The 6 separate ignition coil-on-plugs:

- change low voltage signals from the PCM to high voltage pulses.

- deliver the high voltage pulses to the spark plugs.

- are connected directly to the spark plug.

- have replaceable ignition coil-on-plug seals.

The 6 spark plugs:

- change high voltage pulses into a spark which ignites the fuel and air mixture.

- originally equipped on the vehicle have a platinum-enhanced fine wire electrode for long life.
