4.9 plugs
« on: September 29, 2019, 04:26:11 pm »
Anyone have any recommendations on 4.9 plugs? The 4.9 Formula has AC Delco 41-902 in it that need to be replaced. I think that is part of the motors laziness. Any other suggestions?

What were the stock plugs for the 4.9?

Which PCM are you using?

Are you asking for brand recommendations or a specific plug part number? You can't beat AC Delco in a stock application. Champions Maybe?

I asked my brother Mike. He said he has had his 4.9 Fiero for 3 years, and has never changed the plugs yet. So he doesn't know what they are.
