The aFe MagnumFLOW Pro DRY S Air Filter (21-50505) combines compact dimensions with high-flow performance in a durable oil-free package. Measuring 5" flange x 5" height, this filter utilizes three layers of progressively finer synthetic media to achieve 99.2% filtration efficiency - among the highest in its class. The 100% polyurethane construction ensures long-term durability, resisting the heat and vibration encountered in engine compartments. Unlike traditional oiled filters, the Pro DRY S media eliminates the hassle of re-oiling while maintaining excellent airflow characteristics. The integrated bump seal creates a positive seal against the intake housing, preventing contaminant bypass. Designed for easy maintenance, this filter cleans easily with soap and water and dries quickly for rapid reinstallation. The compact dimensions (5"F x 6.5"B x 4.75"T x 5"H) make it ideal for applications with limited space, while the tall pleat design ensures adequate surface area for both performance and longevity. Perfect for modern fuel-injected engines where precise airflow measurement is critical to optimal performance.
