2017–2018 Audi A4 S-Line / S4 B9 Sedan 3-Piece Front Lip Kit – Carbon Fiber

Sharpen the front end of your Audi A4 S-Line or S4 B9 Sedan with this three-piece carbon fiber front lip kit. Molded to follow the factory bumper lines, it adds lower definition and visual width for a wider, more planted, performance-driven stance without overdoing it.

Build

• Material: Genuine carbon fiber, vacuum moulded for consistent fitment, lightweight yet structurally strong, with an authentic weave appearance over carbon-look alternatives
• Manufacturing: Precision 3D-engineered for accurate bumper fitment
• Surface finish: Smooth gloss carbon finish with a UV-protected clear coat for long-term durability
• Configuration: Three-piece splitter kit for the lower front bumper

Design & Finish

• Aggressive stance: Three-piece layout enhances the lower bumper profile for a wider, more planted front-end look
• Carbon aesthetic: Gloss carbon weave and clear coat deliver premium contrast against the factory paint
• Factory-style integration: Precision-molded to the contours of the factory S-Line / S4 bumper for a clean, seamless fit

Fitment

• 2017–2018 Audi A4 S-Line B9 Sedan (4-door)
• 2017–2018 Audi S4 B9 Sedan (4-door)
• Fits the S-Line / S4 front bumper only — not compatible with the standard non-S-Line A4 or aftermarket bumpers

Package Contents

• 3 × carbon fiber front lip sections
• Mounting screws and adhesive tape for installation

Installation

• Two mounting options: Fits using the included mounting screws and adhesive tape for a secure fit across all three sections
• Drilling may be required: If you use the screw option, screw fixing pierces the bumper, so it is a permanent modification rather than a reversible fit
• Surface prep: If using adhesive tape, thoroughly clean, degrease, and dry the front bumper before fitting to ensure maximum adhesion
• Alignment: Dry-fit all three sections together and check spacing and symmetry across the bumper before committing to either method
• Professional installation recommended — with three separate sections, correct spacing and a balanced, symmetrical finish are harder to achieve unaided

Before You Install

• Confirm your car is an A4 S-Line or S4 B9 Sedan (2017–2018) before ordering — this will not fit the standard non-S-Line A4
• Plan the three-piece layout before you start — dry-fit and mark positions so the sections line up evenly
• If using screws, mounting is permanent — confirm placement carefully before driving any screws, as holes cannot be undone
• Front lips sit low and are exposed to kerbs, driveway ramps, and road debris — take care when parking nose-in
