Expert Recommendation
Why BERU? B38 engines reflect the slightest malfunction in the ignition system as a "drive warning" on the display. BERU is one of the most reliable brands recommended by BMW for this engine group.
Installation Tip: Always use a torque wrench when tightening the spark plugs (Recommended: 23±3 Nm). Over-tightening can cause the porcelain to crack, while under-tightening can lead to compression leaks. It is also recommended to check the **Ignition Coils** during replacement.
