Focus RS Intake
The Focus RS is a well-rounded car in just about every aspect, and the Focus RS Intake system is too. The community can see the solid design of the stock intake. Still cp-e™ felt that they could take the good & the bad from the stock system, and make it even better. After a long engineering process, cp-e™ is proud to release the αIntake for the Focus RS. Available powder coated in Satin Black the αIntake offers the most well thought out solution to getting air to your turbo yet. The αIntake comes with a full 3.00” mandrel bent tube. Welded onto the tube are a CNC-lathed port for the PCV system, a CNC-milled MAP bung, and a laser cut support bracket. Includes clear plexi-glass window (ships with orange peel-off protective coating). 
The Focus RS Intake tube then attaches to the air box through a 5-ply silicone elbow and a CNC-lathed aluminum bellmouth. This velocity stack bellmouth smoothly compresses the air from 4.00” to 3.00” providing a minimal amount of energy loss which translates to a higher air speed through the tube. The included 4.00” air filter is specially designed by cp-e™ to give the most free flowing air flow possible. In addition, this is available with your choice between Dflow™ or SynOil™.
Focus RS Intake Construction
Part of what makes the stock intake system well-rounded is the great design of the stock box. It brings in cool air efficiently, and isolates the filter from the hot air in the engine bay. Where the stock box lacks is where the cp-e™ αIntake shines above all. The αIntake box is laser cut and CNC-bent 18 gauge stainless steel. Stainless steel is great for this application for not only its resistance to corrosion, but also its thermal properties allow the interior of the box to stay cool, even when the box itself heats up. The box utilizes both stock fresh air ducts, and also sucks up cool fresh air from the wheel well. A clear Plexiglas tops off the design of the intake. In addition to a sweet view, this gives easy access to the filter. Lastly, the box easily mounts in the stock location with the laser cut brackets and CNC-lathed mounting feet. For a filter replacement, please use our Replacement 4″ Air Filter. Although they may look similar, the Focus ST intake is not interchangeable with the RS intake.
