The Saleen Supershaker takes the already fantastic Saleen Series IV supercharger to the next level of performance and style. A shaker hood scoop system is added on top of the supercharger to provide a direct cold air inlet and that means more power! Of course the shaker scoop looks great on the 05-09 Mustang! This kit is complete with supercharger system, intercooler, injectors, colder plugs and of course the supershaker intake.
