About this product

Description
The Denso IWF24 Iridium Spark Plug is designed to withstand extreme conditions and provide consistent performance. Its iridium electrode, six times harder than platinum, can endure temperatures up to 4,000°F. The ultra-fine 0.4mm iridium electrode reduces voltage requirements, enhancing firing performance. The 360° laser-welded electrode creates a robust seal, resisting wear in the most demanding environments. The tapered cut and U-groove design of the ground electrode create a large volume area, optimizing flame propagation. This resistor-type spark plug features a 14 mm thread size and a 12.7 mm (1/2") thread reach, ensuring compatibility with a wide range of engines. With a 0.9 mm spark gap and a heat range of 24, the IWF24 spark plug provides excellent ignition efficiency.
