A low-volume fix would have a low total price of implementation, so the expense would be just as justified on a per-unit basis as the same fix on a high-volume product (accepting perhaps some slight economies of scale from buying or making 5,000 widgets versus 500,000 widgets).

Like a turbo timer for a turbocharged may extend the life of a turbo.

Hank,
If I'm reading your question correctly, you are looking for before and after IAT2 readings in daily driven scenarios in an effort to justify the expense.
You are not alone in this quest for data.

Milage increase? Yeah right... say I gotta bridge for sale. Anybody interested? 
In stop and go driving (w/o HE fans turned on) the IC fluid temps will be nearly identical after about 15 minutes of slow speed driving.
The real benfiet to a more efficient HE will occur when large amounts of heat are transfered into the coolant via the blower. Drag racing for a 1/4 at a time really won't put that much heat into the system. Road racing would. Also when parked in the pits after a run (w/fans ablaze) you'll see a mild decrease in time it takes to remove heat.
IMO a ice filled type of exchanger and some fans down on the stock HE is a far better bang for the buck.
But what do I know?... Rich

Shhhhhhhhh.... The vendors are trying to keep that info secret..
I have no hidden agenda other than to share what little I know.

Supply and demand.
I went looking for HE fans and found them cheaper elsewhere. Does'nt take but a few minutes on the net to realize many other automotive niche markets are into small fans too. Same thing with generic shaped ice boxes.
But... go try to find a Lightning specific highly efficient HE. You won't. Supply and demand at work in America.
There are some things even I don't want to mess with though. (and will pay though the nose for) My flex-a-lite e-fan comes to mind.

This morning I was testing out the data logging capablilities of the new Preditor Revision software and noticed the intake temps.
With a KB and the old JDM Fluidyne Heat Exchanger the IAT temp was 76 degrees and IAT2 was 99 degrees cruising at 70 mph.
I have a FastAir kit so the IAT temp at 76 degrees pretty much matched the ambient outside temp that was showing on my overhead.
