Technical Characteristics and Fitment

The left sill in Estoril Blau Metallic - B45 is specifically designed for BMW F30 and F31 body types, ensuring a precise fit to the body's contours. The original mounting geometry facilitates installation in factory points, without the need for modifications or forcing the part into place. This preserves the correct body line, and the gaps between elements remain even.

Function and Role of the Sill Moulding

The sill moulding performs several important structural and functional roles:

• protects the lower part of the body from mechanical damage and road debris,
• visually stabilizes the vehicle's side line, improving aesthetic appeal,
• allows for proper alignment of the door edges with the sill,
• supports the maintenance of the original aerodynamics of the vehicle's side section.

By using an original sill moulding, you maintain stylistic consistency with other body elements and proper adhesion of seals and trims.

Estoril Blau Metallic - B45 Color

The Estoril Blau Metallic - B45 finish is characteristic of sportily configured BMW 3 Series models. The appropriate structure and shade of the paint allow for an aesthetically pleasing integration of the sill into the car's side line, without visible color differences compared to originally painted elements (provided the paintwork on the vehicle is in good condition). This is particularly important when replacing a single part, where you want to maintain a cohesive appearance without repainting the entire side.

Why Choose a Used OEM Sill Moulding

Choosing a used OEM part from the BMW Sill Mouldings category is a solution that combines cost control with the preservation of factory quality. An original part ensures:

• dimensional compatibility with the F30/F31 body,
• factory mounting points,
• stylistic consistency with other body elements,
• no need for adaptation of aftermarket parts with different geometry.

Application and Part Selection

The left sill in Estoril Blau Metallic - B45 is suitable for both accident repairs and for replacing worn or damaged elements of the vehicle's side body. Before purchasing, it is advisable to verify compatibility with the specific 3 Series body version to ensure proper fitment with the doors, wheel arches, and underbody covers. A used OEM part helps maintain the car's original character, which is important for both daily use and potential future resale of the vehicle.
