Before you order: GM part numbers change by option code and year. Confirm against your VIN with a GM dealer. Callout numbers on this page are our own and do not match GM's diagram numbers. Quantities are per vehicle (both sides).
Engine: this page covers the 2.4L 4-cylinder (LAF 2010-2011, LEA 2012-2017) only. For the 3.0L / 3.6L V6, see Manifolds V6. On the 2.4L the exhaust manifold bolts to a separate catalytic converter. Secondary air injection parts (22) are only on engines with option NU6. The drawing is simplified and not to scale.
