It's almost time for these to start shipping! My HD is now running a preproduction version of the complete system. I installed it to check fitment and to see if any other tweeks are needed before the production versions start going out. Everything looks good! I just need to modify one bracket that bolts the scoop to the radiator support. This truck has a set of Flex-a-lite 290 fans so the one of those brackets is in the same location that I would use for this.
The shroud that you see when the hood is opened needs to be removed (about 7 plastic "pop screws"). The scoop draws air from behind the grill . It is sealed to the hood so air passed through it and then fed to the airbox.
