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.

K&N is the ONLY way to go when it comes to air filters.

The air filter was easy to install on my 2013 Nissan Altima. It seems that I am getting an additional mile per gallon since it was installed. So far, I am very pleased with K&N air filters.
