I notice a small bit of horsepower change but not much. Gas mileage is a little bit better and it has quieted down the engine upon exceleration. I like it.

I have been using K&N filters for over 20 years and have always been completely satisfied.  
Scott Vetor, Belle River, Canada
Love these filters This is my third filter which is in my wife's brand new Nissan Altima. I also have one in my 2014 Sierra SLT pickup, and previously had one in my 2002 Sierra. By purchasing a large container of oil, and cleaner I will save a lot of money in the long run. The filters wash up easily and the fit in the air filter compartment of both vehicles is flawless. Would highly recommend these filters if you plan to own a vehicle for several years.
