Maybe I can get a response on this thread. I have MSD 8.5 Super conductor wires. What is the best type of plugs for my GT?

 

wish I could help but I'd be telling a lie if I said I knew

 

anything that is platnum or better. i use autolite platnums. dont use bosche, they dont last. the iridium (dont think thats how its spelled) plugs will perform as good as platnum, but will last longer. only problem is they cost more too.

 

Thank you. At least there are people that will speak up. I have heard to use Autolites and I am going to try them, thank you luckythirteen13.

 

I have a buddy who works for the Ford company here, he drives a 5.0 and there is not a car in town who can touch his, he uses benzo iridiums and I wouldn't argue with him cuz he is running a low 7 in a 1/4 mile on the track
