How to Switch Out an Old Boost Gauge in a 2004 WRX

The 2004 Subaru Impreza WRX comes equipped with a boost gauge to allow you to see the turbocharger pressure. The boost gauge is installed in the upper column cover and can be replaced in a matter of minutes provided you have the appropriate tools. To access the gauge, you will need to remove the steering column covers. The Subaru boost gauge part number is H5010FE050, but there are also several aftermarket boost gauges you can install. You just need to make sure they are compatible with the Impreza WRX.
