Overview

This system replaces the factory airbox lid, filter, and air scoop with high-flow carbon fibre components to allow the engine to draw in more cool, dense air. The result is claimed genuine power gains and faster turbo response.
Show original supplier description
The Racingline Carbon Fibre Air Intake System is engineered to enhance performance for the Audi RS4 (B9) and RS5 (B9) models equipped with the 2.9 V6 TFSI twin-turbo engine. By upgrading the restrictive factory airbox lid, filter, and air scoop with high-flow carbon fibre components, this system facilitates a greater volume of cool, dense air into the engine. Central to the system is Racingline’s TriFoam™ filter, a triple-layer laminate of open-cell polyurethane foam handmade in the UK. This filter offers a balance of high airflow and effective filtration. The design retains the factory lower airbox, which is positioned to draw cool air, ensuring a straightforward installation and a non-intrusive fit. This intake system is designed for the Audi RS4 (B9) and RS5 (B9) models. It is confirmed to fit the Audi A4 B9 Avant (8W5, 8WD) RS4 TFSi quattro (DECA) from 2017-2025 and RS4 TFSI quattro (DECC) in 2024. It also fits the Audi A5 (F53, F5P) RS5 TFSI quattro (DECA) from 2017-2025 and RS5 TFSI quattro (DECC) from 2024-2025, as well as the A5 Sportback (F5A, F5F) RS5 TFSI quattro (DECA) from 2018-2025 and RS5 TFSI quattro (DECC) from 2024-2025. Customers are responsible for verifying fitment for their specific vehicle. The kit includes a carbon fibre airbox lid, a carbon fibre air scoop, a TriFoam™ high-flow air filter, and all necessary fittings and hardware for installation. The genuine carbon fibre components feature a deep, lacquered finish for a premium look. Users can expect a richer induction note under acceleration without it being intrusive during cruising.
