My current setup is similar to ShadeTreeMech.

I like this setup.
I cut holes in the underside of the air filter housing. This sucks air that's just passed through the radiator. I capped off the shorkel with duct tape - and cut about a 3/8" (~10 mm.) hole in that tape cap. This reduced the intake "moan" noise considerably. With the snorkel fully capped and big holes in the filter box, the noise is pretty bad for passengers who don't care about FE - and I do have such passengers.

Intake air temps are typically 30-40 degrees above ambient air. In winter I wish it were a bit hotter, in 80-90 deg. weather it seems to top out around 110-120. Air and ECT coolant temperatures all read on the ScanGauge.

My grill is mostly blocked, but is OPEN at the upper part of the radiator in front of where the intake cut holes are. So the air goes thru there and gets warmed. Lower grill is fully blocked in winter, and in warmer weather I remove blocking gradually as needed to keep coolant temps low enough that the fan doesn't kick in (ideally, about 182-198 deg. F., imho).
