        aFe manufactures numerous sizes of Universal Round Racing air filters for many applications. They feature pleats that are evenly spaced for greater dust holding capacity and tips that are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structures are made from 100% polyurethane, to withstand extreme engine temperatures. The pliable flange with integrated bumps ensures a tight, no-leak seal. Some filters are available with expanded metal that is molded into the urethane, for added rigidity and strength. Universal Round Racing air filters are available with 3 different types of filter media.

        The Pro 5R filter media was designed to provide the maximum airflow possible, to enable your engine to make the most horsepower and torque. But aFe didn't achieve this by ignoring engine protection. The Pro 5R outperforms most other cotton gauze air filters with a 98.6% efficiency rating. The increased airflow and high filtration capability are the result of the Pro 5R's construction. It's made of 5 layers of progressively finer medical-grade cotton gauze.

        The Pro GUARD 7 filter media delivers increased airflow while providing the highest level of filtration efficiency available – 99.7%. The patented 7-layer progressive cotton/synthetic media in the Pro GUARD 7 consists of 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity.

        Competitors use constant size mesh gauze in their filters, which creates voids/openings that can allow dirt to pass through. As the progressively finer layers of gauze are stacked in the Pro 5R and Pro GUARD 7, the randomness of the openings increase, minimizing spaces with no filter media. Dust accumulates on multiple layers, increasing overall dust holding capacity and filtration efficiency.

        The Pro DRY S filter media combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 2 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.
