aFe MagnumFLOW Pro DRY S Universal Air Filter 4" Flange x 6" Base x 4" Inverted Top x 8" Height 21-91155
$91.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The aFe MagnumFLOW Pro DRY S Universal Air Filter (21-91155) provides high-efficiency filtration with maximum convenience for street and light off-road use. This performance filter features three layers of oil-free synthetic media, eliminating the need for oiling during maintenance cycles. Its progressive layering is designed to maximize dust-holding capacity while maintaining superior airflow.
Built for durability and ease of use, the filter is constructed with 100% polyurethane on both the base and the top, ensuring excellent strength and resistance to heat and chemicals. The rounded, evenly spaced pleat design increases the total filter surface area, while the inverted top further expands that area to allow for longer service intervals. This filter utilizes a molded-in retention groove, allowing it to lock securely into most aFe Stage-2 intake housings without the need for additional hardware.
