Removing the cold-air inlet on '11 GTs is pretty much the same as it's been for years now; the stock airbox and inlet tube can be lifted off as an assembly as shown. There is a radiator support cover that must be popped off, and there is a through-the-grille secondary inlet that is pulled out as well, but the entire job is simple screwdriver work.

BBK has you move the mass-air sensor from the stock airbox to its inlet tube. An Allen wrench is required and BBK supplies one with the inlet.
