Description
Overview:
The Champion RJ17LM is a 14 mm (0.55 in) small‐engine spark plug designed for reliable ignition in petrol-powered equipment. It uses a durable metal shell with a ceramic insulator and a standard single ground electrode to deliver a clean, consistent spark. The RJ17LM helps ignite the fuel-air mixture for smooth starting and stable running. It suits a wide range of garden and light construction machinery, including lawnmowers, generators, water pumps, plate compactors, tillers, and other small engines typically found on site or at home. Manufactured by Champion, it is a practical replacement where a 14 mm thread plug is specified. Model: RJ17LM.
