Sorry to burst your bubble... BUT:
* Intake pipe:
- Hole - either already there or drill one = free
- 90 degree bend - provided you have a FMIC not using the original hole, you will have a standard one lying around = free
- Piece of pipe to put in bend - Bunnings? PVC Tube from Plastic store? = $10 max?
- 2 x 3" hose clamps = $10?
* Pod bracket:
- completely unecessary with the heat shield holding the AFM in place
- or if you must, and you have an Apexi kit, it comes with the bracket
- or if you don't, piece of aluminum and bend, drill two holes and mount = $5 for off cut of aluminum
* Heat Shield:
- sheet metal = $50 max for more than enough to make the shield
- rivets / bolts = $5
I don't believe we've even hit the $80 mark yet...
