Best air filter so far. Everyone in my car club have been using K&N filters in their classic cars and now have me hooked. Especially the fact that I can clean my filter and not have to spend money for new ones.

My first k&n air filter was a stock replacement in a 1991 Chevy caprice with the 305 v8. When I got the car, I calculated a highway mileage of 24mpg. My caprice had no modifications whatsoever. During the 7 years I owned it I put a performance chip in it, gutted the catalytic converter, installed a high flow muffler, and put a K&N filter in it. Afterward I noticed near instant throttle response, was able to make just about any loud dodge truck eat my dust, and got a real world 27 mpg on the highway. I have since traded the caprice in for my first 4wd vehicle: a 2006 gmc sierra 1500 with the 5.3 v8 and z71off road package. The first mod I've done to my new truck is put a stock replacement style K&N filter in it. I chose it over a cold air intake because the air box is covered up and bottom and I have got water/mud on top of the airbox. I can't say much as to a very noticeable power change in my truck, but I have noticed a better sounds inside the cab and a real world gas mileage change from 18.6 on the highway to an even 20.0mpg. I got this mileage during a 960 mile trip over two 11,000+ ft mountain passes. I really like your product as both a cost-saver (you only buy one) and an efficiency booster.

I honestly don't believe there is a better upgrade than this. It got my 1992 Chevy Caprice Wagon running happy. Also I love the fact it is cleanable with the K&N Recharger Kit. I want everything K&N. Thank you K&N! HURA from a military veteran.Thank you for your service!
