Hello all, so i don't need my rear 02 sensor anymore, and was just wondering if the size is in fact 18 x 1.5, and if an oil pan plug of that size would work, or if the threads are different.... Thanks.

Yes, it is M18x1.5 (18mm wide, 1.5 pitch), but no the oil drain plug won't work, it's M12x1.75 so not even close. You can get a plug on ebay or amazon for 3 bucks plus shipping or just go to a hardware store and get a M18X1.5 bolt (I like the shoulder bolts) and cut it down if you have to. That's what I did and it's working out great so far.

Oh sry, i forgot to mention I found an oil drain plug that was off something else, not the grand prix. It was only 3 bucks at Canadian Tire and M18 x 1.5 so i got it just in case i couldn't find an actual bung plug... Thanks for your quick reply!
