Product Description

The aFe MagnumFLOW UCO P5R Air Filter (24-91009) is a universal performance air filter designed for custom intake systems, turbo inlets, and aftermarket kits where vehicle-specific filters are not applicable. Featuring oiled, multi-layer P5R cotton gauze media, this filter delivers high airflow combined with effective debris capture and engine protection, outperforming standard paper filters in both flow and filtration.

With a 4" flange, 8" base, inverted 7" taper, and 8" overall height, this filter's geometry is optimized for universal clamp-on configurations. The inverted design enhances fit versatility and airflow direction, while the open pleat and heavy-duty polyurethane construction increase usable media surface area and durability under demanding conditions. Built for reusable service, this filter can be washed, re-oiled, and reused for extended life - ideal for performance enthusiasts and custom builders seeking enhanced airflow, protection, and simplified maintenance in their intake setups.
