I have been cleaning up old stocks here... and we have a large surplus of slightly used inlet preheaters (heater plugs) that are presently just going to waste. These are 12 volt military take-offs that are basically unused although maybe blemished and dirty from original installation. These are the heavy-duty versions. We have already discarded anything that had any signs of wear and tear so they are guaranteed good. These could be used for your projects with just about any type of engine that needed a little cold-weather starting assist. All you need is a 12 volt battery and a little simple wiring to make these work.
Lister has them priced at $100 a copy... I will give them away for a simple handling fee of $10 plus post. Large quantity available.
