Hey guys, I just wanted to confirm that I'll be installed the right plugs.
I was looking to pickup a set of plugs a little colder than the TR-6. I was told the TR-7 is the next colder plug. The store was out of these, but the had the Autolite 103's, which they told me was the same heat range as the NGK TR-7.
So, before I install the plugs - can anyone confirm - is the Augolite 103 1 heat range colder than the NGK TR6 ???
