Ngk tr 55 plugs ???
So I was tinkering with the z and I see tr 55 plugs showing a gap of .60, from what ive seen these aren't the correct replacements. Why do you guys think this is? Did my car have nitrous? turbo? supercharger? at one time? Cant figure this one out, especially because of the gap, I thought youre supposed to have a smaller gap for forced induction so the spark doesn't get blown out.... interested to hear your thoughts....

TR55 is just a stock replacement plug with standard (non-platinum) electrode.
