Spark Plugs - From 99MY

The spark plugs are platinum tipped on both centre and earth electrodes to provide a long maintenance free life and exceptional cold starting performance.


CAUTION: Do not clean the spark plugs or attempt to reset the spark plug gap.


CAUTION: If the wrong specification spark plugs are used, the misfire detection system is likely to malfunction and corresponding error codes will be stored in the ECM diagnostic memory. Only use the recommended spark plugs.

In the event of a spark plug failure, a misfire on a specific cylinder may be observed.

A spark plug failure may occur for the following reasons:
- Connector or wiring fault
- Faulty plug (e.g. wrong gap, damaged electrodes etc..
- Incorrect spark plugs fitted
- Breakdown of high tension lead causing tracking to chassis earth
