Revo OEM+ Intake System

Get impressive performance benefits without compromising on the factory look of your engine bay. Revo OEM+ Air Intake Systems utilise the existing airbox, replacing any restrictive components with parts precisely engineered to reduce turbulence and improve airflow.

The B9 Audi A4 shares the same airbox as the higher-powered S4 and RS4 models and performed well during initial testing of volume and flow. This air intake system upgrade includes a Revo foam filter and a flush-fit silicone hose to minimise air restriction and turbulence, improving airflow and giving you access to more power.

Key Features

• Increased Airflow by up to 20%
• Three-layer foam filter
• Stepped Silicone Hose
• +11Hp and 13NM performance gains

Kit Contents

• Revo ProPanel Filter
• Revo Silicone Hose

Air Filter – The standard paper filter found in most vehicles performs well under normal conditions, however, with the increased power it becomes a major choking point in the system. Revo filters work by trapping dirt particles within each of the oiled foam layers while allowing air to negotiate its way through, reducing restriction and offering much longer service intervals. The new Revo filter features an OEM top plate, allowing a direct fit replacement for the stock airbox.

Silicone Hose – The plastic hose on the stock system is designed with a corrugated style to flex with the engine movement, while this has its place it also causes a large amount of turbulence as the airflow doesn’t have a smooth direct path to the turbo. We designed the silicone hose with stepped internals to ensure a flush fit, and to minimise turbulence while still allowing for engine movement.

Self-Seal Takeoff – The OE B9 A4/A5 intake hose has a small vacuum take-off used to supply vacuum to various components of the engine. To replicate this, the Revo B9 A4/A5 intake hose utilizes a threaded self-seal barb. This machined configuration offers a better aesthetic and more durability than typical plastic and glued couplers.
