Description
Overview:
The Champion RDJ7Y is a 14 mm small‐engine spark plug designed for dependable ignition in petrol engines used across construction and garden machinery. Built with a durable ceramic insulator, a corrosion‐resistant plated shell, and a copper‐core centre electrode with nickel alloy electrodes, it delivers a stable spark and manages heat effectively in demanding conditions. The resistor design helps keep electrical interference low, which supports reliable performance with modern ignition systems. Use it to maintain easy starting, smooth idling, and consistent running on equipment such as lawn mowers, brushcutters, chainsaws, generators, pumps, and compactors that specify an RDJ7Y plug. Made by Champion, it is a practical, serviceable choice for routine maintenance where a 14 mm spark plug is required.
