The COBB Focus ST Intake incorporates the great OEM 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 and uses custom silicone couplers to fasten everything together. This is the next generation Focus ST Intake which features OEM-like fitment across all model years and an updated wrinkle black powdercoat finish. The COBB Focus ST Intake is the perfect first step towards Stage 2 power levels when paired with the COBB FMIC!
