These small but vital parts ignite the air-fuel mixture in the engine cylinders, ensuring optimal combustion and engine power.

If you notice any of these symptoms, it’s a good idea to have your spark plugs inspected by a professional technician. Timely replacement not only improves engine performance but also prevents potential damage to other engine components.
