Nailer, he said this K&N was for a Compass!
Joking aside, K&N's don't help at all with fuel economy or performance, they can save money over paper filters. In 100,000 miles of driving, the K&N will cost less to re-use, than buying disposables.

You're likely to see no difference, but if there is any to be had, it will only come at wide-open-throttle.
In any other position, your filter isn't the bottle-neck in the ability of the car to get air.
