I reinstalled the other half of the air box, with about an inch worth of space between the two halves. Gave it a few revs, it retained a nice quality sound, but (thankfully) gave up some of the resonance and boominess of the halved box.
I also took the liberty to find a better retaining system for the air filter, and covered the engine side parts of the upper intake tract with foil tape to reflect any extra heat away from the system. I left the rest black, because the black should radiated the heat already in the system out.
I need to finish my shifter rebuild and SSK install before taking the car on a proper test drive. I would've been done last night, but something went very, very wrong on the assembly (snapped the shift arm) and now I'm waiting for the new parts.
