WD45 Looking for a hotter plug for the motor. what is the longest reach I can use and brand type?

You want a hotter heat range not longer reach. BTW, I bought a 53 WD from the original owner when I was a kid, and they told me to only use AC plugs,they were right. The Champions lasted about two weeks.

AC Delco 46 or R46 or hotter yet 47 or R47.

My self I no longer use the auto lite plug because they do not hold up as well as they once did. I now use NGK plugs in my tractors and I have a set of NGK3112 in my WD45
