hey guys, I am thinking about eventually getting an intercooler because my GT1 cam works best with intercooled boost..and I am top swapping my car this week. I just have a couple of question for you all..

1) can you just get the core like this one? ZZ Performance or do you need all the piping etcm like this? TRANS AM GRAND PRIX 32" INTERCOOLER+2.5" PIPING KIT on eBay!

2) are they easy to install? I just want a cheap way of doing this..something simple.

3) what about this one? 32x12x4 FRONT INTERCOOLER PONTIAC GRAND PRIX FIREBIRD on eBay!

I guess I just don't understand the concept of intercooling, do you need the whole front part, all the piping, and the part that goes under the supercharger? or can you just do one and it will be good and efficient?

thanks!
