okay i got a injen cai, hks exhaust ti, and thats it hahaha....need to make more power...let me know what else should i get??

 

if u have revup get MREV2 and 5/16 iso spacer its awesome !! got mine at streetimage,DRU is the man

 

You should definitely look into a plenum spacer. I have the MD Iso thermal 1/2spacer. Depending on your preference, you can choose between the 5/16 or 1/2. It should match up well with the set up you have. I can tell you how much it helps with the exhaust after I install mine.

 

i have a 2004 g35 coupe....what plenum do you recommend?? does crawford still make some??

 

i got the crawford one homie! you should check it out, if not a plenum get spacers.. or just go my route and super charge that sunn biisshhh
