I have an '03 5AT coupe and ordered the ATI Procharger. It should be here soon (hopefully). Anywho, i was wandering, which set-up is best suited for my car once the chrager is there: An intake manifold or a Spacer? Which is best for preformance and sound? I also have the HKS hi-power exhaust with an injen CAI, and cat-less pipes. I've researched the whole forum on this topic, but have yet to see a thread with the same or atleast somewhat same set-up as mine. Also, whichever u guys think is best, which brand would be the best as well? THanks a lot guys, I can always count on this forum to give me sound advice. Thanks again in advance everyone.

 

anyone??

 

crawford plenum or motordyne 5/16 isothermal spacer. up to you if you want a new plenum or want to keep the stock.

 

Kinetix SSV is good for FI.. but it has like a $800 price tag... but also looks very slick
