Construction & Design

The Magnum FLOW Pro Dry S air filter features a robust 100% polyurethane frame that resists cracking and deformation, ensuring a consistent and secure seal over time. Its filter media consists of three layers of synthetic mesh arranged from coarse to fine, allowing for high airflow rates while effectively trapping contaminants. This progressive layering maintains airflow even as the filter collects dirt, extending service intervals.

The rounded pleat design maximizes surface area, enhancing filtration efficiency and dust holding capacity. The urethane bump seal flexes to fit perfectly within the airbox, preventing leaks without compressing or damaging the seal. This thoughtful engineering eliminates the need for additional sealing materials, making installation and maintenance easier.

By significantly improving airflow compared to stock paper filters, the aFe Magnum FLOW Pro Dry S air filter supports enhanced engine breathing, which can lead to improved throttle response, horsepower, and torque. Its consistent performance under demanding conditions makes it suitable for both everyday driving and spirited use. While primarily focused on filtration and flow, the improved air intake efficiency may also contribute to a subtle enhancement in engine sound, delivering a more engaging driving experience.
