Has anyone checked to see the type / name / part number of the spark plugs installed ? :confused:

For the 2.2 or 2.4? The GM and ACDelco part numbers are in the manual.

For the 2.2 - GM# 25337472 ACDelco# 41-981
For the 2.4 - GM# 12599232 ACDelco# 41-981

Both numbers are good.. seems the same.. Just wanted to know if there was a difference between the 2.2 and 2.4

Yeah, it seems kind of weird that the GM numbers are different but the ACDelco are the same. :confused:

GM part numbers are crazy, I would almost be positive they are the same plug.
