Well winter has come, and that means I get to spend money I don't have on new things for the GT. Besides me throwing on a new two-tone paint job, I'm looking for the little things as well. So, what are the best plugs, and what difference do they make, if any?
Autolite Coppers for N/A and NGK TR6 for anything with a power adder.

to tell you the truth i had the plugs from ford and thats what was causing my car to missfire in a couple cylinders... i changed them to a colder autolite douple platnum and they are amazing. i heard alot about ngks as well but im running autolites PP 103's and they are absolutely amazing
Almost all are fine to use. some depends on your setup. Get copper if you want performance, platinum for longevity. Best are usually some of the autolites and NGK stuff. Ford stockers aren't bad if your stock. I always use NGK with no problems at all.
