Gotcha.

Backwards.

NGK OEM'* Delco, but Delco doesn't carry the V-power design.

I run the iridiums, they are supposed to last longer by using harder (precious) metal, sort of like the platinum plugs but better (I dont think platinum does well in the 3800, especially bosch). Your biggest concern is going to be the heat range of the plug, if your doing slight mods you want 1 heat range cooler, moderate mods 2 ranges, and heavy mods up to 3 ranges. This will help reduce your KR and keep you running max power. I recommend NGK but AC Delco will do fine if your on a budget.

I've heard good things about the Denso'*, but I don't know how that little electrode would hold up in a SC engine. Someone needs to try these. Should I take one for the team?
