AR10IR-OE – SPARK PLUG AR10IR-OE (KTM OEM)

THE SPARK PLUG

The BRISK AR10IR-OE is an OEM-developed Iridium Racing spark plug designed in cooperation with KTM, GASGAS and Husqvarna factory racing teams for modern 50cc and 65cc SX, MC and TC models (2024 onwards).

Developed through joint testing and race-level validation, this plug was engineered to guarantee reliable ignition across the entire power range of high-revving mini motocross engines. With performance-focused updates in modern race bikes, the AR10IR-OE ensures consistent combustion, improved throttle response, and enhanced reliability under extreme conditions.

IRIDIUM RACING TECHNOLOGY

Iridium is up to 6–8 times stronger than platinum and has a melting point approximately 1200°C higher, making it exceptionally durable under high-pressure, high-output race conditions.

The BRISK Racing Iridium “Power Focus” design positions the spark precisely in the focal point of the reflector, directing the air/fuel mixture during compression toward the centre electrode. After ignition, the flame front propagates more efficiently toward the centre of the combustion chamber, improving combustion efficiency.

The optimised 1mm iridium centre electrode combined with a cut-back ground electrode:

• Requires lower supplied ignition voltage
• Improves spark stability under load
• Reduces quenching
• Allows better air/fuel mixture access
• Supports ignition of lean or difficult fuel mixtures

This design is particularly beneficial when stock ignition systems are pushed to their limits in race or modified applications, and it also improves cold starting and resistance to fouling.
