I install K&N products on every mode of transportation, I have ever owned.. 2 MPG better after install and throttle response is always better.

I Replaced the original filter which was past over due. This Afe filter has sure increased the gas mileage by I would say a couple of miles to a gallon. Highly recommend over K&N which is oil based.
