Designed for circuit performance. Iridium Racing plugs maximize machine performance to contribute to victory.

Achieve high power with an ideal combustion cycle. Superior ignition performance and spark voltage eliminate misfires and ignition errors across various operating ranges. This significantly improves combustion conditions and increases engine output.

Overwhelming acceleration performance cultivated on the circuit. Iridium Racing plugs feature a 0.4mm diameter center electrode, achieving unprecedented ignition performance and spark voltage. This suppresses misfires and realizes stable high response and improved acceleration even under harsh conditions.

0.4mm diameter iridium alloy center electrode. The thicker the center electrode, the greater the cooling effect, which degrades ignitability. In contrast, the 0.4mm diameter iridium alloy center electrode has minimal cooling effect and retains heat, reducing misfires and ensuring reliable ignition.

Reliable durability. Features a unique all-platinum ground electrode designed to withstand intense racing conditions. Compared to the nickel alloy used in conventional spark plugs, platinum has a higher melting point, reducing electrode melting and wear. Additionally, the 0.8mm square platinum alloy is welded to form the gap without bending, eliminating residual stress and improving durability.
