Scotty,
I'm getting ready to replace a plastic upper plenum on a 1999 Pontiac Bonneville SSE 3800 series 2 with the later aluminum upper plenum from a 2007 Pontiac Bonneville. The torque specifications on the plastic upper plenum is 89 inch lbs. I am wondering if the torque specifications on the newer aluminum upper plenum are different for the older plastic upper plenum.
Thanks for the help.
