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. If you are unsure of which spark plug you need, please feel free to email us quoting your bike's make, model, cc and year, and we will be happy to advise. Spark Plugs are supplied in singles unless otherwise stated, picture used is for illustrative purposes, meaning spark plug pictured will vary in shape/size to the one received. NGK Iridium offers extreme ignitability, improved throttle response and superior anti fouling Iridium has an extremely high melting point & offers greater protection from chemical attack Allows the use of an extremely small diameter electrode (0.6mm) without compromising the spark plugs service life Combined with the use of the taper cut ground electrode this spark plug has superior gas flow properties & lower voltage requirements
