A while back, I saw a write up on improving the stock HVAC box. Essentially, it consisted of adding a wedge shaped plenum between the fan and the box, to expose more of the evaporator core to the air flow, along with some other improvements. Trouble is, I can't remember where I read it; here, in the poca newsletter, or elsewhere. Can anyone point me in the right direction? TIA, Rodney
