Key Features

The aFe Magnum FLOW Pro DRY S Air Filter incorporates several innovative features that set it apart from standard OEM filters:

• 100% polyurethane frame on all four sides for a robust, OE-style fit and superior durability
• Pro DRY S three-layer synthetic media providing progressive filtration for maximum airflow even when dirty
• Oil-free design eliminates the need for messy oiling during cleaning, enhancing convenience
• Rounded open pleats increase usable filter surface area, improving airflow and dust holding capacity
• Integrated urethane bump seal ensures a tight, no-leak fit that conforms to uneven filter housings
• Washable and reusable construction supports multiple cleaning cycles, extending filter life
• Tall, evenly spaced pleats optimize dust loading and maintain airflow for longer service intervals

Construction & Design

The filter’s full 360-degree urethane housing provides exceptional strength and a precise OE-style fit, ensuring it seats securely within the airbox. The synthetic media is engineered with two layers of progressively finer mesh that trap contaminants effectively while allowing high airflow rates. This progressive layering technology enables the filter to maintain performance even as it accumulates dust and debris.

The pliable urethane bump seal is designed to compress and rebound, creating a reliable seal without the need for additional gaskets or sealants. This design feature guarantees a leak-free installation and consistent filtration performance throughout the filter’s service life.

Performance & Sound

By replacing the restrictive stock paper filter with the aFe Magnum FLOW Pro DRY S, drivers can expect improved engine breathing that translates into enhanced throttle response, increased horsepower, and better torque delivery. The high-flow design supports more efficient combustion, contributing to overall engine efficiency without altering the factory sound profile.

Installation & Fitment

Installation is straightforward and requires no modifications to the vehicle. The filter is designed as a direct OE replacement for the 2002–2004 Jeep Grand Cherokee 4.7L V8, ensuring a perfect fit and seamless integration with the existing air intake system. Simply remove the factory air filter and replace it with the aFe Magnum FLOW Pro DRY S for immediate performance benefits.
