Install the right ignition coil. Refer to Ignition Coil Replacement - Bank 1 in Engine Controls-2.6L and 3.2L.

Install the intake manifold. Refer to Intake Manifold Replacement .

It is located under a cap on the drivers side of the engine behind the exhaust manifold. Use a 32 mm (1 1/4 in) socket on the hex on the top of the oil filter cap, or an oil filter wrench on the outside diameter of the oil filter cap to remove. Do NOT use pliers or a wrench as damage will result.

The filter is a cartrige type. it is actually under/ beside the intake on the front of the motor on the drivers side mounted to the block. has a black cap that its best to use the special socket made for the ecotec engine oil filter cap. it is shorter giving you the proper clearance to remove the filter cap without jamming the socket against the intake.
