This is a genuine BMW Ignition Coil, part number 12138657273, engineered to meet the exact specifications of your BMW vehicle. An ignition coil is a vital component of your car's ignition system. It functions as a transformer, converting low voltage from the battery into the high voltage required to create an electric spark across the spark plug gap. This spark ignites the fuel-air mixture in the combustion chamber, powering your engine. Over time, ignition coils can degrade due to heat and vibration, leading to misfires, rough idling, reduced fuel efficiency, and difficulty starting. Replacing a faulty ignition coil with a genuine BMW part ensures compatibility and restores your engine's performance and reliability. This ignition coil is designed for a perfect fit and seamless integration with your BMW's electrical system, guaranteeing the quality and durability you expect from BMW.
