AUDI RS4 B9 LCI 2020+ PERFORMANCE PARTS AND STYLING UPGRADES

The facelift Audi RS4 B9 LCI, also commonly known as the Audi RS4 B9.5, combines exceptional everyday practicality with quattro traction, twin-turbocharged performance and unmistakable RS Avant styling. Introduced from 2020, the updated RS4 features a more aggressive exterior design and remains one of the most desirable European performance estates for tuning, exhaust upgrades and carbon fibre customisation.

Our collection of Audi RS4 B9 LCI performance parts brings together carefully selected upgrades for daily-driven cars, refined OEM+ projects and more extensively modified builds. From valved exhaust systems and high-flow downpipes to cold air intakes, cooling components and carbon fibre styling parts, EURO TUNED offers solutions designed to enhance the sound, appearance and driving experience of the facelift RS4.

PERFORMANCE UPGRADES FOR THE AUDI RS4 2.9 TFSI

The twin-turbocharged 2.9 TFSI platform offers strong potential for carefully selected airflow, exhaust and cooling modifications. Popular Audi RS4 B9 performance upgrades include performance exhaust systems, downpipes, cold air intakes, turbo inlet components, intercoolers and supporting ECU or TCU software.

Components can be installed individually or combined to create a more complete performance package. The most suitable setup will depend on the intended use of the vehicle, desired sound level, local emissions requirements and whether the car remains on factory software or receives additional tuning.

Common upgrades for the facelift RS4 include:

  • Audi RS4 B9 LCI valved exhaust systems
  • High-flow catted and catless downpipes
  • Audi RS4 B9 cold air intake systems
  • Turbo inlet and intake pipe upgrades
  • Intercoolers and supporting cooling components
  • Carbon fibre exterior styling parts
  • Gloss black grilles and exterior trim
  • Interior and driver-focused accessories
AUDI RS4 B9 LCI PERFORMANCE EXHAUST SYSTEMS

An Audi RS4 B9 LCI performance exhaust is one of the most effective upgrades for transforming the character of the 2.9 TFSI engine. A high-quality aftermarket system can provide a deeper, sharper and more distinctive exhaust note while enhancing the appearance of the rear bumper and exhaust outlets.

Valved Audi RS4 exhaust systems provide additional control over the volume and tone of the vehicle. With the valves closed, the exhaust can retain a quieter and more refined sound for motorway journeys, early starts and everyday driving. Opening the valves creates a louder and more aggressive tone when a stronger performance sound is preferred.

Depending on the product and vehicle specification, available exhaust options may include:

  • Valved cat-back exhaust systems
  • Rear-section and axle-back exhaust upgrades
  • Resonated and non-resonated configurations
  • Systems compatible with factory or upgraded downpipes
  • Polished, gloss black, titanium-style or carbon fibre exhaust tips
  • Exhaust upgrades for OPF-equipped and non-OPF vehicles

The final exhaust volume and sound profile can be affected by catalytic converters, OPF or GPF filters, resonators, downpipes and engine software. These factors should be considered before choosing the most suitable system.

AUDI RS4 B9 LCI DOWNPIPES

An upgraded Audi RS4 B9 downpipe is designed to reduce restriction after the turbochargers, increase exhaust volume and support further tuning potential. Downpipes are commonly installed alongside a performance exhaust and compatible engine software as part of a complete airflow and exhaust upgrade package.

High-flow catted downpipes offer a balance between improved exhaust flow, stronger sound and everyday usability. Catless downpipes provide maximum flow and a more aggressive exhaust note but may not comply with emissions, inspection or public-road regulations in every country.

Fitment and software requirements can vary between OPF-equipped and non-OPF vehicles. Customers should check local regulations and confirm compatibility with their exact vehicle specification before installing an emissions-related component.

COLD AIR INTAKES AND TURBO INLET UPGRADES

An Audi RS4 B9 cold air intake can enhance induction sound and support improved airflow into the twin-turbocharged engine. Intake upgrades are particularly popular with owners looking for stronger turbocharger sound, a more engaging acceleration experience and a premium engine-bay appearance.

Depending on the design, an intake system may replace the original airbox, filters, intake pipes or turbo inlet components. Selected products feature carbon fibre construction, combining performance-focused airflow with a high-end visual finish.

Turbo inlet upgrades can also help reduce restriction before the turbochargers and complement a larger intake system. Compatibility with factory sensors, engine covers and existing modifications should always be confirmed before purchase.

INTERCOOLERS AND COOLING UPGRADES

A larger Audi RS4 B9 intercooler can help manage charge-air temperatures during repeated acceleration, spirited road driving and demanding performance use. Improved cooling can support more consistent power delivery, particularly on tuned vehicles operating with increased boost.

Cooling upgrades may include larger intercoolers, charge pipes, auxiliary cooling components and related airflow improvements. Fitment with factory sensors, hoses, crash structures, bumper components and existing aftermarket parts should be checked before ordering.

