while looking for an oddball spark plug for a customer I found we carry ac delco iridium plugs. i compared them to a regular plug for the J and physically they appear compatible. I did some digging an found out they are for tea Corvette.

1. are the heat ranges acceptable for an N/A motor?
2. would I have any problems with using them with the MSD.
3. anything else you can think of ?

here are some pictures for reference.

I dunno i just got a set for my ecotec, im awaiting the results



1989 Turbo Trans Am #82, 2007 Cobalt SS G85

will the 41-101's be compatbile with the 2.4? Its the same plug used on the 3800 S/C, the Denso (or NGK?) # is the same for both cars too BTW, and if so, what gap for a 98?

Nice. What would a best guess be as far as the gap for an NA 2200?
