Has anyone REALLY done a Mpg test after they have done a mod? Like adding a K&N, Exhaust, etc, etc. Im not so much looking for more power, just maybe a extra mile or two per gallon.

I have said before I am getting almost 2 mpg better since putting in the Volant Intake. More air in the mix turned into better hp and fuel efficiency. I'd say that thing will pay for itself easy in a year.
