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.

As usual I received a quality filter at a fair price. Installed it in my newly acquired 98 Dodge Ram 1500. Real or imagined, it breathes better and runs stronger. T

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!.

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.

Changed the filter over in about 10 mins. Took the car out for a test and the difference was noticeable straight away. Much better acceleration. Previously it felt like I was towing a 40 ton trailer. Well worth the change.

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

Ordered twice from K&N once for my 98 Eclipse (short air intake system) and my 2002 ZX6R. Both products made me love K&N. This time I bought an air filter for my 2001 Jeep Cherokee and its great and easy to install. I always recommend K&N to my friends.

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. :)
