The top of the flex tube is heading toward the stock fender opening, the same opening all 4G CAI's use...
and stops just below the frame (green oval below), I didn't see any benefit to crushing it to go any further.
The "Difference" is instead of relying on the TB's ability to "suck" air up from the mostly enclosed lower fender area behind the bumper's dead air space
It's now Front "Forced" live air that's Rammed
up there from forward momentum
I still might try and fab a rectangular shaped funnel to match the bumper opening,
then mod the plastic lower grill surround and make it a functional Honeycomb grill to match the upper one.
Similar to what MGH did in front for his inter-cooler on his twin turbo setup:
