That just a spoof that replaces the IAT sensor. It tells the ECU that the inlet temp is lower (usually a fixed value). In theory, it could add HP if the ECU is programmed to aggressively reduce timing at warmer inlet temps. Personally, I would not bother with it.
If you are so inclined, remove your IAT sensor, place it in the fridge for five minutes, then remove it and use an ohm meter to get the resistance value across the sensor. You can go to your nearest Radio Shack and pick up a resistor of the same value for less than a buck.

This product is going to trick your cpu into thinking its sucking lower air temp so the engine advances timming more. Its like your are driving your engine cold all the time, but when hot weather comes there will be trouble.
I also drive a 98 Explorer V8 with intercooled 13 psi Powerdyne supercharger. This vehicle has a air meter and a separate air sensor. I moved the air sensor at the outside engine compartment along with the KN air filter. This does trick works extremely well, especially with cool weather like around 68 degrees, but when 90 to 100 degree weather hits, you better lift off the gas pedal or there is going to have a blown head gasket.
But I think AMG has some safety feature installed to prevent that and retard the timming.

The MB world is in the tuning dark ages. Its just a piggyback air fuel computer, with fixed preset variables. It tricks the IAT signal going to the ecu. Similar devices have been used in other application since 1989. S-AFC, HKS VPC..ect. I would guess it sets the inlet temp at a constant 66* like the HKS VPC.
