Filter Options

The aFe Magnum FLOW Pro 5R Air Filter is offered in two media types to suit different driving styles and maintenance preferences:

• Pro 5R (Oiled): Features five layers of progressively finer cotton gauze pre-oiled for maximum airflow and filtration efficiency. Ideal for high-performance applications including spirited street and track use. This media can be cleaned and recharged using aFe’s POWER CLEANER and blue oil.
• Pro DRY S (Non-Oiled): Utilizes three layers of synthetic media that require no oiling, offering low-maintenance convenience. Best suited for daily driving and light off-road conditions. Cleaning involves simply washing with aFe’s POWER CLEANER without the need for oils.

Construction & Design

Built with durability and performance in mind, the aFe Magnum FLOW Pro 5R Air Filter features a 100% polyurethane frame that resists heat and deformation, ensuring structural integrity through repeated engine heat cycles. The deep, open pleat design maximizes surface area, allowing for superior dust holding capacity and consistent airflow.

The progressive bump seal is engineered to create a perfect, leak-free fit by conforming to the contours of the factory airbox. This eliminates the need for additional gaskets or sealants, ensuring that all incoming air passes through the filter media for optimal engine protection.

Installation & Fitment

Designed as a direct OE replacement, this aFe air filter installs easily into the factory airbox of compatible vehicles without any modifications. Its precise fitment ensures a secure seal and optimal performance immediately upon installation. Routine maintenance is straightforward, involving cleaning and re-oiling for the Pro 5R or washing for the Pro DRY S, extending the filter’s service life and maintaining peak airflow.
