Are these the correct plugs, they have half as many threads on them as the ones I am taking out.

Yes, these are the standard Autolite replacements. I just put some in my 93 SC. They work fine. What are you taking out?

I just wanted to double check before I did all that work. I took out Bosch single plats. I didn't pay any attention to the number. The shape and length was the same but the Bosch was treaded about twice as much as the Autolites. Who knows what previous owners have done.

You have to get those single plats out. These DIS systems require double plats because each plug is fired twice each cycle, on compression and on exhaust. The current flows in different directions for these two firings so BOTH electrodes will get eaten unless they are both platinum or iridium.

I've only had the car for about a year and just realized the other day what plugs were in there. I had already heard that we should have double plats. So that is why I changed them. Not a very fun job but I'm glad it's done. Thanks to everyone for there help.
