AUDI S4 B9 PERFORMANCE PARTS
The Audi S4 B9 combines everyday practicality, quattro traction and turbocharged V6 performance with refined S-model styling. This collection focuses on selected 2017–2019 pre-facelift vehicles, offering compatible upgrades for exhaust sound, engine airflow, cooling and exterior appearance.
Available products may include Audi S4 B9 exhaust systems, downpipes, cold air intakes, turbo inlet components, cooling upgrades, carbon fibre front splitters, side skirts, rear diffusers, spoilers, replacement grilles, mirror covers, engine bay parts and interior accessories.
S4 B9 SALOON AND AVANT FITMENT
Compatible products may be available for selected Audi S4 B9 Saloon and Avant models where specifically listed. Both body styles share many front-end and mechanical components, but rear diffusers, exhaust sections, boot spoilers, roof spoiler extensions and other rear-body parts can differ.
Standard A4, S line and full S4 models also use different bumpers, grilles, rear valances and exhaust arrangements. Parts should therefore be selected specifically for the S4 and exact body style.
AUDI S4 B9 EXHAUST AND PERFORMANCE UPGRADES
An Audi S4 B9 performance exhaust can provide a deeper and more engaging V6 soundtrack while enhancing the factory quad-exit rear appearance. Depending on the product, compatible options may include valved cat-back systems, centre sections, downpipes and alternative exhaust tips.
Selected models may also support cold air intakes, turbo inlet upgrades and enhanced cooling components. These upgrades may reduce airflow restriction, improve intake sound or support vehicles running suitable engine and transmission software.
High-flow catted or catless downpipes may affect emissions compliance, warning lights and software requirements. Local road and inspection regulations should always be checked before installation.
AUDI S4 B9 CARBON FIBRE PARTS
Audi S4 B9 carbon fibre parts can complement the understated S-model bodywork and create a lower, sharper and more performance-focused appearance. Popular upgrades may include front splitters, side skirt extensions, rear diffusers, boot or roof spoilers, mirror covers, replacement grilles and engine bay accessories.
Selected products feature genuine 2x2 twill 3K carbon fibre for the visible woven finish rather than printed, wrapped or hydro-dipped carbon-look material. Exact construction is stated on each product page.
CHOOSING THE CORRECT AUDI S4 B9 PARTS
Before ordering Audi S4 B9 aftermarket parts, confirm the production year, Saloon or Avant body style, engine specification, factory bumper and original exhaust arrangement. OPF equipment, exhaust valve controls, cameras, radar modules, parking sensors and existing modifications may also affect compatibility.
Later B9.5 facelift models use different lighting, bumpers, grilles, electronics and exterior details, so B9 and B9.5 styling parts are not automatically interchangeable.
