The Focus RS is a well-rounded car in just about every aspect, and the intake system is too. The stock intake system is designed well, and the community sees that. 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 aIntake for the Focus RS.
Available powder coated in Satin Black the aIntake offers the most well thought out solution to getting air to your turbo yet. The aIntake 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, with your choice between Dflow™ or SynOil™.
Part of what makes the 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™ aIntake shines above all. The aIntake 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. The box is topped off by clear plexi glass to seal the filter from the heat, providing a sweet view and easy access to the filter. Lastly, the box easily mounts in the stock location with the laser cut brackets and CNC-lathed mounting feet.
