Revo OEM+ Air Intake System

FORD FOCUS ST MK4/MK4.5 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

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.

Silicone hoses

The plastic hoses on the stock system have a corrugated style design 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 hoses with stepped internals to ensure a flush fit, and to minimise turbulence while still allowing for engine movement.

Alloy Hard Pipe

The OE hard pipe section on the intake does its job as standard but when power is required it becomes a choking point. The Revo hard pipe has an increased bore size to match with the stepped silicone hoses providing ample flow for various stages of tuning. The hard pipe also has OE style machined fittings for both the breather and DV connections allowing complete OE fitment.
