I own a 1997 Dodge Ram 1500 Extended cab 4x4 with a 360ci/5.9 liter V8 automatic. As others have stated, I was also hesitant to buy a K&N because of the $50 price tag and being slightly skeptic of the claims, but I had money to burn that week so I decided to buy it. At first I was very convinced I had wasted my money but none the less I had fun unboxing the filter and installing it along with slapping the K&N sticker on my air cleaner. Then after a week the computer adjusted to it and over the course of a month of driving my truck I had noticed gas mileage being very very good on the highway & city, especially for a truck that'd usually nail down a constant 16-17mpg in stock form.<br /> <br /> Recently I borrowed my truck to my parents and they reported an average of 21mpg on a 1000 mile round trip to pick up an engine! A 4mpg increase on a 360 Dodge truck weighing 6450 lbs loaded down with cargo & passengers none the less over my stock baseline!. I don't know anyone with a stock filter getting anywhere near this mpg with a Dodge!. I believe it has helped my mpg out a lot!.<br /> <br /> As for the power aspect of things, I didn't think much of it, until I had driven other 360 Dodges I had worked on doing tune ups and wondering why they never seemed as fast as mine. The K&N is what I think is delivering that very noticeable difference. Future buyers beware: it may take about 100 miles for the computer to adjust to the new flow of this filter for your butt dyno & pocket book to get the most out of it.<br /> <br /> All things considered, the fact it made any difference at all was a plus in a world of products that don't deliver, but the fact I gained 4mpg and a little more snap to my truck that I can feel is a great thing!. I would highly recommend K&N to anyone looking to get the most out of their vehicle!.

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.

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!!!
