All Bosch ignition coils are built to achieve or exceed OE specifications and are known industry-wide for their reliability and performance. Bosch ignition coils convert low voltage into high ignition system voltage, creating an electric spark sent to the spark plugs which ignites the fuel.

Bosch DuraSpeed sheathed-element glow plugs heat up more quickly and retain their glow longer, ensuring that modern diesels are instantly ready to go – even at temperatures as low as –28 °C. A controlled post-glow phase ensures low emissions and a quiet engine, whilst intelligent energy management relieves the strain on the electrical system and battery. And as a systems provider, Bosch guarantees that every sheathed-element glow plug operates seamlessly inside the engine management system.
