OEM+ Air Intake System Ford Focus ST MK4/MK4.5 2.3 EcoBoost

The Revo OEM+ Air Intake System is engineered to enhance the performance of the Ford Focus ST MK4/MK4.5 2.3 EcoBoost without altering the factory engine bay appearance. The original intake on the Ford Focus ST MK4 was identified as a significant restriction, hindering the vehicle's performance potential. The Revo OEM+ Air Intake System addresses this by incorporating a Revo Pro Panel Filter, which uses oiled foam layers to trap dirt while allowing unrestricted airflow, offering longer service intervals compared to standard paper filters. Two flush-fit silicone hoses are included to reduce restriction and turbulence, while still accommodating engine movement. The system also features an alloy hard pipe with an increased bore size and OE-style machined fittings for breather and DV connections, ensuring perfect OEM fitment and providing ample flow for various tuning stages.
