Denso IWF24 Iridium Spark Plug (Single)

Experience superior performance with the DENSO Iridium Spark Plug from Discount Moto Gear. Features: Six times harder than platinum, iridium withstands temperatures up to 4,000°F. With iridium electrodes that can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves. The precision 360° laser welding of the electrode creates a seal that resists wear, even in the most challenging conditions. The ground electrode features a unique tapered cut and U-groove, forming a large volume area for the flame's center.
