Running this filter in my Honda Accord for over 10 years. Improved throttle response is the most noticeable benefit and better mpg.

This product is the best I've ever used. I have one in my Rodeo for years, and perform very well. Thanks K&N.

I installed the air filter when I changed oil a couple of weeks ago. I have noticed that the car gets better fuel economy and runs better. Very pleased.
