I was at the dealer today, they quoted me 285 bucks CAD....and apparently there is no core return on that. So besides the expensive ones from the dealer what else do u recomend, can i use one from a bonneville that is N/A even tho mine is */C??? Any cheaper brands that will work as good?

Borg Warner is the only other brand I would trust besides AC Delco, You can get them at Federated Auto Parts stores.

if i lived in the United States. lol

Then just go AC Delco.
