Hows it goin? Welcome to CEG...
1. Ebay intake = waste of money....search and you'll find that the K&N RU-3530 with the MAF adapter is the best way to go
2. Ebay chip...They're worthless, the performance they give you is like sayin the hail dents on a hood are speed dimples...Firstly, you dont want to do a chip till the very end, and when you do...do it right or dont do it at all...search for ADC chips or other custom tuning packages
3. Check out the duratec performance thread and check out the stickies at the top. You could also check out the 3.0 thread and those two will be your best bet and trust me it'll keep you and your wallet occupied for quite some time...
Heres the link to the duratec bolt-ons...
