Revo Audi A4/A5 (B9) 2.0 TFSI OEM+ Air Intake System
£210.00
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
- Revo Takeoff
- Stainless Steel Clamps
AIRFILTER
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.
PERFORMANCE
Testing was carried out with consistent conditions on both the OEM intake and the Revo OEM+ Intake System on a 2017 Audi A4 B9 2.0 TFSI Quattro (252ps) running Revo Performance ECU Software and hardware. While dyno testing for performance gains, VCDS software was used to log airflow with a full AEM logging suit used to monitor temperatures. The Revo Intake increased vehicle performance, especially higher in the rev range, highlighting the performance benefits over the stock components.
AIRFLOW
Testing of the stock unit back to back against the Revo OEM+ kit on a full flow bench was carried out to highlight the largest restrictions in the system. The Revo OEM+ Intake system had far less restriction than the OE unit, at 480CFM the stock unit was seeing 619mmwg restriction while the Revo unit only saw 530mmwg some 14% less restrictive. At low flow rate the Revo intake provided up to 20% less restriction, improving throttle response. The graph below shows the flow test and comparison between the OE and Revo intakes.

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
