This aFe POWER Pro 5R is a 7-1/2" tall, pre-oiled, 360-degree radial flow performance air filter with five layers of progressively finer cotton gauze media for maximum performance. It provides your engine with the largest amount of high-flowing air, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street and/or track use.

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.

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.

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.
