Description

The Champion 588 Spark Plug is a military-spec replacement spark plug designed for specialized applications requiring a shielded 5/8-24 ordnance connector and dependable ignition performance. Built with a copper-cored nickel center electrode and standard J-gap ground design, this plug is engineered to provide strong ignitability with a lower voltage requirement than many precious metal plug designs.

Designed for reliable service in demanding environments, the Champion 588 features a gasket seat, non-projected tip, resistor construction, and shielded terminal configuration to support proper fitment and performance in compatible systems. Its durable nickel electrode construction and controlled heat range help maintain stable ignition characteristics in engines requiring military-spec or shielded plug design.

This OE-style replacement plug is a practical choice for applications where shielded terminal compatibility, accurate heat control, and dependable spark performance are essential.
