Description
The Denso IU31A Iridium Spark Plug is designed for enthusiasts and professionals seeking the ultimate in ignition performance. Featuring an iridium electrode that is six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this plug ensures exceptional durability and reliability. The ultra-fine 0.4mm iridium electrode reduces voltage requirements while dramatically improving firing performance. A 360° laser-welded electrode provides a robust seal, resisting wear even under extreme conditions. The ground electrode incorporates a tapered cut and U-groove, creating a large volume area at the flame's center for enhanced combustion. This resistor-type spark plug with a 10 mm thread size and 19.1 mm (3/4") thread reach guarantees a precise fit and optimal function.
