You can drill and tap the cover in the same place as std 2wd/4x4 for the ACT sensor. As said before the air takeoffs are at the front and back of the plenum cover.

All of the trumpet sections are the same, 2wd, 4x4, Small turbo all smae so any cover will fit any

Your throttle body holes will need opening up from 6mm to 8mm to clear the bigger bolts the EECIV plenum uses.
