Spark Plug MotoDX Plug Threaded Type

【NGK CR9EDX-S 91579 Spark Plug MotoDX Plug, Thread Type, Maintenance, Repair Parts】
・Features a new D-Shape outer electrode material and a ruthenium-infused center electrode! Delivers astonishing, exhilarating acceleration!
・As a spark plug specifically for two-wheeled vehicles, it enhances various performance aspects required of spark plugs (acceleration, durability, fouling resistance, fuel efficiency, starting performance, etc.).
・The D-shaped outer electrode (D-Shape outer electrode) and ruthenium-infused center electrode achieve outstanding combustion efficiency.
・The electrode shape hardly obstructs the flow of the air-fuel mixture! It efficiently guides the air-fuel mixture to the spark gap.
・The electrode shape hardly obstructs the spread of the flame! Achieves ideal, more spherical combustion!
Features
・Excellent ignitability with the D-Shape outer electrode! Achieves smooth flame propagation!
・Achieves ideal flame propagation. Compared to standard plugs and Iridium IX, starting performance is further improved.
・Excellent acceleration response. Outstanding ignition performance improves throttle response during acceleration. It maximizes engine performance from low to high RPMs without stress, achieving excellent ignitability.
・Improved fuel efficiency through enhanced combustion efficiency. Even when idling at traffic lights or in congestion, MotoDX plugs are effective. In idle fuel consumption tests, gasoline consumption is 2.3% less compared to standard plugs.
・Increased thermo-clearance. A new structure resistant to fouling and flooding! The thermo-clearance at the tip of the insulator is increased. This prevents spark leakage and consistently maintains excellent ignitability.
・Achieves long life. Durability is improved thanks to the D-Shape outer electrode made of a new material and the ruthenium-infused center electrode.
