I never put foam underneath my lsx intake and everything seems to be fine. Don't forget to use the valley cover bolts that Fast provides with the intake. Failure to do so can/will result in a cracked intake. I put some RTV around where the map sensor goes in the intake to prevent any leaks.

Yes, there are fittings for the brake booster and other vac line on the back of the LSX intake manifold. Also be real careful that you don't damage the oil sending unit!!!!

The sending unit on a C5 isn't as easily broken as the F-body one.

You should be able to use your stock coolant cross over tube setup. Tube in the front and block off plates in the back two holes.

On your car you should have a "U" shaped PCV/hose assembly that attaches from the Intake behind the TB on the passenger side and then to the valley cover. The LSX intake is wider at the TB area and I had to use a longer 11/32" hose that attaches to the valley cover from the PCV valve to make it fit properly.

It goes into your TB. I have a NW TB that has the provision for it, don't know if the TPIS TB has it though.

I just put a breather on the valve cover port. No problems so far.

Also, I installed the "Home Depot" catch can mod on the valley port. I haven't caught any oil yet.

Glad I could help...

My LS6 intake was wet, too. The catch can mod is so easy, i figured why not?
