Its open design allows for easy viewing of the air filter, yet creates a heat-blocking seal when the vehicle's hood is closed. It™s design incorporates the OEM air scoop to ensure that it gets the coldest air available.Hassle-Free Installation: This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps, couplings, and hardware are included. Its revolutionary design, featuring our unique filter-to-housing interface, uses half the number of parts of a traditional cold air intake system.
