I went through 3 sets of the right type, ac delco 13G plugs that I got from a surplus suplier before I got fed up and switched to the civy controler/ relay. The glow cycle duration will get shorter and shorter over time as plugs start dying off.
I just cut the smaller connectors off and crimped on some 1/4" female spade. Use automotive types they handle the heat better. I ended up converting it to 12v and not looking back "got tired of burning up plugs"
heres my write up on changing it to the civy style controler

I am currently running the same plugs as you with this set up and haven't had any isues.
however if you want to keep the military system talk to someone at steelsoldiers. It could be the resistor "mounted center firewall" it could be the relay "good luck finding one" or it could be the controler card "under the dash by the steering column" some times it needs the connector box cleaned.
