Eurocharged tune ($300).. 74 mm throttle body (uprade from the 68mm) and larger MAF housing ($100 +or -)... intake tubing.. Needwings $350 ish to $600ish depending on twin tube or single.. myself I opted for a $65 twin intake "hot air" intake from ebay.

These will "wake" the car up a little... and make it even more fun to drive..
