Are you that guy? You know, the guy with big, gaudy and ugly gauges all over the dash and door molding? I don't judge you because the fact that you have so many gauges, sometimes people need to actively monitor other systems not included in the stock gauges, I just judge you because the placement of said gauges. Roush has a solution for owners of any 2005 to 2008 Ford Mustang or 2004 to 2008 Ford F-150. These gauge pods from Roush fit inside of the vents in the cooling/heating system of the Mustang and F-150 and hold any gauge you could ever dream of.
The vent gauges require no drilling and don't obstruct a substantial amount of airflow, either. The $30 price tag simply includes a pod that fits in the Mustang or F-150's vent. The pod can then hold a standard 2 1/16-inch gauge of your liking. [Roush]
