BMW F30 F31 3 Series M Performance Lower Sill Trims in Matt Black - Genuine OE Pair

Elevate the side profile of your 3 Series with BMW factory M Performance lower sill trims in matt black. This genuine OE pair is engineered specifically for the F30 Saloon and F31 Touring for a tight, precise fit that looks straight from the showroom. The result is a lower, broader stance with sharper lines and a premium OEM plus finish that complements M Sport styling and standard models alike.
