Petrol engines, the spark plugs start the combustion phase, creating the spark which ignites the air/fuel mix. Diesel engines, on the other hand, function using a self-ignition system: the injected fuel ignites when the air/fuel mix reaches the self-combustion temperature. The glow plugs are used to prepare the correct thermal conditions to achieve the spontaneous combustion of the mixture.
Mopar® spark plugs and glow plugs guarantee lower fuel consumption and emissions thanks to perfectly efficient combustion - as well as better performance, excellent driving comfort and engine flexibility.
Difficult ignitions, uneven engine performance, power loss and increased fuel consumption can all be signs of a need to check the spark plugs or glow plugs. Perfectly functioning spark plugs and glow plugs play an important part in optimising engine performance and catalytic converter efficiency.
