The Audi S4 has spent multiple generations as the performance-oriented sibling to the A4, offered as a sedan or Avant with turbocharged or supercharged six-cylinder power depending on the model year. Our S4 accessory range covers illuminated LED door sills that light up on entry, power liftgate and electric tailgate kits for the Avant's cargo area, electric soft-close door kits, and stainless emblem sets for the grille, fender, and tailgate. All pieces are aftermarket and designed to fit the S4 without permanent modification.
The S4's mix of sedan and Avant body styles across its generations means our accessory range spans both convenience upgrades and exterior detailing, chosen to work with the car's factory mounting points.
LED door sills add an illuminated strip along the entry threshold, typically wired to activate when a door opens. Soft-close door kits add a motor-driven final pull so doors settle shut quietly rather than needing a firm slam.
Power liftgate kits give the S4 Avant one-touch trunk access, while stainless emblem sets refresh the grille, fender, and tailgate badges with a sharper factory-style finish.
Door sill and soft-close kits are engineered around the S4's factory door and threshold hardware, and emblem sets are made from stainless steel for long-term durability. Because the S4 has been built on several generations (B8, B9, and beyond), confirm your model year when ordering.
No, most kits use adhesive-backed sill covers that sit over the factory sill and connect to a low-draw wiring harness.
Liftgate kits are typically designed for the Avant's larger tailgate mechanism; sedans use a separate trunk lid, so check the product listing for your body style.
