first off what year is ur car?...and ya the brand name doesn't matter TOO much it all does the basic same thing...i woulda gone with a AEM CAI......maybe some Nology hot wires...cams and pullies kit..things like that....make sure with the exhaust u get a FULL exhaust...widen the piping..don't just put a muffler on..that will give u nothing...every else i would recommend would be turbo and NOS but i think thats a bit too much..
