so with this mod, I assume you're discerning that the reservoir is the culprit for heating the air, and not the lack of flow out of your engine bay? there's a reason I love the hood on my 16, two big air vents letting all that ambient air escape.Ive owned my hellcat for 3 months and my odometer is just under 500 miles. Ive been watching my IAT gauge and its insane to me how hot it gets and quick it rises. Ive seen up to 50 degrees above ambient temp. One thing ive noticed is the intake gets extremely hot on the coolant resevoir side. I like the "OEM" look of the car and wanted to keep this as incognito as possible. Once assembled this can not be seen unless you know its there and you look for it.

This piece of the air box faces the valve cover area

This is the under hood piece might not do a whole lot but anything helps. Hopefully keeps the radiant heat from the hood out of the intake area.

This was a very cheap mod 25 dollars DEI thermal shield from Autozone. I just finished this tonight and have not had a chance to drive. I will post results as soon as I get to test drive.
your redeye hood has nothing for flow through, just flow in....
