Originally posted by Juiced46 I run the NGK TR6s gapped at .035. Im about to throw them in the garbage. I got such a horrible hesitation with them its bad. i had nothing but problems with them on my GT as well. I dont know what made me get them for my Cobra. I was going to put the Motorcraft 12c's in, but they do not make them anymore for Cobras. Denos are way to much $ and not worth it in my opinion. I will go with the Autolites and gap them at .030 and see how that works
Yep I agree. I didnt like the TR6's at all. I heard one guy swapped out his tr6 plugs for some Autolite 103's and got 20rwhp! I just bought my 103's yesterday and will install them soon!
