screamin demon coil spark plugs?
I just got screamin demon coil in the mail today. The instructions say that to gap the spark plugs .065. About 8,000 miles ago I changed my spark plugs to denso iridium spark plugs. My question is should I just regap the iridium plugs or sould I just go to the auto store and buy some motorcraft plugs?

iridiums are good plugs. I love the small tapered end. I'm not keen on changing plugs for the sake of changing plugs. This reality came to me when I swapped plugs and stripped the threads. What a pain.
Because of that experience I'd rather get a get set of double plat or iridiums and forget about them for 50,000 miles. Maybe run like you have now and if you don't see a mpg improvement, pull and regap them.
