The aFe MagnumFLOW Pro DRY S Air Filter (21-90108) revolutionizes air filtration with its advanced oil-free synthetic media technology. This universal fit conical filter combines three layers of progressively finer synthetic media to achieve 99.2% filtration efficiency while maintaining exceptional airflow. The 5" flange x 9" height design features a rigid 100% polyurethane frame that withstands repeated cleaning cycles without deformation. Unlike traditional oiled filters, the Pro DRY S media eliminates the mess and maintenance of re-oiling while providing superior protection against contaminants. The tall, open pleat design maximizes surface area for both airflow and dust-holding capacity, extending service intervals. A unique polyurethane flange with integrated bumps creates a perfect seal against the intake housing, preventing unfiltered air from bypassing the media. This filter is particularly suited for modern fuel-injected engines where precise airflow measurement is critical.
