NGK has been developing spark plug technology since the 1930s and manufacture plugs for every type of automotive engine, as well as for motorcycles, marine, horticultural, plant and many other applications. In fact NGK produces and stocks over 1,000 different types of spark plug and every product matches even the most demanding manufacturers specifications. The vast experience and technology that NGK has ensures that there is no doubt that NGK are the world No.1 spark plug.

• The optimal ignition characteristics of Iridium IX spark plugs prevent sooting in stop and go traffic.
• Misfiring or misfires are prevented. This reduces pollutant emissions and protects the catalytic converter (if present) and the environment.
• The Iridium IX spark plugs ensure "round" engine running, enhance the driving experience through better acceleration and thus offer more driving pleasure.
• The Iridium IX spark plug lasts at least twice as long as any normal spark plug. Frequent spark plug changes are thus "out". This in turn reduces costs.
• Maximum ignition reliability, uniform combustion, optimum engine performance, spontaneous throttle response are the result of state-of-the-art technology and reduce fuel consumption.
• The optimized electrode shape reduces the ignition voltage requirement, protects the engine and ensures "smooth" running.