AUDI RS4 B9 LCI CARBON FIBRE PARTS

The redesigned front bumper, wide arches and aggressive Avant bodywork of the facelift RS4 provide an excellent foundation for Audi RS4 B9 LCI carbon fibre parts. Carefully selected exterior components can create a lower, wider and more motorsport-inspired appearance while complementing the original RS design.

Popular Audi RS4 B9.5 styling upgrades may include:

  • Audi RS4 B9 LCI carbon fibre front splitters
  • Front bumper corner extensions and canards
  • Audi RS4 carbon fibre side skirt extensions
  • Carbon fibre rear diffusers
  • Roof spoiler extensions
  • Carbon fibre mirror covers
  • Gloss black or carbon fibre front grilles
  • Carbon fibre exhaust tips
  • Replacement exterior trim and aerodynamic accessories

These components can be installed individually for a subtle OEM+ finish or combined into a more complete Audi RS4 B9 LCI carbon fibre styling package. Matching the front splitter, side skirts, roof spoiler and rear diffuser helps create a consistent appearance across the entire vehicle.

FRONT SPLITTERS AND FRONT-END STYLING

An Audi RS4 B9 LCI front splitter adds definition to the lower section of the facelift bumper and creates a more planted front-end appearance. Available designs range from clean factory-inspired additions to larger motorsport-style splitters for more aggressively modified RS4 builds.

Front bumper corner extensions and canards can provide additional visual detail around the air intakes and help create a wider-looking front profile. Choosing parts designed specifically for the LCI bumper is essential, as pre-facelift RS4 exterior components are not automatically compatible with 2020+ vehicles.

SIDE SKIRT EXTENSIONS FOR THE RS4 AVANT

Audi RS4 B9 LCI side skirt extensions visually lower the side profile and help connect the styling between the front splitter and rear diffuser. They are especially effective on the RS4 Avant, where the long roofline and pronounced arches already create a strong performance-estate silhouette.

Side skirt upgrades may be available in carbon fibre, gloss black or other finishes. Selecting a design that matches the weave and finish of the front and rear styling components helps produce a more complete, professionally finished result.

AUDI RS4 B9 LCI REAR DIFFUSERS

An Audi RS4 B9 LCI rear diffuser transforms the lower rear bumper and enhances the area surrounding the exhaust outlets. Different diffuser styles may suit factory exhaust trims, upgraded exhaust tips or complete aftermarket exhaust systems.

Customers planning an exhaust conversion should confirm that the diffuser is compatible with the intended outlet shape and position. Fitment can also be affected by towing equipment, market-specific bumpers and existing rear styling modifications.

ROOF SPOILERS AND REAR-END ACCESSORIES

An aftermarket Audi RS4 B9 roof spoiler or spoiler extension can add a more aggressive finish to the rear of the Avant while retaining its practical estate design. Options may range from subtle extensions to more pronounced carbon fibre styles.

Pairing the roof spoiler with a matching rear diffuser and carbon fibre mirror covers helps maintain a balanced styling theme. Matching carbon weave direction and surface finish is also important when combining components from different areas of the vehicle.

GRILLES, MIRROR COVERS AND EXTERIOR TRIM

Smaller styling changes can make a significant difference to the overall appearance of the facelift RS4. Audi RS4 B9 LCI gloss black grilles, carbon fibre mirror covers and replacement trim pieces can reduce factory chrome details and create a cleaner, more modern design.

These accessories are ideal for customers looking to personalise their vehicle without replacing major body panels. They can also be installed alongside larger aerodynamic components to create a complete exterior transformation.

AUDI RS4 B9 LCI INTERIOR UPGRADES

The cabin can also be personalised with Audi RS4 interior accessories designed to create a more distinctive and driver-focused environment. Depending on product availability, upgrades may include carbon fibre steering wheel trim, extended paddle shifters, replacement steering wheels, gear selector components and centre-console accessories.

Interior styling parts allow owners to carry the exterior carbon fibre theme into the cabin while improving the appearance and feel of the controls used on every journey.

CHOOSING THE CORRECT AUDI RS4 B9 LCI PARTS

Before purchasing Audi RS4 B9 LCI aftermarket parts, it is important to confirm compatibility with the exact vehicle specification. Fitment may vary according to:

  • 2020+ facelift B9 LCI or B9.5 model
  • Production year and market specification
  • Left-hand-drive or right-hand-drive configuration
  • OPF or GPF equipment
  • Factory sports exhaust or standard exhaust
  • Original bumper, diffuser and exhaust configuration
  • Existing performance or exterior modifications
  • Vehicle software and tuning level

Pre-facelift and facelift RS4 models use different bumper designs and may require different exhaust or styling components. Always check the complete product title, description and listed compatibility before ordering.

Customers who require additional fitment confirmation can contact EURO TUNED with their production year, registration number, vehicle specification or VIN.
