Dorman Plastic Intake Manifold - Includes Gaskets

Instructions to install the part are straight forward (included with part). You will spend more time getting to the intake manifold than removing the intake manifold. Your ignition coils and certain accessories that are mounted on top of the manifold (that don't require a torque wrench) are install using self tapping screws (comes included with manifold). Gaskets and coolant crossover tube come pre-installed on the manifold, which makes it nice when installing it. Made sure the mounting surface (on the engine) was well cleaned and have not had any leaks so far with this product. You will need to research the torque on the mounting bolts and throttle assembly that mounts on top(Haynes manual helped me). Good job for someone with a working knowledge of an engine, not good for a first timer.

If you like gambling with you time and money buy this manifold if not stay away! I bought this Intake manifold to replace the factory oem on a 2004 f-250 5.4 that developed a leak on the cross over. After reading the reviews for this unit and watching a few youtube videos online, I was nervous and hesitant on buying this unit. I was hesitant on buying this manifold due to the fact so many people had reported that the manifold had failed right out of the box , costing people tons of time and money. The large amount of negative reviews for this manifold consisted of poor workmanship including Holes or cracks in the plastic along with injector rail holes not drilled out causing the manifold to fail out of the box. After calling around to a few junk yards and finding out the price oem from ford dealer I decided to take a chance and save a few bucks and bought this unit. I figured what are the odds, and not every manifold could be bad so I took a chance and off To Advance I went. Man was I wrong! When I got home home I opened the box to inspect the manifold and I immediately noticed three small holes/chips in the plastic making the part defective. Also on the crossover rail I noticed what looked like a small crack that was filled in with a epoxy. I brought the part back to the store to exchange and manger agreed that part was defective and went in the back to get another. When we opened up the second unit we also discovered even more holes and chips in the plastic. The store employee deemed both units were defective and gave me a full refund. wow two identical manifolds with that same holes and chips. No quality control! See attached pictures.....good luck!
