That pipe has the o2 bung in it. I had one done and finished coating it all in the same day and finished about 12 at night. So you have both of the kits
No. You dont beed them. I think they come with the intercoolers. I already sent you what you needed as far as washers and bolts with the water line stuff.
After getting Leo's cams degreed and finished, with just a little time left in the day, we decided to install at least "something" new. So we installed the radiator supports and intercoolers!
The tubular radiator/intercooler support is 7 pounds, compared to stock 17 pounds; nice little savings there. A very nice piece!
We'll get more of the hot-side and other stuff next time.
A couple pics:
intercooler in place, roughly, but not bolted in on passenger side (and spacers not in place, hence it looks tilted):
under-car radiator support with an aftermarket radiator, stock auto trans cooler, a/c condenser, my 'relocated' power steering loop line in the middle, and back-side of the intercooler.
