Engine Intake Manifold

The original equipment intake manifold on certain Ford F-150 trucks with 5.0 liter Coyote engines tends to fail prematurely, particularly when the vehicle is regularly subjected to road salt and other harsh conditions. The resulting rough idle, backfiring and overheating accompanied by a check engine light can quickly lead to an expensive repair. The cause of the original equipment design's failure is corrosion of the manifold's exposed carbon steel rods that operate the charge motion control valve (CMCV, more commonly called IMRC) that can seize or rust to the point of a rod end actually shearing off, disabling manifold air flaps and position sensors. The dealer solution is costly and requires purchasing an entire new manifold and the related components, and many other aftermarket solutions simply mirror the OEM design and invite similar future failures. This new OE FIX manifold features upgraded, stainless steel CMCV shafts that are more corrosion-resistant to provide a more permanent repair than the dealer solution. The improved design also saves installation costs by allowing functional components including the MAP sensor, actuators and fuel hoses to be swapped from the old manifold. For a complete and professional repair, this manifold includes O-rings for the MAP sensor, fuel injectors, PCV outlet, an EVAP purge valve, pre-installed mounting bolts and self-tapping screws.
