Where to buy this part:
The use of gauges is a must on a modified 1.8T. Especially a boost gauge. Not only is it cool to see the boost rise but it is a great device to troubleshoot any problems that may be causing a loss of power. Other popular types of gauges are oil pressure, oil temperature, air/fuel ratio and exhaust gas temperature.
Prices range from $50-150 depending on the sytle and type of gauge.
