2005-8 SHAKER SYSTEM is now available. This Ram Air/Cold Air Package includes all the duct work to make it fully functional. The Shaker System includes an Engine dress up cover, Cast Aluminum Scoop and all the necessary hardware, instructions and templates. In addition CDC has engineered water management systems within the shaker ductwork. The CDC Shaker System uses the factory air box so Engine flashing is not necessary. The CDC Shaker System also comes standard with a High Flow/High Performance S&B Filter. The Shaker System will use your factory hood which has a factory stamping in the hood inner, which accommodates the shaker system installation process, while maintaining the integrity of the hood. We will post updates as they are available. PLEASE NOTE: CDC'S TRIM RING DOES NOT COVER THE FACTORY HOOD SCOOP HOLES (07 FACTORY HOOD SCOOP)
