I'd say by filter volume alone, while being shielded from the majority of the under hood ambient temps, this should make some gains in power. Over an open end filter and OEM box. Insulating that box will be key as you have done to help with heat soak.
Looks great honestly!
It's just the fact that they have it on EVERY other vehicle, or least offered, across the lines. Having to buy a Lariat and then a $5k Lux group just to get XM and SYNC on a Mav??? Mehhhhhh
