Purpose and Fitment

The sill trim is specifically designed for facelifted (LCI) BMW 3 Series E90/E91 models, intended for the left side of the vehicle. The OEM construction guarantees proper sill edge alignment, correct mounting points, and compatibility with factory covers and body elements in this area. This allows the part to be installed as a replacement for a damaged trim without modifications.

Black Sapphire Metallic Color and Finish

The Black Sapphire Metallic - 475 finish is characteristic of many BMW configurations, so the trim blends well with the body's styling line. The metallic paint coating provides color depth and improves visual consistency with doors, fenders, and bumpers in the same shade. In case of accident repairs or localized bodywork, this allows for minimal repainting or easier color matching during potential coating refresh.

Characteristics of a Used Part

The sill trim is a dismantled part, meaning it is an original, used BMW component. Such parts are often chosen for body repairs because they retain factory geometry, and their construction complies with the vehicle manufacturer's requirements. A used sill trim can be a cost-effective solution while maintaining an appropriate level of quality and fitment.

Benefits of Using an Original Sill Trim

Using an original Black Sapphire Metallic sill trim offers a number of practical advantages:

• maintaining the factory body line and proper fitment of elements in the sill area,
• compatibility with factory mounting points on the left side of the vehicle,
• reducing the scope of body and paintwork due to the matched color,
• enabling aesthetic replacement of a damaged part without altering the sill structure.
