PS.
I douby you will improve your MPG's by adding an intake.
If anything you will decrease your MPG's but not by much because you don't gain much power with an intake.
The more air that goes into the intake manifold, the ECU must compensate by adding more fuel for propure mixture.
More fuel being consumed equals a lower MPG
But cooler air burns better, so I think it kinda balances the ECU out. I don't think you really lost mpg, but if you do I'd assume it's very miniscule. The big reason I lost mpg is because I love to hear the engine rev now, so I punch it way more often.
I was in Jersey City (NJ) last night and it's down to $3.40/Gal.
