Since adding the air filter I've notice a slight improvement in gas mileage.

Haven't noticed much of a difference in performance or mileage, but didn't really expect to. I mainly bought this for the money it would save in the long run. At $20 a pop for paper filters it will pay for itself in no time. There's not much you can do to today's engines short of retuning to squeeze out much more performance or efficiency. So don't expect miracles. But a quality dry filter can't hurt.
