This aFe POWER Pro DRY S is a 7-1/2” tall, oil-free, 360-degree conical flow performance air filter with three layers of synthetic media for maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street and light off-road use. This system features a two-piece, computer-designed, roto-molded intake tube to achieve maximum power gains while maintaining a perfect fit. Constructed from XLPE (cross-linked polyethylene) polymer, it is heat soak resistant and extremely durable. A factory-style Helmholtz Chamber is integrated into its design, toning down any drone. The sealed XLPE polymer housing features a rugged design, as well as a clear sight window, allowing for hassle-free filter inspection. aFe POWER's patent pending filter-to-housing interface eliminates the use of an overabundance of parts, further simplifying the installation process. The housing utilizes the factory air inlet, using no additional hardware, and features an optional auxiliary air inlet that pulls in additional air. All stainless-steel clamps, hardware, and silicone couplings are included for a hassle-free installation. This is a direct bolt-on kit that requires no cutting or drilling on OEM parts.
