I use a K & N air filter in my Mercedes C250cgi Turbo. There is a noticeable difference in performance and drivability compared to the standard Mercedes air filter. Just a shame they don't make one for a Honda Odyssey 2.4.

Go ahead and use this on your customer feedback page:  Last summer I bought one of your air filters for my 2003 Honda Pilot, a perfect drop in fit.  Right away I noticed the engine ran quieter and much smoother.  Took it out on the road and, wow, what a difference in power.  I'm not talking a lot of difference, but noticable. I figured this filter increased my gas milage between 1-2 mpg.  Today I went out and ordered a filter for my 2011 Hyundai Sonata SE.  I expect similar results and will continue to buy your products for all my vehicles.

When looking for a van, I decided on the 2007 Honda Odyssey EX-L with the VCM (variable cylinder management). This is supposed to provide better fuel economy. The sticker read 19mpg for the city and 26 for freeway driving. I drive very conservatively (especially with gas prices the way they are) and I was not getting what Honda said was average even after 5K. I was getting about 15-16mpg in town and 22mpg on the freeway. Enter the K&N air filter. As soon as I checked my mpg again I was getting 18-19mpg in town (now 20mpg) and 25mpg on the freeway (now, sometimes 26 or 27). Thank you K&N for helping me to achieve what Honda said I'm suppose to get with cheap standard air filter. Now I'm looking at getting one for my 2008 VW Passat wagon.
