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.   FITMENT   Manufacturer Model Engine Variant Year Audi A4 2.0TFSI B9 252PS 2015> Audi A5 2.0TFSI B9 252PS 2015> Audi Q5 2.0TFSI B9 252PS 2015> *Note: Plastic airbox lid not included in the kit.   DOCUMENTS The following documents are available to view: FITTING INSTRUCTIONS Download the Revo Audi B9 2.0 TFSI Intake Instructions

The Audi RS6 and RS7 are without doubt quick in their purest form, add Revo Stage 1 and 2 software however, they quickly become supercar killers. Giving the cars an even further boost in their already staggering power figures, we turned our attention to developing an upgrade for the air intake system. Testing found that the RS air-box had a tremendous amount of potential, with only a few key areas that caused restriction.The new direct replacement kit includes a Revo foam filter, stepped silicone hoses and an aluminium tag. We installed the kit on an RS7 development vehicle, on our Dynopak hub dyno we saw improved power and torque throughout the rev-range, with consistent gains of +4WHP and +4NM over the stock filter and hoses when used with Revo Stage 1 ECU performance software.  BENEFITS Increased airflow +4 WHP and + 4 NM gain Retains factory airbox Custom designed Silicone Hoses Revo ProPanel filter AIR FILTER The standard paper filter found in most vehicles performs well under normal conditions, however, with increased power it becomes a major choking point in the system. Revo ProPanel 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. We tested the filter at a leading motor testing centre ‘Mira’ on an industry recognised dust load test. On a full dust load test, the foam filter was found to still be 99.3% efficient, filtering down to 5 microns while offering the least amount of restriction over similar products. SILICONE HOSES The plastic hoses on the stock system design 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 turbos. We designed the silicone hoses with stepped internals to ensure a flush fit and to minimise turbulence while still allowing for engine movement.     INTAKE PERFORMANCE FIGURES Engine Software Power Torque 4.0 TFSI Stage 1 + 4 BHP + 4 NM   *Maximum power and torque increases are shown in testing when using Revo 4.0 TFSI intake system compared to the stock intake on Audi RS7   TECHNICAL DOCUMENTS The following documents are available to view: FITTING INSTRUCTIONS Download the  RA731M200200 Revo 4.0 TFSI Air Intake System Fitting Instructions     FITTING      Manufacturer Model Engine Year Audi RS6 4.0 TFSI 2012 > Audi RS7 4.0 TFSI 2012 >

Revo ProPanel FilterHigh-Performance Air Filters OVERVIEW The Revo ProPanel is a high-grade direct replacement filter for your vehicle. Designed as direct replacement filters to fit inside your factory air box and are suitable for road or competition use.   BENEFITS Designed to increase horsepower and rate of acceleration Exceptional filtration High airflow with three layers of foam Lifetime warranty Lasts up to 60,000 miles before cleaning is required depending on driving conditions Works with original manufacturers air box   DESIGN AND PERFORMANCE Why choose foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves optimum performance against three key criteria: Maximum airflow: the ability to allow air to pass through without causing a large drop in pressure. Cleaning efficiency: the capability to arrest a high proportion of airborne dust while feeding the engine clean air. Dust load-up tolerance: the capability to absorb a large amount of dust without reducing airflow capacity. This design of filter has been used in all fields of motorsport from Formula 1 to the World Rally Championship. The range receives this same attention to detail at the design stage and is then taken into production with consummate quality.   THREE LAYER FOAM SYSTEM Revo ProPanel Filters use multi-layered foam technology to trap dust and dirt while maintaining flow efficiency over time. Using foam increases the filter's surface area and is washable, compared to standard paper and cotton filters which trap dust on the surface and become less efficient the more they are used, choking the engine and reducing performance. The outer core is a coarse foam designed to trap larger particles, the second layer is a medium foam designed to trap most particles and the inner core is fine foam which will trap any particles small enough to reach it. The triple layer foam design ensures an exceptional level of engine protection and long-term performance advantage.     1: Stainless steel wire mesh To avoid erosion, only the highest quality steel is used.   2: Course outer layer:  Stops large pieces of dirt and foreign matter from penetrating further. Straightens airflow into subsequent layers.   3: Medium grade middle layer:  This second filtration layer traps most of the harmful dirt that leads to engine damage.   4: Fine inner layer:  Extracts fine particles while allowing full air flow to the engine for maximum power.     ADVANTAGES OF A REVO PROPANEL FILTER Emissions legal in all 50 US states Will not void vehicle warranty Lifetime warranty (to original purchaser with proof of purchase)     FITTING      Manufacturer Model Engine Year Audi RS3  2.5 TFSI  2015 > Audi TTRS  2.5 TFSI  2016 > VW Arteon  2.0 TDI  2017 > VW Passat  2.0 TDI  2014 >
