Removing the cold-air inlet...
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...
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.
Given the Coyote's throttle...
Given the Coyote's throttle body location front and center, the cold-air inlet (PN 1774, $329.99) is a remarkably simple unit. BBK found the amount of projection of the inlet tube into the conical air filter critical; get it wrong and power plummets.
