I have had many K&N filters. This one was for a jeep that for the first time towed a motorcycle trailer from NJ to Williamsburg Va. The Jeep ran hot towing so one of the few things I could do while do on Vacation was to get a K&N filter to help for the trip home. K&N got it to my resort the next day. It added enough power that I ran about 20° cooler. K&N, Good Stuff. Worth the price just on that one trip.

This is the third vehicle in which I've installed a K&N filter - always a great investment.

Installed on my 2000 Jeep XJ I6. Engine definitely feels a bit more responsive after installing this filter. Gas mileage not totally conclusive as of yet, but need more time - looks to be slightly improved (5?). And I'll never have to buy another air filter I'd say this is totally worth it for a vehicle you plan to keep around for 100k+ miles.
