I have only run one tank of gas through since installing, but the mpg was better than the tank before. This is the third vehicle I have installed a K&N filter in and am happy with the improvements in performance of the other two.

Appears to be giving me a few more miles per gallon, even around town (33-2200). Used to get 16-17 local on my '04 MDX, now almost 20mpg. On the HWY on a 1100mi trip I make fairly often I was lucky to get 21, this includes the WV mountain! This last trip I got 22.4 on the return which is usually worse than the trip there. Seems also to have increased performance having driven longer, if  that makes sense?

Great product, does not hold moisture like paper filters and keeps out dampness.
