M37 Spark Plug wire Replacement

[Wayne Hingley]

Does Champion XED14 cross over to anything known?

Not a common plug. Even if it looks similar to an M37 plug I think you’ll find the porcelain insulator comes too high in the barrel: preventing the insertion of the M37 spark cable.

Thanks Brian. I didn't open the package to see what they look like, but have seen other plugs with the features you mention. Do you know the application(s) for these XED14 plugs? A friend has several.
