What is spark plug fouling?
A It is a phenomenon by which carbon accumulated at the firing end causes electrical leakage that leads to misfiring.

What kinds of spark plugs offer good resistance to carbon build-up?
A A spark plug designed for the spark to jump along the insulator surface of firing end, in order to burn off accumulated carbon deposits which may lead to fouling. The intermittent discharge plug, the spark plug with a supplementary gap, and the semi surface gap type.

What is the Iridium spark plug?
A Iridium has very high melting point at 2545 centigrade much higher than that of platinum at 1772. This allows the electrode to be thinner than the platinum type, improving ignitability. In addition, the thermo edge designed in the Iridium spark plug makes it highly resistant to carbon fouling.

Why is the firing end appearance of a spark plug important?
A Because the firing end appearance reflects the suitability of the spark plug as well as the condition of the engine.
