This manual is in no way definitive instructions on how to fit Gauges to an Impreza. It has merely been compiled as a guide to illustrate the parts I have used in order to fit them to my vehicle. It is designed as a source of reference only. Hope you find it useful !
For my new age Impreza I decided to fit a Turbo Gauge and Oil Pressure Gauge.

These instructions have been designed for unaltered vehicles. Before you start, check for any variations. Each vehicle may dictate it’s own control mount and cable routing. Therefore, you will need to study the pictures and use your good judgement or seek professional help. Lift kits may govern how and where the cable is routed. Always keep the cable away from heat (exhaust) and rough or sharp edges. If you are concerned about lower cable damage or abrasion, we recommend cutting a length (about 3 feet) of 5/8” ID plastic or rubber hose (garden or heater) to be slid over the cable before assembly. Please keep in mind, the warranty is void on heat damaged or abused cables. Before drilling, check for any electrical wires, hoses, etc.

Bob and I appreciate your purchase of your HyperBoost Valves from Stratmosphere. Please read these instructions prior to installation so that you can enjoy a simple and quick installation of your new HyperBoost valves!

Step 1- Remove motor cover
This is the small triangular cover in the front of the engine where the dipstick is located (figure 1). Just twist the two screws 90 degrees counterclockwise. Then lift up the cover. The cover fits onto a rubber round mount at the point on the “triangle” as well. It’s just pressed on there.
