Intake Manifold
and
Intercooler
I took a manifold from a stratus, I believe. I saw off most of the runners for welding a 5" OD tube too.  I purchased this tube from Ebay. It is 5.0 OD x 18" x .120 wall.

First I cut the tube length wise so I could get inside and smooth out the ports.
Then, I welded the other piece back onto the intake
The notch in the inake is for movement of the engine near the radiator inlet.  I didn't want to take any chances.
I welded 3 stock T2 intercoolers together
