The Roush cold air intake for 2005–2009 Mustang with the 4.0L V6 includes a ROUSH synthetic nano-fiber filter, air dam and modular intake tube (MIT) to improve airflow. The filter media traps finer particulates than typical cotton-gauze filters, is washable and reusable and carries a lifetime warranty. The MIT, made from cross-linked, high-density polyethylene, can improve airflow up to 400 CFM and the kit installs without cutting or drilling.
