Gm uses a different coil for l67s..the icm is the same..thr l36 coil pack will still work not sure what the difference in coils is if any but they are different part numbers for some reason.

No there isn't a difference. They are exactly the same. There have been different part numbers due to gm sourcing parts over the years but functionally they are identical. Some people say there is a voltage difference and whatnot but in reality our icm controls how hot the spark is so a coil isnt going to do much if anything.Originally Posted by timboku

There indeed is a difference according to GM. The L67 coil is supposed to have a stronger spark and perform better under a load. Those factory L67 coils being identifiable by the dark blue plastic around the contacts on the bottom side of the coil.
