The aFe MagnumSHIELD pre-filter in yellow slips over compatible performance air filters to stop large debris and extend time between cleanings. Its dry weave fabric resists dirt attraction, rinses clean with soap and water, and is claimed not to restrict airflow. The guard protects the underlying filter while adding a splash of color to the intake and prolonging service intervals.
