Description
The aFe Magnum FLOW Pro 5R Air Filter (afe30-10307) is a high-performance OE replacement air filter designed specifically for the Ford Fiesta and Fiesta ST, delivering up to a 71% increase in airflow over the stock paper filter. Engineered for both daily driving and aggressive street or track use, this filter improves horsepower, torque, and throttle response while maintaining excellent filtration efficiency.
This filter uses aFe’s Pro 5R factory-oiled, five-layer cotton gauze media, constructed with progressively finer mesh to maximize airflow even as the filter loads with debris. The deep, rounded open pleats significantly increase usable surface area, enhancing airflow and dust-holding capacity for longer service intervals.
A full 360-degree polyurethane frame combined with a progressive urethane bump seal ensures a precise OE-style fit with a tight, leak-free seal—no gaskets or sealants required. Fully washable and reusable, the Pro 5R air filter offers long-term performance, durability, and value.

Filter Media & Construction
The Pro 5R filter media features five layers of pre-oiled cotton gauze, designed with progressive layering to maintain high airflow even when dirty. This makes it ideal for street and track-driven vehicles. The rounded, evenly spaced pleats increase dust-holding capacity, while the soft urethane bump seal conforms to uneven airbox surfaces and always returns to its original shape, ensuring a consistent seal throughout the life of the filter.
The full polyurethane frame resists heat-cycle degradation and maintains its molded shape, unlike cheaper rubber or plastic alternatives.
