This Mustang Cold Air Intake Kit from ROUSH fits 2005-2009 models with the 4.0L V6 Engine, and features the ROUSH air filter, air dam and induction tube. The ROUSH air filter media is a synthetic nano-fiber material that traps the smallest dirt particles that ordinary cotton-gauze performance filters canisters capture. Based on SAE standards, ROUSH air filters capture almost twice the percentage of 2 micron particulates, and more than six times the amount of 0.5 micron particulates than our competitors filters. .This ROUSH air filter is 100% washable, reusable and features a lifetime warranty. Once air passed through the filter, it is taken to the engine through a Modular Intake Tube (MIT) that can improve airflow up to 400 CFM over the restrictive stock intake tube. Made from cross-linked, high-density polyethylene, the MIT straightens out air flow by providing a smooth, unrestricted path that increases air flow to the engine.
