GlowShift Boost Gauges and Boost Vacuum Gauges help drivers monitor boost pressure or vacuum/compression levels with pinpoint accuracy. Benefits include better fuel economy and improved engine efficiency.

Boost gauges help you catch any unusual spikes to avoid overboosting and protect your engine. Boost Vac gauges alert you to any air leaks in the system or a leaky valve which can lead to rough idling and increased emissions.

When it comes to deciding on the right version for your car or truck, there are a few key factors to take into consideration. The first is size with 2-1/16” (52mm), 2-3/8” (60mm) and 2-5/8” (65mm) gauges in stock.

Boost pressure gauges tend to be used more with diesel applications where the engine does not create vacuum. Boost vacuum gauges are used on gasoline engines with a turbo or supercharger where the engine will produce vacuum at idle AC and go into a C positive boost pressure while driving.

We have a wide range of both options for you to choose from. Whether we’re talking classic cars and trucks with a carburetor or another type of low boost application, or modified cars and trucks and racing applications, we’ll have the right boost gauge or boost vac gauge for you.

You can also customize the look of your gauge with a GlowShift Gauge Series. Go with an analog or digital display, clear or tinted magnified lens, and multiple color options for the LED display.

Each boost gauge kit has you covered with everything you’ll need for installation. Depending on the gauge it’ll have an electronic boost pressure sensor, 9’ of Boost Hose, 1/8-27 NPT Brass Compression Fittings, 6’ Silicone Hose, Hose Clamps, 1/8” T-Fitting, wiring and other parts.

Find the right boost gauge or boost vac gauge for your car or truck to maximize engine performance and enhance the interior of your application at the same time.
