Show original supplier description
The Ramair SR-225-BK-ECU is a performance induction kit specifically designed to replace the restrictive OEM air box in the Ford Focus ST 225 MK2. By upgrading the factory intake system with this high-flow component, the engine can breathe more freely, leading to improved throttle response and a more satisfying induction sound. Ramair guarantees an increase in power and throttle response by replacing restrictive OEM intake systems. Key features of this kit include a Ramair MAF safe dry foam filter with a substantial 1032cm2 surface area, ensuring high filtration levels critical for engine longevity. A standout component is the CAD-developed, laser-cut aluminum ECU bracket, finished in a satin black powder coat. This bracket mounts to the standard fixing points, meaning there is no need to modify your engine bay or relocate the ECU. The kit includes a twin-layer foam filter, black silicone elbow and coupler, the aforementioned ECU bracket, a full fitting kit with all necessary hardware, and detailed fitting instructions. The product is available with a choice of silicone hose colors: black, blue, red, or orange. Ramair's foam filters are known for producing a clean, progressive intake roar that builds with engine speed. Important: This kit replaces both the standard airbox and the standard ECU bracket. The replacement bracket fits to all factory mounting points, but please ensure you are comfortable with this process before fitting, or have the kit installed by a competent mechanic familiar with the Focus ST engine bay.
