Spark Plugs D25U pony Engine was created by Al Letts

Hey All,

Trying to procure new spark plugs for getting the pony to run this weekend. I know most had advised me to stay away from Champion Brand. What PN should I look for in Bosch or NKG? I know it's a non standard plug due to the base and thread size. I know there are two PN listed for the D2. I have the early style SN 12614. I know there have been past threads but I can't seem to locate them.

Thanks

The Autolite is a resistor plug and resistor plugs are not recommended. The NGK number is AB-6 and it is non resistor. You can order any of them from this place if you can not find them local.

I have no other connection to these people other than this is where I buy my plugs.
