Does anyone know if AC delco has a irridium spark plug that will fit the North Star V8? If so I need the part #.

Found the part# its 41-985 for the AC Delco Irridium its not list for our car V8 though but I called them and they said it was the same as the platinum they had listed but in irridium :thumbsup: BTW this is the same plug I use on my LS6 Trans Am motor and the oil filter is also the exact same for the N* as the longer LS1-LS6 motors cool.
