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.

Christopher Stauffer, Enterprise, Oregon
Absolutely fantastic replacement over the original paper filter... you can hear the difference! Car breaths better and has noticeable improvement in fuel economy (averaged 30-40mpg before, now more like 35-40mpg). Thanks.

Seems to be a high quality air filter.
