Petrol car spark plugs are an essential component of the ignition system in most internal combustion engines. These small devices deliver an electric spark that ignites the fuel and air mixture in the engine's cylinders, allowing the vehicle to start and run smoothly. While spark plugs may seem like a minor part of a car's engine, they can have a significant impact on performance, fuel efficiency, and emissions. High-quality spark plugs can help to improve acceleration, reduce fuel consumption, and minimise harmful pollutants.
