You can Select Your Vehicle to check if 17150-0P330 fits your vehicle.

Before lifting the exhaust manifold, the first thing that should be done is to disconnect the cable of the battery's negative terminal. Lift the front of the vehicle and set it on jackstands safely and then, take off the lower splash shields and front floor cover from the left side. Pry these bolts loose while being very careful not to remove the oxygen sensors by applying penetrating oil on the bolts that hold the exhaust pipe to the manifold and allowing them to soak before removal. Unfasten the exhaust neck from the manifold, undo the down exhaust manifold girders, and unsnap the connectors on the oxygen sensor. Situated in the engine compartment, it is necessary to take off only the upper heat shield from the manifold while observing that the last type of heat shield is not required to be detached. Remove the nuts/bolts and take off the manifold along with its gasket. For installation you will use a scraper to scrape the mating surface of the manifold and cylinder head cleaning it and during this process you will check for warpage if the gasket is in bad state and it is leaking. If changing a manifold only, bolt the lower heat shield onto the new one. Place a new gasket over the studs on the cylinder head and ensure the manifold is fitted Thread the mounting nuts starting with the middle one before you tighten all of them. Replace the rest of the parts in the reverse order you removed them, starting the engine to check for leakages through the exhaust.

Tighten the exhaust manifold nuts a little at a time, working from the center nuts outward, to the specified torque.

Run the engine and check for exhaust leaks.

Replacement procedures vary based on model year and engine type. Always ensure the catalytic converter has cooled before servicing to avoid injury.
