If you use a turbo or supercharger to increase your engine’s efficiency, then a boost gauge is a must-have accessory. It monitors the pressure flowing into the combustion chamber. Low pressure is inefficient, while high pressure can blow the engine. Therefore, the gadget ensures optimum pressure for enhanced engine performance. Here are the best aftermarket boost gauges to assist you in keeping an eye on your engine.

  • Best Overall
    GlowShift Boost Gauge

    This gadget reads your vehicle’s boost levels from 0 to 30PSI and compression levels from -30 to 0 inHG, ensuring there’s no over boost to damage your engine. It features an illuminated red needle for easy viewing.


    It features a seven-color dial LED lighting system for enhanced visibility, even during night driving. Also, it comes with free lifetime technical support, which suggests it is durable.


    One disadvantage of this gauge is that calibrations are not visible during the day. Professional installation is required to be able to use the indicator properly.

  • Best Value
    Bosch Mechanical Boost Gauge

    The gauge features a 0-20 PSI boost and a 0-30 inHg vacuum scale with a 270-degree sweep for fast pressure monitoring. It has a standard black dial with white calibration, a red needle, and internal backlights for enhanced visibility. 


    This gauge is durable and easy to install and read. Also, its combination of colors enhances the look of your dashboard. Additionally, it is accurate and affordable.


    The gauge makes a buzzing noise when the boost is big. Also, its included tubing is stiff, and it does not come with the tee fitting needed for a complete installation.

  • Honorable Mention
    AEM UEGO Air/Fuel Ratio Gauge

    For an executive and technological gauge, consider the AEM Boost gauge. It features a digital LED display and sweeping LED pointer that changes colors for better viewing. Its 52mm housing ensures that it will fit in most gauge pods.


    The gauge comes with black and silver bezels and black and white faceplates for multiple color combinations, thus making it possible to customize your dashboard. It shuts down before any damage occurs. The gauge has quick alerts if air/fuel ratio changes.


    This gauge is very expensive. Also, professional installation is required to ensure proper operation and a perfect fit.
