NOTE: Lightly oil all retaining bolt and stud bolt threads with Motorcraft Super Premium 5W30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G before installation except those specifying special sealant.

Clean mating gasket surfaces of lower intake manifold and upper intake manifold. After scraping, carefully remove any gasket particles to prevent them from entering lower intake manifold.
