The Drag Specialties M8/XG E18-6724DS Spark Plug is designed for compatible Harley-Davidson Milwaukee-Eight and XG engine applications. This replacement spark plug combines reliable ignition performance with durable construction for motorcycle riders who expect consistent starting, responsive throttle operation, and dependable service life. The black ceramic body and bold red Drag Specialties logo provide a distinctive appearance while maintaining the quality needed for demanding engine environments.
Fitment: Designed for select Milwaukee-Eight and XG engine applications; verify vehicle fitment and the original equipment spark plug specification before installation. The E18-6724DS manufacturer and vendor part number identifies this Drag Specialties replacement component.
Construction: The insulator uses 95% pure alumina for strong resistance to heat shock and effective electrical insulation. Its multi-rib design helps reduce the risk of flashover, while the nickel-plated housing resists oxidation and corrosion. Multi-layer gaskets and a heat-crimping process create a leak-resistant, gas-tight seal for reliable operation.
Performance: A copper-core electrode supports efficient electrical and heat conductivity while helping resist oxidation and corrosion. Together, these features promote dependable spark delivery and extended spark plug service life in compatible motorcycle engines. Install according to the vehicle manufacturer's specifications and use the recommended tightening procedure.
