Added NGK glow plug sizes

175 new NGK spark plugs added to diesel engine glow plug selection catalog

For decades, NGK SPARK PLUG's experience in glow plug development has been appreciated by diesel vehicle owners and automakers around the world. NGK glow plugs perform reliably in the toughest conditions.

To ensure that the autoignition temperature is reached even under the most difficult conditions, such as freezing temperatures or cold starts, the combustion chamber must be preheated. This process is carried out by a glow plug. The glow plug works like an immersion heater and converts electrical energy into heat, heating up to extremely high temperatures (up to 1350 °C).
