one piece of advice, watch out for Items on Ebay that says JDM cause most of them are knock-offs.

*Intake: Either AEM, Injen or K&N but with a Bypass Valve
*Exhaust: Greddy if you want it lound or Apexi WS2 if not very loud
*Headers: DC Sports or Greddy
*Spark Plugs: NGK Copper with NGK cables

These are your bolt-ons, I dont know alot about Turbo-chargers and super-chargers so wait for some more replies.
