Call me a sucker too. Many years ago I bought a K&N for my Honda Accord - and then my first Firefly - hoping it would be better for fuel economy. Wishful thinking on my part before digging deeper into the issue. I later reinstalled the OEM filter in and sold the K&N to someone else.

It's been a while since I checked the K&N site, and here's their official position: "we do not go so far as to make a general claim that our air filters and intake systems will provide an increase in mileage."

If they did, they'd likely face a government lawsuit for misleading advertising/unsubstantiated claims.

Anyway, let us know if/when you get some fuel economy instrumentation. You won't regret it.
