Nitrous Express Ford 4.6L 2 Valve Plate System - Manual

Ford 4.6 Liter 2 Valve Plate System Supplemental Instructions
These are your Ford 4.6 Liter 2 Valve Plate System supplemental instructions. In order for proper
installation please follow pages 1-8 of your standard NX installation manual yet disregard the section on
NOZZLE MOUNTING. Be sure to follow these instructions step by step to insure a proper installation.
First, lay all the pieces out to be sure everything
you need is at hand. Take a close look at your 4.6
intake manifold taking notes of wiring connections,
vacuum fitting locations, and throttle cable hook-
ups. Begin by removing all wiring, hoses and cables
connected to the aluminum upper intake manifold.
Now remove the 5 bolts holding the upper intake
manifold (aluminum 90 degree elbow). Set the
upper intake to the side.
Using the original o-ring or gasket place the nitrous
plate on the lower intake manifold. You must be able
to read “TOP” on the top of the nitrous plate and
the word “FUEL” must be facing to the front of the
vehicle.
Although no gasket is needed on the underside of the
plate, the supplied gasket will be needed between the
upper plenum and the nitrous plate.
