Construction & Design

The filter frame and sealing surfaces are crafted from 100% polyurethane, offering exceptional durability and flexibility. This material ensures the urethane bump seal conforms perfectly to uneven filter housings, maintaining a leak-free seal throughout the filter’s service life. The Pro-GUARD 7 media combines five layers of premium cotton gauze with two layers of synthetic mesh, arranged progressively to trap contaminants efficiently while sustaining high airflow levels even as the filter accumulates dirt.

The rounded pleat design maximizes filter surface area, allowing for greater dust capacity and longer intervals between cleanings. This thoughtful engineering results in a robust, long-lasting air filter that supports your truck’s performance under demanding conditions.

Performance & Sound

By increasing airflow by up to 37% over the stock filter, the aFe Magnum Flow Inverted Air Filter helps unlock additional horsepower and torque, contributing to improved throttle response and engine efficiency. The enhanced breathing capability can also support better fuel economy and smoother power delivery. While primarily focused on filtration and flow, the filter’s design may subtly enhance intake sound, providing a more aggressive engine note without excessive noise.

Installation & Fitment

This air filter is designed as a direct OE replacement for Dodge Ram 2500 and 3500 trucks from 1994 through 2002. Installation is straightforward and requires no modifications—simply remove the old filter and install the aFe Magnum Flow filter in its place. The integrated urethane bump seal ensures a secure, leak-free fit every time, maintaining factory-level sealing integrity.
