Works great, and the engine certainly feels quicker on its toes! All valuable for the added strain of big roof loads. Had a K&N on my last ride too, and they really give you bang for the buck! The filter's ridges don't run the same direction as factory, and the filter is only almost square, so installation is tricky till you figure that out!

Install couldn't be easier. Post install there is noticable extra power when accelerating to pass at freeway speed. No figment of the imagination as my wife and dad also noticed (and didn't know I put in a new filter). Getting an extra 3 miles per gallon highway haven't noticed an increase in city MPG.
