These parts , known as spark plugs , are crucial components in the ignition system of the gasoline engines in the aforementioned JAC vehicles. Their primary function is to generate a powerful electrical spark within the engine's combustion chamber at a precise moment. This spark ignites the compressed air-fuel mixture, creating the explosion necessary to drive the piston and generate the power required to move the vehicle. Using genuine spark plugs ensures a long lifespan and the correct ignition type for your engine.
If you notice difficulty starting the engine, or noticeable vibration and jerking, especially at idle speeds (standing still), or an increase in fuel consumption and weakness in acceleration, this often indicates damage or wear to the spark plugs and the need for periodic replacement.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
