This listing is for one 1999 Ford Mustang Cobra 4.6L Vortech V-2 Polished Supercharger Kit. This kit was pulled off of a 1999 Cobra with 21,048 miles. This is a clean kit, and comes with more parts than when you purchase it new. Such as the injectors, and fuel pump. Including the coolant crossover as well. The ECU is included, but will probably just use yours, and have it tuned. This is a new used complete kit. Oil pan is already threaded with the fitting, and hoses are attached to the head unit. Including a boost gauge also. See above photos. Any questions please feel free to ask. We look forward to your business.
