Filter Options

The aFe Air Filter is available in two media types to suit different driving preferences and maintenance routines:

• Pro 5R (Oiled): Features five layers of progressively finer oiled cotton gauze media designed for maximum airflow and power gains. Ideal for performance enthusiasts, this filter is washable and reusable, maintaining efficiency even when dirty.
• Pro DRY S (Non-Oiled): Utilizes three layers of synthetic media offering excellent filtration and high flow without the need for oiling. Perfect for daily drivers or those seeking quick, no-mess maintenance. Also washable and reusable.

Construction & Design

The aFe Air Filter is engineered with a durable 100% polyurethane frame that provides long-lasting strength and flexibility. This robust frame maintains a factory-style fit and resists deformation over time. The filter media is pleated in a rounded, evenly spaced pattern to maximize usable surface area, which enhances dust-holding capacity and airflow efficiency.

The progressive bump seal is crafted from soft urethane that conforms to the contours of the factory airbox, ensuring a tight and reliable seal without additional gaskets or sealants. This design feature helps prevent unfiltered air from bypassing the filter, protecting your engine from contaminants.

Installation of the aFe Air Filter is straightforward and requires no modifications. It is a direct drop-in replacement for the factory air filter in Dodge Ram trucks equipped with engines ranging from 3.7L V6 to 8.3L SRT10, covering all models from 2002 through 2012. The filter’s precise fitment ensures a secure seal and optimal performance immediately after installation.
