This listing is for one 2004 Ford Mustang GT 4.6L Kenne Bell Supercharger Kit. This kit was pulled off of a 2004 Mustang GT with 48,161 miles. This is a clean kit, and comes with more parts than when you purchase it new. Fits the 2001-2004 4.6L GT’s according to Kenne Bell. Will have to have your Mustang tuned after install. See above photos. Any questions please feel free to ask. We look forward to your business.
