Re: Spark Plugs
I would actually argue that the problem with automotive spark
plugs is the absolutely appaling quenching they would provide. In a small
system they should hold up quite well cooling wise as long as you use a fair
number of them in series and heatsink them. You may be able to get decent
quenching by airblasting them - but standalone the electrode design is very
poor for a tc system. As I'm building a small system for a magazine article
I might give them a go.
