Hi looking for a back up replacement over here in Aust, are the cheaper versions worth buying or are the AC delcos the only way to go (and pay a heap more)?
Thanks Dick
Our Duramax engines seem to do better with genuine GM parts. However, I understand that the aftermarket is much cheaper. I'd try an aftermarket and see if it worked, ONLY if I also understood I still might have to buy the GM OEM part, if the aftermarket fails.
