Never seen them. What is their application?

Jeep probably.

This "style" spark plug(s) were/are common in the early days/evolution of military vehicles & aircraft (some motor vehicles). During a period of time when some vehicles/aircraft did or did not use a radiator (air cooled) or did not use a thermostat (most did, some did not). There existed good documentation on which heat range spark plug was best suited for the application.

This is a decent read of some applications...

1955 M 38 A 1 jeep. 24 volt electric system with optional Fording system [waterproof ignition ] Takes 2 wrenches to remove spark plugs. Naturally discontinued and hard to find. The "Substitutes " just aren't as good

Norm with Radiator
