About this product
Iriseries plugs are iridium plugs with excellent ignition and acceleration performance for tuning engines that require high heat value.
It employs the technology cultivated in F1 and MotoGP. Compared to general plugs, the flame spread is faster, energy loss (quenching action) is less, and starting and acceleration performance is improved.
It brings out the potential of the engine with its excellent discharging performance and strong and quick combustion.
The ultra-fine iridium alloy center electrode improves the electric field strength and generates a more powerful spark at a lower voltage. Furthermore, since the spark is concentrated at the tip of the center electrode, stable combustion is always obtained, leading to improved fuel economy.
