maf and throttle body diameter

For the AOS, I had to flip the T upside down, since the AOS is on the opposite side in the 996. I bonded a piece of PVC into my AOS as one fitting, then cut the factory fitting going into the T as the other fitting. Between them I have run a piece of rubber heater hose, secured on each end with screw clamps.
I'd like to ditch the factory AOS altogether and run a Moroso unit, plumbed in with stainless hose.

One more note, the bigger TB and change in the position caused by the different T causes the intake tubing to rub the engine cover. I had to use foam/aluminum HVAC insulation to create a barrier to prevent the intake tube from having a hole rubbed through it.
