BMW Ignition Coil - Bremi 12137841556

Product Information

Direct ignition coils are responsible for generating and transferring power directly to the spark plug, ensuring efficient combustion. Over time, especially with higher mileage, ignition coils can lose efficiency, leading to misfires, reduced power, and poor fuel economy. While it's possible to replace ignition coils individually, it's recommended to replace all coils at once if one fails to restore optimal performance and reliability.

These direct ignition coils are mounted directly over each spark plug (coil-on-plug design), eliminating the need for traditional spark plug wires. This system is standard on most modern vehicles due to its benefits for packaging, emissions, and maintenance. Routine service is minimal, typically limited to spark plug changes and occasional coil replacement.

Common symptoms of ignition coil failure:

• Reduced fuel efficiency
• Loss of power
• Engine misfires
