Perfect plug

What can you say more about the TR 6 plug? If you have nitrous or forced induction this is the “gold” standard of plugs.
Even runs great off the nitrous. Just a great plug.

Great for 5.3 GM

Worked great! I used these for my mildly modified 5.3 Chevrolet I went 1 heat range colder and completely eliminated my high rpm knocking.
