The factory intake (over the top of the radiator) is not optimal, but directs ambient air to the filter. And the plastic from which it is manufactured has a low thermal value, so is slow to transfer heat energy from the surrounding environment (of the intake assembly) to the air within.
This version has a "still air" box with SOME isolation from the remainder of the engine bay, but where is the ducting feeding fresh, ambient air to the intake? It looks to me like this system simply uses air leakage around the headlight to fee the intake. If that is the case, not good at all.
Pretty colour though.

The aFe intake uses the same air inlet port as the factory intake. When the hood is closed a box is formed using the partition walls, hood and front of the engine compartment. The only opening in this box is the inlet port for the factory intake. It's basically just a bigger box with a different filter.
The only time heat transfer from the engine bay makes much of a difference is when the engine is at idle and vehicle isn't moving. Once the engine revs up and the vehicle is moving the air going though the filter is close to ambient temperature.
