Uh, how is this better than putting the gauge in the factory vent? The trim is chrome and doesn't match anything and it probably has to be trimmed/sanded to fit anyways. A desk grommet from Office Depot fits absolutely perfectly in our stock vent and only requires minimal trimming on the inner surface to fit the gauge through. No painting, no fuss, no muss. Then you have the folks who complain about air blowing on the back of their gauge and say it must be blocked off. But this one clearly blows air on the back of the gauge and allows a little to pass by around the gauge rim and now everyone says "its okay" and a "better" option? Sure, sure ...
