What is the correct autolite spark plug number, or is there a few different to choose from working on a 3/52
most correct for restoration
drive-able correct
you get the Q
thanks steve

Auto-Lite 2243 for the colder plug which was the original for the M38 and Auto-Lite 2245 for the hotter plug which was the original for the M38A1.

Would running 2245's in a L143 that is bored to 80 thousands be bad for the engine over time?

I don't see how it would unless one is running radical fuels or compressions.

Here is a link to the autolite 2243 plugs on Amazon.
