are the ngk tr55s a step colder? and which ones are guys going with just the V powers or what? it doest say anything about them being a step colder...
I beleive the TR6 plugs are the ones you want. Hope you dont plan on running them in the winter:help: . I will say one thing One step colder plugs +42lb injectors+ cold weather= car not wanting to idle lol.

I use TR6's and have a 8.8:1 CR running #42 injectors & 80mm MAF ... car idled just fine yesterday when I started it in 20 degree weather.
To simply answer your question, TR55 plugs are STOCK heat range. Not sure why you did not get a straight answer the first time.
Touchy touchy... go play with a dildo or somethin and chill.
Wow. You got to be kidding. Just so you know, what you said says more about you than me. Time for you to grow up? Perhaps.
i had TR-7 plugs in my car for the 100 shot. dealers told me that the plug didnt exsist, but at the time i worked for a snowmobile racer that was sponsored by NGK so i contacted their sponsorship guy and he sent me out two sets. they exsist and the car ran great with them. however, i have an aftermarket ignition which might have made the plugs perform just well enough in the winter. i wouldnt suggest it for any normal driving or small nitrous shots.
the TR55's are in my 3L now. they seem just fine
(for future reference, most company's use a lower number heat range as a colder plug. NGK doesnt do this because stupid people buy hotter plugs thinking they will enhance performance but only make the engine detonate)
