Spark Plug: Description and Operation

The spark plugs:
^ change high voltage pulses to spark at 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.

Original spark plugs on the RH side (cylinders 1,2 and 3) spark plugs are AGSF-34EG.

Original spark plugs on the LH side (cylinders 4, 5 and 6) are AGSF-34E.

Replacement spark plugs are AGSF-34EE; the electrodes are platinum-enhanced and can replace either a RH or LH spark plug.
