*You can use the C&L maf, the rest I don't think so. The bullit intake is really only good for Supercharged applications, otherwise its only good for like 5hp N/A. Not hardly worth the 1600+ investment, it might get you more if you have it ported, but still not worth it. There are at least two aftermarket intakes out now that are less money and a lot more gain.

yeah if you are going to spend that kind of money on a new intake, and want upper and lower, i would go with a P-51 from Fox Lake racing. Now if you want something more bang for the buck...hit up a C&L Plenum, 75mm Accufab TB, and for some good looks get a C&L Tru flow inlet pipe, if you don't really care about the looks, then get a K&N intake kit off ebay
