Default "power output stage N122"? what is it and what does it do on 99.5 models?

<img src="http://198.170.177.107/aw/air_intake.gif">

the actual sensor is #3 in the above picture of the airbox. the underside is attached to a heat sink whish sits exposed on the bottom side of the roof of the factory air box.

here's a schematic .. N122 .. which looks attached to the coil packs.

anyone know what this part does?
