Audi A6L 2.4 C6 Red Top Ignition Coil 06E905115A Stable Ignition Performance

When Audi A6L 2.4 C6 shows rough idle, weak acceleration, high fuel consumption, and sometimes a misfire indicator on the engine fault light, the ignition coil is typically aging or ruptured and cannot reliably transfer high voltage. This red-top ignition coil (OEM 06E905115A) converts low voltage to high voltage to ignite the air-fuel mixture, ensuring smooth operation and strong power. Suitable for Audi A6L 2.4 C6 (2005–2011) and other 4-cylinder models on the same platform. Installation must be done with the car cold; ensure the ignition coil connector mates securely with the spark plug to avoid secondary faults.
