Volkswagen B5, Audi, New Lingyu Ignition Coil 078905104 Fits old classic models

If your car experiences power loss on acceleration, idle vibration, rising fuel consumption, or engine check light, it is likely ignition coil aging causing insufficient ignition energy and misfire. The ignition coil normally converts low voltage to high voltage to precisely ignite the mixture and ensure smooth engine operation. This product with OEM number 078905104 fits older 4-cylinder VW platforms such as B5 and New Leones (A4/A6 era). Be sure to disconnect the battery negative terminal during installation and ensure tight connections between coil and spark plug to avoid high-voltage leakage.
