NGK SPARK PLUG CR9EKB 2305

NGK Dual Electrode Spark Plug - CR9EKB

Overview:

• NGK's superior heat range is achieved through the use of copper wire, replacing conventional iron cores. This enhances heat dissipation, cooling the electrode and insulator tip more efficiently.


• The spark plug features a higher pre-ignition rating, owing to its high conductivity copper and elongated nose insulator, making it suitable for high-performance engines.

Additional Information:

• NGK CR9EKB spark plug is designed specifically for motocross applications like KTM SX-F250 (2006-2011).


• Features a multi-ground plug design with a 10mm thread size, 19mm (3/4") reach, 5/8" (16mm) hex size, and a gasket seat.


• Includes a resistor, projected tip, solid terminal nut, dual ground electrodes, and a .031" (0.8mm) gap.


• The multi-ground electrodes improve ignition capabilities and are less sensitive to voltage requirements due to gap growth.


• Designed for various firing tip self-cleaning abilities, including supplementary gap, intermittent discharge, or semi-surface discharge.


• Maintains all features of traditional NGK plugs, including corrugated ribs and pure alumina silicate ceramic insulator, ensuring greater strength and better heat transfer.


• Copper-cored and triple-sealed for enhanced heat removal and interior leakage prevention.

Part Number:

• 37-CR9EKB (Source: oro2u.com)

Note:

• NGK's traditional plugs are designed for longevity and optimal performance, with corrugated ribs to prevent flashover and a pure alumina silicate ceramic insulator for superior strength and heat transfer.
