The NGK Y-103-2 is a glow plug with a marked voltage of 9.5 V. Its specifications include a 12 mm hex, 10 mm thread diameter and 1.25 mm thread pitch.
The overall length is 70 mm, the threaded terminal is 4 mm, and the glow tip is 19 mm long. The stated installation torque is 15–20 Nm.
Glow plugs provide heat for a diesel engine's cold start. The heater element is sealed inside a metal sheath, or a ceramic sheath on fast-heating types. The element reaches well over 800°C within seconds after the ignition is switched on.
A quick, even glow improves cold-weather starting and reduces white smoke and rattle during the first minutes of running. On later engines, glow plugs also support the post-heating phase while the engine warms through.
