NGK CR9EB Nickel Spark Plug (Box of 4) - One Step Colder than OEM - KTM / Husqvarna / Gas Gas 50cc / 65cc / 85cc

Maintain peak power and reliable starting for your mini-moto engine with the NGK Nickel Spark Plug CR9EB, available at RB MX Parts. The CR9EB runs one heat range colder than the OEM CR8EB, making it the preferred choice for riders who have modified their engine, are running hotter conditions, or simply want added protection against pre-ignition and plug fouling under hard racing use. NGK's proven nickel-alloy technology delivers consistent spark under extreme heat, keeping your 50cc, 65cc, or 85cc engine pulling hard from the gate to the checkered flag.

The CR9EB features a solid copper core for superior heat dissipation and a trivalent metal plating that resists corrosion and seizing in the cylinder head. Buying the Box of 4 provides the best value and ensures you have spares in your toolbox for quick trackside swaps.

Key Performance Features & Benefits:

• One Step Colder than OEM CR8EB: Ideal for modified engines, hotter ambient conditions, or riders seeking extra pre-ignition protection over the stock plug.
• Compatible with KTM / Husqvarna / Gas Gas 50cc, 65cc & 85cc: Same thread and reach as the OEM CR8EB — direct drop-in fitment.
• Superior Heat Dissipation: 98% pure copper core allows for faster heat transfer, preventing engine-damaging pre-ignition and electrode melting.
• Corrosion Protection: Trivalent metal plating provides long-lasting anti-seizing properties, making removal easy even after high-heat motos.
• Triple Gasket Seal: Patented sealing process prevents combustion gas leakage, maintaining consistent cylinder compression.
• Alumina Silicate Insulator: High-grade ceramic ensures optimal dielectric strength and thermal shock resistance to prevent flashover.
• Nickel Alloy Tip: Offers a stable spark and reliable service life for high-performance 2-stroke racing applications.

Vehicle Fitment:

• KTM: 50 SX / 50 SX Mini, 65 SX, 85 SX
• Husqvarna: TC 50, TC 65, TC 85
• Gas Gas: MC 50, MC 65, MC 85

Note: The CR9EB is one heat range colder than the OEM CR8EB. It is a performance/tuning upgrade — not the stock replacement plug. If you are looking for the OEM replacement, see the NGK CR8EB. Always verify plug fitment for your specific year and model before ordering.
