This intake manifold features a Dorman-patented consolidated port
design (Patent #USD700621S1). This manifold will function for vehicles
using both square and round ports.
INSTALLATION SPECIFICATIONS
• This updated manifold does not require additional intake gaskets.
The intake gaskets are already installed into the manifold.
• Be sure to fully seat the injectors when installing the fuel rail.
Failure to do so will result in a vacuum leak.
• To install fuel rail, the M6 self-tapping fasteners are tightened by
angle and then by torque. First, start the fastener 1080° (three
turns), then tighten to 44-61 in-lb (5-7 Nm). You may find that
proper torque has been reached or exceeded within initial three
turns. This is acceptable and torque does not need to be lowered
if this occurs. Not all self-tapping screws are used for every
application. DO NOT OVERTIGHTEN!
• To attach ignition coils, use provided M5 self-tapping screws.
Tighten down 27 in-lb (3 Nm). NOTE: Initial turns
are not necessary for the M5 self-tapping screws.
DO NOT OVERTIGHTEN!
• The 4.6L engine was built at 2 different Ford plants (Romeo and
Windsor). There were several cylinder head designs produced at
these locations. We have found that sometimes the original OEM
gasket alignment holes in the head were placed a position near or
under our gasket's centerline location. If you find this is the case,
simply fill these holes with high-temperature RTV silicone prior to
manifold assembly to avoid a vacuum leak.
