Typically, a 4-cylinder engine will have four spark plugs, with one spark plug per cylinder. These vital components are responsible for igniting the air-fuel mixture within each cylinder through an electrical spark, hence initiating combustion. However, certain modern or high-performance 4-cylinder engines may employ a dual spark plug setup per cylinder, aiming to improve combustion efficiency, increase power, reduce emissions, and enhance fuel economy. Therefore, while the standard setup includes four spark plugs for a 4-cylinder engine, configurations might vary depending on the engine's design and performance requirements. It's always a good idea to consult your vehicle's manual or a professional for specifics about your engine.
