Spark Plug MotoDX Plug Threaded Type

【NGK CR9EHDX-9S 91566 Spark Plug MotoDX Plug, Screw Type, Maintenance, Repair, Parts】
・New D-Shape outer electrode and ruthenium-enhanced center electrode! Achieves an amazing, piercing acceleration!
・As a spark plug exclusively for two-wheelers, it improves various performance aspects required of spark plugs (acceleration, durability, anti-fouling properties, fuel efficiency, starting performance, etc.).
・The D-shaped outer electrode (D-Shape outer electrode) and ruthenium-enhanced center electrode achieve exceptional combustion efficiency.
・Electrode shape that is less likely to obstruct the flow of the air-fuel mixture! Efficiently guides the air-fuel mixture to the spark gap.
・Electrode shape that is less likely to obstruct flame propagation! Achieves ideal combustion closer to a spherical shape!
Features
・Excellent ignitability with D-Shape outer electrode! Achieves smooth flame propagation!
・Achieves ideal flame propagation. Starting performance is improved compared to standard plugs and Iridium IX.
・Responsive acceleration. Exceptional ignition performance improves throttle response during acceleration. It extracts engine performance from low to high RPMs without stress and achieves excellent ignitability.
・Improved fuel efficiency through enhanced combustion efficiency. MotoDX plugs are effective even when idling at traffic lights or in congestion. In idle fuel consumption tests, gasoline consumption is 2.3% lower compared to standard plugs.
・Increased thermo clearance. New structure resistant to carbon buildup and fouling! Expanded thermo clearance at the insulator tip. Prevents spark leakage and consistently maintains excellent ignitability.
・Achieves long life. Durability is improved by the new D-Shape outer electrode and ruthenium-enhanced center electrode.
