Product Description

The aFe MagnumFLOW Pro-5R Replacement Air Filter (24-91127) is a premium universal performance filter engineered for custom and aftermarket intake systems where a vehicle-specific air filter is not applicable.

With a 4.5" flange and a 9"x7.5" base profile, this universal filter is designed for clamp-on performance intake setups, cold air kits, turbo inlets, and other aftermarket applications. Its heavy-duty polyurethane top and base combined with an integrated bump seal ensure a secure, leak-free fit when clamped. The open pleat design increases usable media surface area, promoting enhanced engine breathing and throttle response. Washable and reusable construction simplifies maintenance and extends service life - ideal for enthusiasts and custom builders seeking improved airflow and durable performance.
