I've used K&N filters in my cars and truck, and have always been totally satisfied. I would recommend them to anyone for the last filter you will ever need. Simple to use and recharge, and saves you money at the same time. Be a winner, use K&N.

We installed our new K&N air filter. I didn't expect much of anything over the factory air filter but to my surprise, not only was there an immediate change in throttle response and torque, but we also have been enjoying the extra MPG since install. Well worth it. Thank you K&N.

I have used your air filters in the past and found them to perform very well. I put this filter in my 2012 Honda Accord and it seems to have improved the performance. I am considering purchasing your air filter system but, I am a little worried about the installation.

Seems to be working well but dislike the reduction of gas mileage.
