not a spark plug......
  They are primarily used in CHT applications and the most common are 
approximately 1 inch long
and look somewhat like a miniature spark plug (Delco AC and Rochester 
P/Ns 1514340, 1513431, 333A, and 333B). They have a single wire,which 
provides ground potential to the indicator. Other types are 
quarter-turn bayonet styles with two wires (AN5546-1). Two wire types 
rely on resistance changing voltage to the meter. Single and dual 
wire types can easily be checked by comparing resistance from probe 
terminal to probe body or between terminal connectors at a given 
temperature. No informa-tion is currently available in Chapter VI, 
TABLES for resistance values of thermistors.
