All vehicles will lose some degree of performance due to heat soak under the right operating conditions. BMW integrated the intake air temp sensor in the MAF housing several models, including those powered by the N52. Compensating for this false hot air measurement, the ECU pulls timing and runs a richer fuel mixture, resulting in a significant loss of torque.

Turner designed an IAT relocation kit that moves the intake air temp sensor to a cooler location. The result is you’ll experience reduced torque loss and more consistent power output when you’re pushing your engine hard.

Just wanted to clarify: Is what this kit does is bypass the portion of the MAF molex and instead gets a signal from a dedicated IAT which is positioned further up the airstream before the filter box?

Since I don't want to assume, based on your 4th picture in the link, it comes with a new dedicated IAT (with a nut and a gripped washer) that we would drill a hole for and secure from the inside of the inlet passage. The bypass cable single end would be plugged into the existing MAF harness and then the Y-split pieces would go to the current MAF (which stays in position) and IAT respectively?
