Frequently Asked Questions

Q: What does an ignition coil do? A: An ignition coil steps up the low battery voltage to the high voltage required by the spark plug so the plug can create the spark that ignites the air-fuel mixture in a gasoline engine.

Q: How do I confirm this 6-coil set will fit my vehicle? A: Compare the existing ignition coil part number on the vehicle against 0221504470, and confirm the complete BMW model designation such as 325i, 328i, 335, 525, 528, 530, 535, X3, X5, or X6 matches the application, before purchase.
