Upgrade from your OEM Air Filter and increase airflow with the aFe MagnumFLOW OER PRO IRF

One of the easiest, quick upgrades you can make to your Ford Mustang is to swap out for OEM air filter for the aFe MagnumFLOW OER PRO Inverted Replacement Filter. Airflow is essential to engine performance, and if you don't have the right air filter for your needs, impurities and dirty air could be running through your machine.

The aFe Inverted Replacement filter is the largest filter you can fit into the OEM airbox on your Mustang. The performance increase is made possible by the integrated urethane bump seals, polyurethane construction, and the inverted positioning. All of these help produce 33% more outflow than your stock air filter. It also helps that the mesh cotton gauze media used gets progressively finer, further helping the direction of airflow. Remember, higher rate of airflow = higher performance. This aFe MagnumFLOW OER PRO filter comes in two versions, the Pro 5 R, which is an oiled filter, and the Pro Dry S, a non-oiled version.
