£11.53
The NGK YE13 (8643) is a glow plug for diesel engines. It provides heat for cold starting, and the heater element is sealed inside a sheath. The stated specifications include an 11.5 V marked voltage, an 8 mm hex and an 8 mm thread diameter.
A quick, even glow is described as improving cold-weather starting and reducing white smoke and rattle during the first minutes of running. On later engines, glow plugs can also support the post-heating phase while the engine warms through.
