I have a feeling your fuel consumption will increase. With a larger bumpstick, heads andexhuast the engine will flow more air thus the computer (assuming its aF/I car)will need to inject more fuel to maintain a proper working air/fuel ratio. If more air goes in and no more fuel you'll be lean. My .02.</P>


But there is asunderlying reason fuel consumption will go up. Once you put those parts on you'll be on the loud pedal a lot more. I know I am! WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAA<IMG src=smileys/smiley4.gif border="0"></P>

no hes right it should go up because of a cleaner engine and new parts. the gas will burn more even and it will burn less.
