Wondering what you guys are running in the Assault 325. Manual says AC 41-932. Not available anymore. Replaced with AC 41-993 a few years back.

Another option for spark plugs on the 325 engines. Stock many came with AC 41-993 Platinums (gapped at .060), but these have been replaced by AC 41-101 Iridium (also gapped at .060)

So, what have you guys been using? Results? Thoughts?
Hey Kane. Running 41-933 in mine for 2 years. No problems. That's what they crossed the 932's over to
I have the 41-993s. Bought a box of 8, but did not put them in last year. Existing ones looked fine.

If your engine dose not have catalytic converter exhaust, I would recommend using conventional AC/Delco MR43LTS plugs gapped at .045.. Any catalyst engines should use platinum or iridium plugs. The plugs we used in the cat 5.7L engines have superseded to 41-101 gapped at .040.
This makes a lot of sense. Think I'm going conventional.Quote:

I just switched my non-cat 320HP Assault over to MR43LTS. Just one day's use so far, but noticed no ill effects. The wallet really likes them.
11 lb. ft. is the magic number per the GM service manual.Quote:
