I think that short 90 degree bend piece between the throttle body and the air flow sensor is from a 3.2L.
Anyways, it's a tight fit but i didn't have to cut any sheet metal for all that to fit, the air filter tucks into the area under of the engine bay that's under the rear trunk lid, meaning it's protected from rain even when running an open GT engine lid.
Oh, and yes, that's a Gatorade bottle posing as a overflow catch can.
