 Oil Filter for my first time on my 2015 Super Duty 6.7L Diesel. I just completed my 8th oil change using the K&N Oil filter and working in the petro industry, I took a quart of oil from the 7th oil change to a friend at work. He performed some testing on both the oil for possible break downs as well as he filtered the oil checking the size & amount of particulates in the oil that ran through the filter. It appears that the K&N Oil filter performs exactly as it should. I was told that there were no-traceable amounts of particulates in the oil and that almost always there are when testing other filters. It was the first time my friend has performed any testing on oil ran through the K&N, but stated he's changing from [brand] filter to the K&N in the future. Also, the filter is simple to remove with a socket or combination wrench.
