Since the launch of the HP Tuners nGauge, we've seen some really creative mounting solutions. The two most popular are the suction mount and the AC vent mount.
The most trick looking is the AC mount, and it really doesn't affect cooling as much as you'd think, as the AC simply blows harder out of the other vents.
The video below shows how easy it is to mount our AC vent adapter ring. We have one that works for S550 mustangs and another for 2005-2014 F150.
