The Denso Iridium Power IK24 spark plug is engineered for performance and durability. Thanks to its ultra-fine 0.4 mm iridium electrode tip, it ensures precise ignition under extreme conditions. Iridium's high melting point (2446°C) and high conductivity make it the ideal material for sustained combustion and efficiency.
Denso's patented laser-welding process guarantees a perfectly centered electrode, enhancing spark stability and lifespan.
