Description

Revo OEM+ Air Intake System


FORD FOCUS ST MK4 2.3 EcoBoost

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 Ford Focus ST MK4 intake has its own unique intake on this platform. The OE intake was a clear choking point in the vehicle’s performance from the outset, highlighting an area in need of improvement. This air intake system upgrade includes a Revo Pro Panel Filter, two flush-fit silicone hoses to minimise air restriction and turbulence and an alloy hard pipe with all OE connections for perfect OEM fitment. Increased bore sizing and smoother transitions improve airflow giving you access to more power.


Key Features

  • Increased airflow speed
  • Increased performance
  • Three-layer foam filter
  • Flush fit silicone hose
  • Alloy hard pipe with OE connectors

Fitting Instructions

Silicone Hoses

No detail has been overlooked when reducing restrictions within the stock airflow system. The stock corrugated plastic hose is replaced with a smooth silicone one, reducing air turbulence and increasing air volume and speed. A four-ply construction with an internal wire helix increases strength to prevent collapsing under pressure. Internal steps flush fit against the hard pipe section and turbo inlet, creating a smooth transition between components and ensuring the smoothest airflow.

Turbocharger Inlet Hose

The integrated sound suppression chamber of the OEM pipe has been removed, allowing for significantly more laminar airflow. The Revo inlet hose geometry allows faster air delivery to the turbo by smoothing the harsh 90° transition part of the stock pipe. Also removing the internal steps between components further ensures uninterrupted airflow and removes any unnecessary turbulence.

Alloy Hard Pipe

The Revo mid-section hard pipe offers a smoother internal geometry over the stock part it replaces, all contributing to the increased performance benefits of the Revo Intake. The pipe has been designed to match the same mounting and vacuum take-off points, ensuring a direct fitment product.

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 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.

Research and Development

All Revo products are designed in-house and are rigorously tested utilising an in-house 3D printer, latest CAD and CFD programs, hub dyno and Revo data acquisition software. The Revo Intake allows the turbo to run more efficiently, intake a larger volume of air and minimise turbulence to increase both power and torque, as highlighted during controlled dyno testing.

The Revo Ford Focus ST MK4 OEM+ Air Intake System was tested in-house to compare the performance against that of the Ford OEM Intake. First tested on a vehicle running the OEM intake with Revo Stage 2 Software, and full OEM hardware, the Revo Intake was then installed and tested in the same controlled environment to highlight the benefits of enhanced airflow.

Performance Data

The results show improvements in power and torque from just 2600RPM, but especially in the peak power. The Revo intake offering an average gain of 18WHP, and +31NM torque over the stock part. Increased airflow also delivers impressive peak performance gains of +42WHP @5100rpm and +69NM @3700RPM over the stock intake system.
