| With Iridium Alloy Center Electrode Employing a high melting point iridium alloy tip for the center electrode tip, a fine dia. of 0.4mm has been realized. This fine electrode has led to a lower spark voltage and a large increase in ignitability, which draws out even more output and accelerator response from the engine. (Melting Point: Iridium 2454°C, Platinum 1769°C). |  |
