P9. Which is the Green type spark plug and how identify it ?

This spark plug has a 90 V groove at the electrode end to improve ignition capacity.

It is easily identified through the green color of your code and the stamp in the ceramic resistor.

 
 

Characteristics

It has a 90 V groove at the central electrode end.


A V groove guarantees spark production at the electrodes outside border.


The flame nucleus spreads for the extremities of the electrodes, diminishing the loss of energy.

It improves ignition capacity.

• Provides higher efficiency through better start and acceleration, as well as stable idle gear functionning.
• Results in higher fuel saving.
• Reduces the emission of gases not burnt, benefiting the environment.
