The autoparts stores will not help you out. They just want to sell you the stock plug and don't understand why you want different ones. The same thing with belts, when we go in there to get a belt, we give them the number and they are just like, what car is it for. Then you say it isn't in your computer i need this number belt. They say, Every car is in our computer, what is the car. So then I just play along and say it is a 2002 GTP, give me the belt, and then I want you to go out there and fit it on my car. Then when they figure out it doesn't fit, I say, dude, I have an Intercooler, I need a longer belt because there is a longer reach, give me this number. Then they are all pissed because they are wrong, and then they get the right belt, but this is 20 minutes later. Anyways, Stock plugs but 1 range cooler are AC-Delco 41-932 (I think it got changed now but thats what it was 3 months ago), and 2 ranges cooler are 41-919. They need to be gapped at about .58. We have 41-932'* in our 2000 SSEi and they are gapped at .58, and we have 41-919'* in the 2002 GTP gapped also at .58. I don't know the number for the Iridium ones, but I am sure they are available. Go into the store, give them the number 41-932 and tell them it is an AC-Delco plug, and they should be able to get it for you, unless they are stupid like the people at my autoparts store.
