Which spark plugs do you guys recommend for the above engine, it is for my 1993 K2500 suburban with the 454.

OEMs are AC CR43TS and gapped at .035(unless the label on the core support says otherwise).

Thanks, I should have noted that I knew what the stock ones were. I was just wondering if there is anything better that people are running in these same engines that works good for them.

I thought of going to platinum‘s, but wanted to make sure they didn’t cause any other issues. I don’t mind paying a couple extra bucks for plugs if they provide an improvement with no downside.

I’m wondering the same thing! Should I get double platinum or? I’m not sure what the bbc like

You only need single platinum's for a distributor. Double is for waste spark systems.
