The NGK spark plug wire set for Checker Marathon (1978–1979) supplies reliable direct-fit ignition wiring with ultra-low-resistance mag-core construction. Stainless steel winding over a ferrite core minimizes electrical loss and suppresses EMI/RFI, while high-temp silicone jackets and EPDM/silicone insulation enhance dielectric strength. Spark plug boots are glued and sealed for watertight connections. Supplied as a 6-wire set (coil lead not routed) and backed by a limited lifetime warranty.
