Where do you choose on the IC to drill.
Any place on the "cold side" end-tank where it will fit.
Do you use a standard drill and tap never done aluminum before.
Yes. Just go slower, and back out the tap to clean the threads a little more frequently. No cutting oil needed.
Anyone know the size/ thread pitch of a gm iat.
