Bought this for my 2016 Nissan Frontier S 2.5L. Truck is definately happier and has a more predictable throttle response. Definately no power gain, but the engine seems happy and the induction noise is more pleasing than the nasally bog that the stock filter caused.

K&N are by far the Best Air Filters on the market today. Most of the general public doesn't know but the US Military uses K&N air filters on the Black Hawk and Apache Helicopters as I believe all of the Helicopter Assets. Why, because they are the best you can get.
