The Foust Edition COBB Intake for the Focus ST takes a great airbox design and makes it even better! We improved upon the factory airbox ram air ducting by including an oiled dual cone filter to increase airflow and to hear that great turbo sound. The constrained piping to the turbo is replaced with 3" mandrel bent aluminum tubing to maximize air flow while custom silicone couplers ensure a perfect OEM-like fitment. You can also proudly display your fine taste in performance modifications with a Foust Edition graphic for the intake tubing. The Foust Edition COBB Intake is the perfect first step towards Stage 2 power levels when paired with the Foust Edition COBB FMIC!
