Replaced my knock sensors saturday, was tightening the last intake plenum runner bolt with torque wrench and heard a snap, the ear cracked, think the gasket wasn't seated correctly, I know it sucks, I have a line on 2 used plenums online but wondered if the 91 plenum is the same as my 94. if I can get the cracked ear to tighten the runner down could I fill the crack with some kind of filler?

I believe they're different... Joe would know for sure... I know the runners are different.

from what I found out, they must be different because they list the plenum from 91-2/94 as one part number and than after 2/94 as a different number.

91 to 2/94 $ 636after 2/94 $ 776from everythinginfiniti.com

Interchange manual lists them as the same. You could have my spare from a 1993 for $50 shipped and you could send it back if by some chance it didn't fit.
