GlowShift Turbo Boost & Vacuum Gauge 2-1/16" (52mm) 0–30 PSI Tinted 7-Color LED Mechanical Sensor

GlowShift Tinted 7 Color 30 PSI Turbo Boost Vac Gauge Kit is a 2-1/16" (52mm) mechanical gauge that displays turbo boost from 0–30 PSI and vacuum from -30–0 inHg with selectable illumination colors for dashboard matching.

This compact, all-inclusive boost and vacuum gauge from GlowShift combines a precision mechanical sensor with a customizable tinted lens and seven solid illumination colors plus two cycle modes. It’s built to fit most performance and modified vehicles, and ships with the tubing, fittings, wiring and mounting hardware needed for a straightforward install. The design balances a clear, black dial and illuminated red needle for fast reading with interior lighting options so the gauge integrates with your car’s cabin look.

How accurate is the boost and vacuum reading?

The gauge uses a mechanical sensing element calibrated for automotive boost and vacuum applications, reporting boost from 0 to 30 PSI and vacuum from -30 to 0 inHg. Readings are immediate and analog, ideal for monitoring turbo or supercharger behavior in real time without digital lag.

• Range: -30 inHg (vacuum) to 0 inHg and 0–30 PSI (boost)
• 2-1/16" (52mm) diameter for standard performance gauge pods
• Mechanical sensing avoids dependency on vehicle ECU mapping
• Clear red needle and black dial provide high contrast for quick checks

What installation parts and wiring are included?

The kit arrives with the essential hardware and a step-by-step instruction sheet to guide a DIY installation or support a professional install. Included parts let you tap into manifold pressure safely while routing the gauge lighting to your dash or headlight circuit.

• 6' silicone hose and 1/8" T-fitting for vacuum/boost line hookup
• Two hose clamps to secure vacuum connections
• 2' power wire plus dimmer lead to link with headlight switch
• Mounting bracket, visor and hardware for secure dash mounting

How do the lighting and color modes work inside my vehicle?

The tinted lens houses a multicolor LED system with seven solid colors and two color-cycle patterns so you can match factory illumination or add a custom accent. The dimmer wire can be tied to your headlight switch to automatically reduce brightness about 30% when lights are on and cut glare for night driving.

• Seven fixed colors: blue, red, green, teal, purple, white and yellow
• Two cycle modes let colors rotate for a dynamic display
• Dimmer wire reduces brightness when headlights are engaged
• Tinted lens gives a subtle, integrated appearance in a dark dash
