Well Chad (FluiDSVT) and I have been playing with the design for this thing for a while now and we've got a version we are ready to sell. We tried a bunch of different setups to see what worked and what didn't. We're pretty happy with the results so far. We've found a thermal coated shield reduces the intake temps by on average 30-40 degrees over the temps just outside the shield in the engine bay. Lower air temps = more HP!
The shield is designed to minimize the effects of hot underhood air on cars equiped with an open element air filter like the KKM, BAT, CTA, and similar systems. We liked the power gain from the greater surface area of our open element filters, but hated the fact that they were so sensitive to high underhood air temps. Our goal was to design a shield that blocked the hot air from it's main sources - the engine and radiator. Anyone who's driven their car in slow traffic or in hot weather can attest to how "flat" the engine can feel.:(
Here is a pic of the shield in NECO member highgeer's Cougar.

One note here - this is
NOT a cold air intake. The heatshield is closed on four sides and seals to the hood with a rubber gasket. This effectivly blocks the hot under hood air and creates a cooler area that's fed by the stock fender draw.
True cold air induction can be easily (and cheaply!) added by first removing the driver side wheel and fender liner then installing some 3" dryer hose that's routed to the lower grill and held in place by a few zip ties. You have now added a great source of cold air! This makes our shield even more effective.
There have been a few posts here on CEG covering the cold air subject in the past. A search thru the archives should cover all the bases and answer most questions. We recommend the hose not be connected directly to the filter but placed just inside the open end of the box in order to fill the entire shielded area with cold air.
Well, we hope you guys like it.
