The first photo shows the earlier 2008-2010 CAI -- it has the advantage of being specifically designed for the earlier models. The second photo is perfectly legit but doesn't capitalize on the front fascia inlet. My guess is the earlier version is superior in performance, but the second is definitely not bad -- way better than OE. Guess it depends on what you're really trying to achieve!

I have to agree with TrevorS. Looking at the instructions from the Sparks Scion page, the new orange/black style:
  • replaces the OEM inlet tube with a shorter one
  • uses a new TRD air filter
  • uses a metal tube after the filter box
  • (re)uses the lower half of the OEM filter box
Since they reuse the lower half of the OEM filter box, the new filter cannot be any bigger in footprint than OEM but only less restictive. Maybe you can use a TRD filter in a stock OEM filter box?

Also, why they don't include a new slotted fascia vent to actually get cold air to the new CAI inlet is beyond me.

Of course, you can always cut your own slots in your OEM fascia vent. That's what I did...
I use a TRD filter in my stock lower air box, a 3" intake pipe, the TRD fascia vent, and a 3" TB pipe. Works great, but as you can imagine, required a little effort :)!
