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 second vehicle I have owned where I have purchased and installed a K&N washable filter. As before, the filter was easy to install and fit perfectly. While I have no way of knowing for sure or proving it, I think/feel the engine runs smoother and has more pick-up. I like the fact that I can wash and re-charge the filter (saves on landfill and I think is environmentally friendlier than disposable filters) and can do it whenever I want without the expense of a new filter. If the truck was new I would have invested in a K&N Cold Air Intake system. They are outrageously good!!!

This filter installed very easy on my 2001 dodge 1500 quad cab truck with a 360 magnum. I noticed the power difference right away and my gas mileage also improved. Would highly recommend this upgrade to anyone.

My 1999 Dodge Ram 1500 4x4 has the 5.9 litre V8 and I average 15.5 mpg. I have a factory cold air intake so I bought the K&N drop in air filter for it. After installing it I went on a short drive around town. I drove around 70 miles and my gas gauge needle never moved,showing me I for sure made a good investment by getting my K&N filter. My truck has 136,000 miles on it There are no oil leaks, it doesn't use oil and it is still a beast with 350 foot pounds of stump pulling power.

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.
