Key Features:

Built to outperform stock paper filters, the aFe Magnum Flow air filter offers several key advantages:

• Outflows stock paper filters by up to 14% for improved horsepower and torque
• Constructed with 100% polyurethane frame on all sides for enhanced durability and long filter life
• Pro DRY S media uses three layers of progressively finer cotton gauze mesh for maximum airflow and filtration efficiency
• Washable and reusable design supports multiple cleaning cycles, reducing replacement frequency
• Integrated urethane bump seal ensures a tight, leak-free fit throughout the filter’s lifespan
• Tall, open, evenly spaced pleats provide excellent dust holding capacity for longer service intervals
• Oil-free design eliminates mess and simplifies maintenance

Construction & Design:

The Magnum Flow air filter features a robust 100% polyurethane frame that resists cracking, warping, and degradation over time, even under harsh engine bay conditions. The Pro DRY S media is composed of three layers of cotton gauze mesh, each progressively finer to trap contaminants while allowing unrestricted airflow. This inverted design maximizes the filter surface area, promoting better engine breathing and efficiency.

The urethane bump seal is precision molded to create a secure, airtight fit, preventing unfiltered air from bypassing the filter element. The pleated media design increases the filter’s surface area, enhancing dust capacity and extending the interval between cleanings.

Performance & Sound

By increasing airflow by up to 14% compared to stock paper filters, the aFe Magnum Flow air filter helps improve engine responsiveness, horsepower, and torque. This enhanced breathing capability supports better combustion efficiency, which can translate into smoother throttle response and potential fuel economy benefits. The oil-free design also ensures consistent performance without the risk of over-oiling or filter damage.

Installation & Fitment:

Installation is straightforward and requires no modifications. This air filter is designed as a direct replacement for the factory air filter in Dodge Ram 2500 and Ram 3500 trucks from 2003 through 2010. Simply remove the old filter and install the Magnum Flow filter in the airbox, ensuring the urethane bump seal seats properly for a leak-free fit. Routine maintenance involves washing and reusing the filter media, making upkeep simple and cost-effective.
