Pro DRY S filters are easily recharged with aFe's POWER CLEANER. aFe developed this sturdy 18 gauge steel wrinkle-black powder-coated heat shield to snap onto the top of the lower half of the factory airbox to provide a hassle-free installation utilizing factory mounting locations. The retention groove on the filter base locks the filter onto the heat shield without any additional hardware. This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit.
