Tommy,
Actually a "Turbine Only" glowplug is made Aldon Kelly, aka Merlin Glow Plugs, Inc. in the USA. This plug has an extended nose to position the element deep within the combustion chamber of model turbines. It is available with either platinum or nichrome elements. They were sold some time back by Carlos V. and DreamWorks. I've had best success with the nichrome element in my FTE and RAM turbines and having Al produce some more for me.
Rgds,
