What are glow plugs? A glow plug is an equivalent to a spark plug for a diesel engine. As diesel fuel works differently, by being put under high pressure to cause heat and combustion, the technology of a glow plug is a little different to a spark plug.
In cold temperatures glow plugs assist the heating process, basically they are small heaters. Glow plug removal followed by a simple glow plug test can find out if they are not heating properly, if more than one glow plug is faulty then a diesel engine won’t start.
Our glow plug range includes leading brands trusted by diesel specialist professionals everyday, like NGK, Blue Print, Bosch and Denso, as well as glowplugs themselves, we also stock glow plug relays, sockets and reamers.
