pretty much everything he said^^^ i agree stock thermo is perfectly fine... i actually prefer it. i live in ohio so i know those wonderful winters. if you do headers, go with the ssac and if you do that, you should be fine on a 3.6 thats what im running and i have a dp plog combo knock free. i would try to keep the stock heat range plugs if possible... only drop it down a heat range if your knocking. no need for catback, and yes its true the 04+ blowers do not need or benefit from any porting. i also agree with the cone filter right after the maf. above all, make sure you get a tune. i have a 3800 performance pcm... i love it i think its better than the overkill tune i had.
