difference between tr55 and tr6 plugs?
difference between tr55 and tr6 plugs? like the title says, whats the difference between the two spark plugs? i've seen the msd plug wires with the ngk plugs and seens these two plugs are priced the same..
TR6 is one heat range colder. Better for FI or Nitrous applications to avoid detonation. I have also heard that you should go to a colder plug when you add 50rwhp, but not sure I believe that. I'm ~150rwhp over stock and still running the TR55's w/ ~11.1:1 compression.
