Depending on the price, always go with AC Delco Platinums in that year of truck.

Heck, I think they have AC Delco Platinum rapidfires now.

Platinum: 41-932 Gap 0.054

Only plugs you should use in your 4.3L.

Thanks Guys. I do have a 99 SLT. I have noticed before that putting Bosch or any other but AC delco doesn't work as well.

Nope, the Ac Delco are made for the truck and perfect very very well.

Plus they are usually cheaper in some cases.

The Spec sticker on my 99 jimmy inside the hood says to gap the plugs at .060. I assume the 41-932 is OEM.

i'm pretty sure all platinum plugs are pre-gaped, and i think i read somewhere to never re-gap them. good luck, i put in bosch plastinum +2's on a 2001 4.3 jimmy and a month later after paying too much, i found this forum and find out what i suspected all along, they suck!!!

quick note, i clicked on the ebay link for rapid fire and ebay says it's closed for that item number.

That's because it was posted a year ago.
