Technical Features

The Ultimate High-Performance “M-Series” Spark Plug

The M-Series delivers enhanced ignition performance, exceptional durability, and superior anti-fouling capability.
It maximizes the performance of tuned engines while also providing noticeable benefits for stock engines.

0.6 mm Iridium Alloy Center Electrode

Reduces required voltage for improved ignition efficiency. 
Offers excellent durability even under high-stress conditions. 
Uses a high-quality iridium alloy for long service life.

Platinum Square-Chip Ground Electrode

Greatly improves wear resistance.
Works together with the iridium center electrode for stronger ignition performance.
Shortened tip and tapered shape help increase combustion chamber volume for more efficient ignition.

Short-Type Anti-Vibration Ground Electrode

Shorter electrode length + optimized cross-section increases strength while reducing mass. 
Contributes to improved durability and higher resistance to vibration.

Thermo Edge Technology

Long idling or varied air–fuel conditions can cause carbon buildup, reducing insulation and leading to misfires.
The Thermo Edge at the insulator tip generates micro-discharges, preventing carbon accumulation and maintaining stable insulation at all times.

Auxiliary Spark Gap

Creates additional surface discharge between the insulator and ground electrode.
This suppresses carbon buildup and prevents plug fouling, ensuring stable performance in diverse combustion environments.
