If the factory plugs were iridium, I recommend spending the extra money to replace them with iridium plugs. They last longer than copper (100,000 miles usually) and (just my unsubstantiated opinion, take it with a grain of salt) I believe you will get slightly better fuel mileage out of the iridium compared to copper.
We can't run them in our Boosted cars, but in my NA Bonneville I always preferred to put in the iridium plugs and forget about them for 100,000 miles.

I went with the Autolite double platinum plugs and it only took about 2 hours with help from a neighbor to help with the EGR valve (sucked) and the 2 studs that hold the beauty cover on the rear.......so i see it that is saved myself $250 bucks.

I'm surprised no one chimed in on which plugs to use, or that Autolites were recommended... There have been other threads on this topic either here or bonnevilleclub forums. Seems to me the AC Delco Professional Platinum plugs (Part Number: ACF-41-987) work best and have 100,000 mile intervals. Northstars came with these plugs from the factory.
