Genuine BMW Lower Engine Cover Support Bracket – Part No. 51757309591

Secure your BMW’s lower engine cover properly with this Genuine BMW support bracket. Designed to hold the belly pan and front lower panel firmly in place, it eliminates buzzing and sagging, restores tidy undercarriage airflow, and helps protect vital components from road spray and debris. Part number 51757309591. Compatible with BMW F-series 1 Series, 2 Series, 3 Series and 4 Series models including 125i, 228i, 335i and 440i.

We’ve fitted this on our own vehicles and for many customers at MJ Modifications in Warwickshire. The fit is precise, the rattle goes, and the lower guard sits exactly as it should. Feedback is consistently excellent with a factory-fresh result and a neat, quiet front underfloor area.

Why this OE support is a smart choice

• Original BMW component for perfect alignment and long-term durability
• Locks the lower engine guard in place to stop vibrations, scraping and drooping
• Helps shield the sump and ancillaries from stones, salt and standing water
• Restores designed airflow under the front end for a smoother, quieter drive
• Tried and tested by MJ Modifications with great customer satisfaction

Typical issues this resolves

• Loose belly pan or hanging lower panel
• Rattling or drumming noises from the front underside
• Broken, missing or worn mounting bracket for the lower engine cover
