  Lower Manifold, Manifold Assembly Inlet

• Description:

  This is the genuine Ford lower intake manifold for 4.6L and 5.4L SOHC modular V8 engines without supercharger. It mounts to the cylinder heads and routes intake air and the fuel charge into the ports, sealing the upper manifold and throttle body to the heads while carrying coolant passages and sensor and injector provisions. It fits 1999 to 2007 F-150, F-250, F-350 Super Duty, Excursion, Expedition and E-Series built with the naturally aspirated SOHC modular engine. Owners need this manifold after cracks develop, after coolant or vacuum leaks, or when the original casting is damaged during other repairs. Symptoms of a failing intake include coolant loss with no obvious external leak, rough idle, vacuum leak codes, overheating, and a coolant smell, since the manifold's coolant crossover is a known wear point as the casting and gaskets age. Replacing it with the correct genuine part restores proper sealing of air, fuel and coolant passages. Installation requires new intake gaskets, careful cleaning of the head sealing surfaces, correct bolt torque in the specified sequence, and attention to coolant and vacuum line routing. Confirm engine displacement and that the application is non-supercharged against your VIN before ordering. Genuine Ford casting ensures correct port matching, coolant passage layout, sensor bosses and bolt pattern for a leak-free repair.
