If the air entering the turbo is hotter, then the air exiting the turbo is hotter (assuming that the air in not able to sit in the turbo long enough to obtain temperature equilibrium with it (which it isn't)). This hotter air is cooled down by the intercooler at pretty much the same rate, which means that the air exiting the intercooler is hotter
i am looking forward though to see numbers (temps on intake/intake mani with & without the heat shield..)

That toothpick idea is really genius. I was wondering how I would adapt it to fit the hood.
I am having a hard time trying to decide if I want to make one for my stock intake pipe with the vibrant maf adapter, and amsoil filter, OR if I want to buy a aftermarket intake and build one then.
Great job on the DIY

I was impressed that the OP actually took some measurements to validate the effectiveness of his creation.

Part # 3628-BLACK
Medium NACA Duct, Single Hose
Computer Aided Design (CAD) and wind tunnel testing have been combined to produce these NACA ducts. Attention to detail results in maximum air flow with minimal drag. They are molded from tough, high-impact clear or black plastic. An integrally molded flange (approximately .75" wide on most ducts) makes them easy to install in body panels, air dams or side windows. The outlet nipple is sized to fit our 3" air ducting hose. Approximately 9.5" x 4.5" opening excluding flange.
I modified (cut-up) a stock inlet piece (part # MR379037) and I used a piece of black plastic that I cut out of another part I had laying around, and riveted all this together as shown.

Thanks for all the comments guys. It seems to still be working well. Note the testing was done on one of our typical hot days here in Florida. I suspect the temperature difference will be a lot more when the ambient temperature is lower, like in the 60s or 70s. I'll test it again when it's cooler out and report back.

The cooler the incoming air is the denser it is. More oxygen molecules meaning more power. If you start with a cooler temp to be copressed, warmed back up by turbo compressing it, cooling back down by the intercooler. It will be cooler going.into the motor. I forget what they say the theory is for air temperature to power. But it applies to this setup. Great right up and nice looking piece.
