I am running the AC-Delco 41-932'* which are 1 heat range colder. Didn't notice any major performance but it needed plugs so I went by one of the guys recommendations on ClubGP.

I got the NGK Iridium IX from GrandPrixStore.com for my 3800 Series 1 SC and they are working great.

Guys I'm gonna have to be the bad apple here. I don't like NGK sparkplugs...

I've had bad experience with them. Overheating and bad performance. Also the price just seemed a little cheap for a "performance" plug. But it could just be a bad run of the mill. I will strongly agree that Bosch plugs are plugs from hell. I've had friends go through those things like beer at a frat.

Currently I use Splitfire, very nice and great improvement over NGK in my opinion. Now I'm not advising you to not go out and buy NGK plugs, only way to find out is to go out and buy different plugs and try 'em out if you got money and time to burn.

Default DON'T FORGET THE WIRES

SAY DON'T OVER LOOK THE WIRES.. The new Platinum plugs last A along time but the wires are very easily broken inside. They get brittle with heat and start to break down. I think they should always be changed with the plugs. Just an old timers opinion.

AC Delco Platinums ARE NGK Irridiums anyways! NGK got the AC Delco contract back in 97 for the Vortec Engine. Now All AC Delco plugs are made by NGK, hence the P/N change over in the last little while!

Not the Rapid Fires, just the AC Delco Platinums ARE NGK Irridiums! And they go anywhere from $13.00 CDN to $20.00 CDN per plug!

I got the NGK Iridiums in my '95. They ran me around $40US and they have been doing very good so far, no complaints.
