on CED it says 08s have a diff intake manifold and the 2.2 -2.4 kit has not been tested on an 08 yet , does anyone know if it will still fit? i searched and found nothing specific for 08's

 

there is a specific how-to for the 2008 by Maven in the "how-to" section. But if your 07-08 your better off getting the manifold and gaskets from gmparts, because its way cheaper and you don't need the ced adapter plate...
