I used the AC Delco Plats (I think you have to use them) but I went with Taylor Performance Wires (in red) intead of stock replacement. I am very happy with both. I got both items from Carquest. Paid like $100 for the wires and about $3 each on the plugs but that was with my discount from my job. I am not sure what list is on them. Make sure you read the how to provided in this forum on that one pain in the ass plug to get it out easily.
