Ease of Use/Installation:
Overall Rating:

The manifold and gasket fit correctly. The ring was not needed for this application. However the heat shield did fit and was not as good construction as the original. Ended up using the original heat shield. The car now runs very quiet and gas milage is back to where it is suppose to be the oxygen sensor was giving wrong readings because the old manifold was completely broken in half thus air getting to the sensor. Very pleased with the manifold.
