Show original supplier description

The GM 12587878 is a genuine GM Original Equipment Engine Intake Manifold Assembly designed to evenly distribute the incoming engine air to each of the cylinders, ensuring the proper amount of air for optimal performance. This direct replacement part is new and comes with GM's factory warranty, offering a minimum of 12 months of coverage. This intake manifold is specifically designed for 2006-2007 Chevrolet Cobalt, Chevrolet HHR, Pontiac G5, Pontiac Pursuit, Pontiac Solstice, Saturn Ion, and Saturn Sky models equipped with the 2.4L engine. It is crucial to select the correct vehicle in your garage or consult detailed fitment information to ensure compatibility with specific body styles and trim levels. Installation involves several steps, including disconnecting the negative battery terminal, removing components that may interfere with access (such as turbochargers or air filter housings), and removing the intake manifold cover, throttle body, and fuel rail. It is recommended to use a new gasket when reinstalling the intake manifold and to ensure clean mating surfaces between the manifold and cylinder head. For detailed installation instructions, refer to vehicle-specific service manuals or consult with a professional technician.
