I'll be interested to see how badly the fuel consuption is affected after the Intake, Pulley and ECU are done. I know we didn't buy these cars for the fuel economy, but that does factor into my decision as far as mods go. I drive 40 miles a day, and if it hits it too bad, then I don't think I'll be able to justify it.
