Sorry folks i dont have much time to search around on the forum for the info but i was wondering if anyone knows what model if factory plugs (AC Delco ##-#### and once i buy these, do i have to set the gap? If so, what is the gap size?


Thanks for the quick help everyone

No, if you get the correct ones they will be gapped already. Mine were.

41-950
Gap to .050

Thanks a lot folks. I will check the gap just to make sure....

Hmm, mine were gapped to .050 when I got them, and the sticker under the hood says .060. Why the difference?

Interesting. Now....do i go .050 or 60?

We went throught this some time ago. I think the original plugs were .060. When you remove them I believe you may find they are a different number. Gap the new ones to .050

Can you re-gap OEM platium plugs? I was told you can't / shouldn't.

Of coarse you can. They are no different than any other plug except that they have a tiny platinum pad on the electrodes.
