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 minimize 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.
