NGK has the technology to produce plugs for every type of automotive engine, as well as for motorcycles, marine, horticultural and many other applications. In fact NGK produces and stocks well in excess of 1,000 different types of plug. NGK always works very closely with the engine manufacturer to ensure a perfect match between plug and machine.
By producing a high intensity electrical discharge within the engines combustion chamber the spark plug provides the heat energy required to start the air/fuel mixture burning. It has to be able to do this many thousand times per minute.
