I just purchased some c o p for my 06 GT. They are MSD blaster coils. New here... can anyone recommend a good spark plugs for these coils,should I run a colder plug with a larger gap?

 

You should not run a colder plug unless you have a blower. I would not increase the gap either. I've had good luck so far with the msd's on my car. I have my gap set at .032 per whipples instructions, but may try a bigger gap next time.

 

If you are stock stay with the stock heat range. Most people around here like the Autolite HT's. I've run mine for 15,000 with zero problems.
