I was skeptical purchasing this product but decided to give it a shot anyway and am glad I did. Received the intake kit for my 2002 Dodge Ram 2500 with a 5.9 diesel motor. Installation was a breeze. It took approximately 35 minutes from start to finish to install. Took the truck for a test drive and noticed an improvement in the acceleration. It has been a few weeks since I installed this product and am now seeing a small increase in fuel mileage. A bit pricey but a great product that I would recommend to others.

Let me start off by saying I have been a diesel mechanic for almost 20 years. I have a 2004 Dodge Ram 2500 with a Cummins. I have been using a name brand filter for my truck and the fleet that I manage. I am always skeptical of after market products. One of the biggest problems with low power in a diesel is a clogged filter. I replace a lot of filters in my pick-up. Even thought the air restriction gauge shows the filter is still good, I usually replace the filter as soon as it starts to pull down. I always get a lot of black smoke when I get on the gas with my truck. The turbo is slow to wind up and the acceleration is lack luster. I wanted to do something about it, without spending a lot of money. I did my research online read the reviews both good and bad. I also spent a lot of time on the phone with K&N asking probably more than my fair share of questions. They assured me that their filter with not harm the engine and will improve the performance. After a lot of thought I decided to get just the filter. When I opened the box, I noticed the filter was a lot bigger and conned shaped, not a flat panel like the stock filter. It was much bigger. It fit perfectly in the factory air box.I started my truck and stepped on the gas. I immediately noticed the lag in the turbo was almost gone and that was just sitting there. I was eager to try it out on the road. Took the truck out and stepped on the gas. The black smoke was cut in half. The turbo wound up much faster and you could hear the whistle of the turbo. I don't know if it will affect the MPG yet, but I can tell you just cutting the black smoke down is enough for me. Anything above that is a bonus. My only regret is that I didn't buy it sooner. I am ordering one for my 2012 Chevy Sonic. I am also thinking now that maybe I should have bought the cold air intake for my truck. You have a customer for life. I am talking to K&N about filters for the Class 8 trucks in the fleet now. I been in this industry for a long time, not too many things impress me anymore. I am beyond impressed with your product. I had been missing out for a long time on a great product.

I replaced the OEM filter that came with the [brand] carbon fiber case high performance filter system I run on my 2002 Cyclone M2.I don't believe there is anything better. I use K&N oil & air filters on almost everything I own, (two bikes, one Ram 3500 P/U, a Mitsubishi compact diesel tractor and three V-8's, one Pontiac, one Ford and one Chevrolet.
