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.

1997 F350 8ft crew 7.5 gasser auto, single wheel, pulls 8000lbs of toy hauler and firewood. Only add is a B&M Trans Switch assembly and a multi quart trans pan and lil dents and scratches all the kids swear makes it faster now dad. The truck has 100k miles and we just installed new fuel pumps it needed she was still not acting like a big block motor, had torque but just wasent producing that big block  power we all expect. After installing the C.A.R.B. Approved K&N 52-2516 FIPK and replacing the stock muffler with a 2 chamber (Brand) we now feel it performs better than when it was new. The increased throttle response and report really WOWED us and she pulls like never before, we just couldn't be happier. DO NOT be the ********* we were and try the metric nut on the sae stud located on the filters chrome end, the sae nut is included and a quick check before wrenching is all it takes for a very clean and sturdy install. Check the 4 mass air flow adapter plate nuts and bolts the filter mounts to also, as we found they loosened up when the new assembly went through several heat cycles, once retightened they have remained in spec. We would indeed recommend this kit to any 460 gas drivers out there to spice up the performance and sound of their old ford. We are indeed considering the blue pre filter to spice up under the hood and prolong the filter use between servicing. What more can be said except, have you ordered it yet? no, why not. lol

Ordered for my ford f150 because i like the way it's made, found I can now buy it in my local walmart store.

I didnt think it would make that much of a difference. My 02 Ford F150 4.6 has been having issues with power and it was dogging out on me. I went for a drive after i installed it and WOW It sounds so mean and the power is unbelievable. I wasnt expecting that much of an increase. Ill have to drive it more to see if the problems went away. I struggle up the same hill every day on the way home from work when i just took it out i accelerated faster up the hill than i did before on flat ground i fell in love with my truck all over again. Thank you K&N you guys are amazing I am forever grateful i am going to tell everyone i know about your product.
