The primary function of the intake manifold is to distribute the inlet air or air / fuel mixture to each of the cylinders evenly so that the engine can run properly and the vehicle can move.

The only other caution I have is just be careful putting the manifold back on. It is damp in Washington so I did do the RTV around my knock snesors. I just got them from the dealer after that for like 30 dollars more. Don't bother with garabage aftermakret ones.I did and had to go back in. Just pull the fuel rail and injectors as a unit and move them to the side, it will give you enough room. Becareful as the oil pressure sending unit is at the back of the block on the top and if you are not careful you can break it when removing the intake.
