I have experimented quite a bit with cold, cool, and warm air intakes on my Acura, and have found the optimal temps to be in the 125-140F range, with no ill effect on timing (stays between 29-45 degrees advance during cruising speeds.) Though to be fair, I am also running a VAFC, tuned accordingly.

As far as O2 being king of the **** castle, yes, this is true to an extent, but it does have it's limits, I can lean out my VAFC to the point where the ECU throws Bank 1 Lean codes, even though 02 correction parameters are unaffected by the VAFC.
