Homemade vented front fenders? Options

[KOU In3]

Ok, so I'm at the junkyard today and I'm picking up some body panels.
Complete rear hatch- no spoiler or wiper
2 Complete doors- Manual windows, no power locks
both front fenders
windshield- mine was cracked
both bumper covers- mine had some scuffs

So I'm looking at those vents in the rear quarter panels. Anyone else pull a car apart and notice that they actually duct air into the cabin? Call me a ricer for making Z3 wannabe fenders but I'm thinking they could be relocated to the front fenders to duct some fresh air into the engine compartment Z3 style. Anyone have any thoughts there? Point them forward to grab some air while moving (induction) or keep them facing rearward to vent hot gasses (vent)? Or are they too small to make a real difference?

Oh and on a side note, I just realized that Frankenstein is sporting parts from somewhere between 12 and 20 different donor cars currently.
