NGK Spark Plug   The secret of the new Iridium IX spark plug lies in the laser-welded electrode made of iridium. With its "minimal" diameter of just 0.6 mm, it concentrates the ignition voltage.     Advantages:   The optimal ignition properties of the Iridium IX spark plugs prevent fouling during stop-and-go traffic.   Misfires or ignition dropouts are prevented. This reduces emissions and protects (if present) the catalytic converter and the environment.   The Iridium IX spark plugs ensure a "smooth" engine run, enhance the riding experience through better acceleration, and thus provide more driving pleasure.   The Iridium IX spark plug lasts at least twice as long as any standard spark plug. Frequent spark plug changes are thus "out." This, in turn, reduces costs.   Highest ignition reliability, even combustion, optimal engine performance, and 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 a "smooth" operation.

NGK Spark Plug   NGK is the world's leading manufacturer of spark plugs.   State-of-the-art production facilities, significant investments in research and development, as well as strong commitment to motorsports, from Formula 1 to motorcycle racing, make the NGK spark plug so successful.
