Finish: silver
Stated fitment: 2005 to 2010 Chevrolet Cobalt, 2006 to 2010 Chevrolet HHR, 2004 to 2005 Saturn Ion-1, 2004 to 2007 Saturn Ion-2, with the 2.2L or 2.4L I4 non-turbo engines only; not the Cobalt 2.0L supercharged
Check the listing details for gaskets and fixings, and compare the flange pattern and the downpipe connection with your own manifold before ordering.
Practical tip: fit a new gasket, use anti-seize on the studs, torque from the centre outwards and re-check after the first few heat cycles.
