Spark Plug: Description and Operation
OPERATION
The spark plugs change high voltage pulses into spark at the gap which ignites the fuel and air mixture.
CONSTRUCTION
The spark plugs have a platinum enhanced active electrode for long life. The active electrode is different for LH and RH sides.
Replacement plugs have both electrodes platinum enhanced so they can be used on either side.
