Upgrade your Focus ST with this high-performance silicone inlet hose, designed to improve airflow and boost engine response.
By replacing the restrictive factory hose, it provides a smoother, more efficient air path to the turbo, resulting in improved throttle response and proven power gains of around 5–7bhp (vehicle dependent).
Made from durable black silicone for a clean, OEM+ look, this inlet hose is a simple yet effective upgrade for both standard and tuned cars, helping your Focus ST breathe better and perform at its best.
