5. Principis de funcionament
The spark plug is responsible for igniting the air-fuel mixture in the engine's combustion chamber. When high voltage is applied to the center electrode, it creates a spark that jumps across the gap to the ground electrode, initiating combustion. The ACDelco R42XLS is designed to provide a consistent and powerful spark, contributing to efficient fuel consumption and smooth engine operation.
6. Manteniment
Spark plugs are wear items and require periodic inspection and replacement. The lifespan of a spark plug can vary based on engine type, driving conditions, and spark plug material. While the ACDelco R42XLS is designed for durability, regular checks are recommended.
