The aFe MagnumFLOW Pro DRY S Air Filter (21-91155) delivers high-performance filtration through its three-layer oil-free synthetic media. Measuring 4" flange x 8" height in an inverted design, this filter provides maximum surface area for improved airflow and extended service intervals. The polyurethane construction ensures proper fitment while the retention groove allows tool-free installation in most Stage-2 housings. Unlike oiled filters, the Pro DRY S media cleans easily with aFe POWER CLEANER and requires no re-oiling. The rounded, evenly spaced pleat design increases usable filter area by 25% compared to conventional filters, while maintaining 98% filtration efficiency. Ideal for street and light off-road applications.
