Everyone one of these intake methods draws from the front of the vehicle. The air intake temp is effected by the hottest thing in the area, the radiator. The fan wash is moving air thru and out of the engine bays outlets. At idle the whole area around the front of the car is effected +- 3/10 degrees, if not more (I will have to go and test air temps one day). On hot days it seems like 50 degrees just walking by one running.

When moving, the temps settle down to atmospheric as the cooler air pushes thru the intake system. No one measures heat soak at idle on performance. The M5 board recommends moving the IAT up stream to get the most performance off idle after heat soak, as the read and react from those sensors is not instant. For the X5, I would drive and enjoy the new intake sucking sounds coming from the engine bay.

The Dinan CAI is one of the mods I would like to do, just on the eye candy level. Nice fit and finish compared to others on the market. The prices accordingly reflect that.
