Testing spark plugs is a crucial aspect of engine maintenance, ensuring optimal performance and fuel efficiency. Spark plugs ignite the air-fuel mixture in the engine’s cylinders, creating the combustion that powers the vehicle.
Regular spark plug testing helps identify worn or fouled plugs, which can lead to engine misfires, reduced power, and increased emissions. By replacing faulty spark plugs promptly, you can maintain engine health, improve fuel economy, and prevent costly repairs down the road.
