This is the Grimmspeed OEM Style Intake Manifold Gasket. This particular intake gasket has been made using quality rubber coated embossed metal materials to ensure a proper seal between the intake manifold and the engine block. If you have a vacuum issue or an unusual idle, then your intake manifold gasket could be the culprit. With that being said, save yourself the expense of making a trip to the stealership, and get one on order from RallySport Direct.
