but i have 1 question i want answered befor i do the swap.
mine now is a stock ls1 intake being a 99 an all and im switching to the fast lsx intake, do i still need the coolant passage package like TSP sells ect?

I got mine from the delearship and paid almost 50 bucks for them. I know that SLP sells a kit as well...I am sure its also around 50 bucks.

Be careful of the rear sensor. Just need the GM cooling lines. You also need to think about what you are going to do about your EGR.
