Its no easy task getting a cold air feed in to the CDA and similar.
The problem if no cold air feed is lack of or less power than standard air box arrangement.
Ryan mine basically resembles that cant remember much did it back in August. Your CDA needs to be positioned much further back towards the rad and alum tube shortened as well- CDA outlet end of the box needs to be very close to the rad top mounting rubber, the other end tilting down a lot more unless going through front bumper.
As i see it there are only three options.
Louvre the wing with some means of attaching some tubing to it and open up the inner wing two skins. Rule out bonnet venting which would need to seal to the cold feed tubing upon closing the bonnet. Hole through as standard is way too small and too far to the side, needs to approach the strut more with at least an 80mm dia plus wall thickness of tube used. Dress the cut edges, paint and use that plastic edging strip. Think mine was 95 x 90mm oval cutout.
Do away with the aircon and piping use the areas which it occupied, more power in its own right! 240 degree bend within 8" width and such like in confined areas, not many tubing products will flex to that small a diameter! Feed through with a collapsable tube (aluminium) where the aircon was and should clear the alternator and radiator. Move one of the horns and inlet through the outside front lower grille where there is no slots. Various other areas in this region.
Lastly figuring it could be a no return jobby and easier to replace the front bumper or conceal it should anything go wrong is the other option. This has its own flaws as well, massive hole in inner wings (two skins to cut) (a repo saw comes in handy 1/2 lb+ of steel removal it will shock you) 90 degree bend fed in at an angle. Will need to cut half the bumper/ front wing bracket and re strenghen it up (can get 4" up but needs to collapse oval like. Make an air intake and adapter to fix to the lower bumper (used two 4" dia round x 16mm lg aluminium which thread together and clamp to the side of the bumper with a mesh insert colour coordinated.) Other problem for most will be no flat surface any where, hence why i screw cut 1mm metric fine it pulls in flat when tightened by hand.
The original standard air intake used to rub on the soundproofing. Similar layout to above piccy i have 1" of clearance on underside of bonnet with soundproofing removed.
No piccies my daughters got my camera down in Cardiff, thats the last i will see of that.
