Re: 1954 359 L8 / Iridium spark plug in place of Autolite copper resistor 308 spark plug

Thank you Owen and Howard for your quick replies. I have always valued both of your opinions.

I was taking a shot and intrigued by a hotter plug burning off deposits better and the iridium plugs feature of a fine wire electrode designed to conduct electrical energy better and increase firing efficiency. With iridium being 6x harder and 8x stronger than platinum with a 700 degree higher melting point I surmise iridium lasts pretty long.

We all agree to stick with a 3/8" reach.
God Bless BigKev and thank you !
