Product Description

The aFe 24-91021 Magnum FLOW Pro 5R Universal Air Filter is a high-flow performance air filter element engineered to significantly improve airflow and filtration efficiency in compatible aftermarket intake systems featuring a ~6" inlet flange. Built with five layers of premium pre-oiled cotton gauze media, this Pro 5R filter offers excellent dust holding capacity while allowing substantial airflow potential - helping support improved engine breathing, throttle response, and potential horsepower and torque gains compared with restrictive stock paper filters.

Constructed with a pliable polyurethane flange featuring an integrated bump seal and a rugged 100 % polyurethane top and base, the 24-91021 forms a secure, leak-free fit when clamped into compatible intake openings. Its tall, open pleat design increases usable surface area for enhanced dust holding capacity and extended service intervals between cleanings. Because this filter is a universal-fit element rather than vehicle-specific, always verify that the filter's flange size and overall dimensions match your intake system before installation to ensure proper fit and performance.
