This is a great product and is very easy to install. I have a lot faster throttle response and you can really hear the difference under the hood. A great company to deal with, super fast shipping and very low prices.

My purpose of installing this on my truck was to try to improve the mileage. I can monitor this closely with the trucks built in computer and after 20K plus use I can report it made no improvement. If you are into more sound and cab noise it does that but for me that is a negative. If I use my imagination I might have improved throttle response and a maybe a bit more hp but I have no scientific proof of that. After running the K&N for 20K I added a new MBPR exhaust system and I have run that for around 10K and I have a slight improvement in mileage (1 mpg). What I can not say is if the mileage improvement with the exhaust system would have occurred without the installation of the K&N with it. I hope that if I put 100k more on the truck that I will recoup my investment with the minor mileage increase.
