Purpose and function of the side skirt

The left outer side skirt plays an important protective and aesthetic role in the lower part of the body. It is responsible for:

• protecting the sill against stone chips, dirt, and external factors,
• providing a clean finish to the side body line,
• maintaining the vehicle's factory appearance after body and paint repairs.

The element is matched to the geometry of the Audi A4 B7 body, which facilitates installation and allows for an even transition line between the doors and the sill.

Brilliant Red Y3J color and visual matching

The factory Brilliant Red – Y3J color is a characteristic, intense shade of red used in Audi models. Using a side skirt in the same paint code allows you to:

• minimize color differences between the new component and the rest of the body,
• limit the scope of additional painting to the absolute minimum,
• maintain a consistent, aesthetic look of the side bodywork.

For workshops and private users, this means faster repair completion and a more predictable visual result.

Placement on the vehicle and installation aspects

The side skirt is designed for installation on the left side of the vehicle, in the lower body area. Proper placement is important both for fitting with other body components and for correct water drainage and sill protection.

The original design for the Audi A4 B7 facilitates fitting to the factory mounting points. During installation, it is recommended to:

• thoroughly clean and apply anti-corrosion protection to the sill surface,
• check the condition of clips and fasteners before final seating of the side skirt,
• inspect the gaps between the side skirt and the doors on both sides of the vehicle.

Characteristics of the used product

The item comes from the segment of used original Audi parts, which means it retains factory geometry and compatibility with the A4 B7 body. This type of component is a good choice for repairs where OEM compliance and cost-effective replacement are prioritized.

Before installation, it is worth verifying the condition of the paint surface and potentially planning local corrections or polishing to perfectly match the appearance of the side skirt to the rest of the body.
