AFE designed the Pro 5R for the performance customer in mind. High density airflow is the name of the game when aiming for more power. This doesn't mean you must sacrifice the safety of your engine either. Five progressively more tight medical cotton layers protect your engine with a proven 98% efficiency. The Pro 5R is the only material in this class that progressively tightens the weave of its material.

While some filter material compromises between airflow and effectiveness the Pro 5R does not. You get maximum airflow for performance and the peace of mind no debris can ruin the day.
