Construction & Design:

The Magnum FLOW air filter features a robust 100% polyurethane frame that provides excellent structural integrity and resists degradation over time. This full 360-degree urethane frame ensures a precise OE-style fit, maintaining a secure seal and preventing unfiltered air from entering the engine.

Its advanced three-layer Pro Dry S media employs progressively finer mesh layers to trap contaminants effectively while allowing high airflow. The tall, evenly spaced pleats maximize surface area, enhancing dust holding capacity and extending service intervals between cleanings. The urethane bump seal is engineered to maintain its shape and sealing ability, ensuring consistent performance without compression or leaks.

This improved airflow supports more efficient combustion and throttle response. Additionally, the filter’s design maintains optimal filtration without restricting intake sound, preserving the natural engine tone.
