NGK Glow Plug - Y-112T - 6327

A glow plug's primary function is to pre-heat the combustion chamber in a diesel engine, making it easier to start, especially in cold temperatures. It ensures the air-fuel mixture reaches ignition temperature quickly.

Common signs include difficulty starting in cold weather, rough idling, increased exhaust smoke, and a glow plug warning light on the dashboard.
