Spark & Glow Plugs

Spark & Glow Plugs bring together two critical engine components: spark plugs for petrol engines and glow plugs for diesel engines. This category covers replacement plugs and diagnostic-ready variants. Spark plugs vary by electrode material (copper, platinum, iridium), heat range, electrode count, thread size and reach, all influencing starting reliability and smooth running. Glow plugs differ in heater type and electrical resistance, designed to preheat cylinders for cold starts. When comparing, check your engine code and ignition system, then match thread diameter, reach, and heat or resistance requirements. Consider lifespan and installation torque as well. A careful match supports easier starts, steadier idling, and improved engine efficiency.
