Spark Plug: Description and Operation

The spark plugs:
- change high voltage pulses to spark at a gap which ignites fuel and air mixture.
- have a platinum-enhanced active electrode for long life. The active electrode is different for LH and RH sides.
- used for replacement are AGSF-34EE; the electrodes are platinum-enhanced so they can replace either a RH or LH spark plug.
