Lance Rizzuto, Williamsburg, Virginia
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!!!

Filter made a positive improvement, my old air filter did not look dirty either.

No picture of anything fancy, just an older 3/4 ton Dodge Ram that works its rear off in dusty conditions. A perfect fit, it even looks cool.

My info center computer states that my mpg went from 30.8 to 31.5 This is with appox. 750 miles driven. I have no info on the horsepower. But I assume it has similar positive results.

Not the cheapest, but definitely the best. In my 13 year old diesel Volvo, I put a new K&N air filter and it got all the lost horsepowers back. :)
