NCT helped Champion to make longer lasting spark plugs. The product development involved detailed investigation of the effects of design and shape of the electrodes. This has been achieved by optical metallography and Scanning Electron Microscopy. Champion aims to make a spark plug which will outlast the car it is fitted into. This ambition is a battle against the changing engine environment.
Engines run faster and at higher temperatures, and with unleaded fuel.
Champion has achieved success in the USA, with a 100,000 mile plug. This is because of their less aggressive driving style and lower speed limits.
