Some strategically placed duct tape and the removal of the plastic guard on the hood net a smoother intake flow w/o warranty issues.
I taped over the 'appendages' for sound deadening that branch off the main intake. Coupled with the removal of that silly thing on the hood, the car is the slightest bit louder and feels like it breaths a little better at higher rpm. Nothing to write home about mind you, but its a small improvement.
Heck I was thrilled and impressed that FHI bothered with a detail like that.
