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.

Absolutely love the chrome-trimmed K&N air filter! It adds a lot to the overall excellent look and performance of my old but clean 88 Porsche 911. Thanks for providing such a great product, timely and inexpensively. I looked in all the auto parts stores in Albuquerque, but they had nothing comparable for that price in stock. I appreciate being able to order harder-to-find specialty items online at less than retail. Thanks!

Nice product!  I own a 2001 SAAB 9-5 AERO with 128,000 miles and just purchased my first K & N filter...very impressed.  After 2 tanks of gas I'm getting about 2 to 3 more MPG's (city) and the performance...wow!  Even though I never believed it...Aeros are reportedly faster than a stock porsche 911 of the same year.  However, after replacing with the K & N filter, I'm a believer!  Not sure how much horsepower I've gained but the car is much much more responsive and will flat put you back in your seat if you punch it!  I never thought an air filter would make that big of a difference, but it did.

I have now received the oil and air filters for all my cars- Range Rover Sport Supercharged, Jeep Grand Cherokee Limited, Jeep Rubicon, Mercedes Benz E430 and Porsche Cayenne S (only air filters for this one). I have used your products for a long time and am fully satisfied, so I keep the oil filters in stock for regular oil changes.
