2" 52mm Car Boost Meter | Electronic Boost Gauge with 7-Color Backlight and Alarm

Keep an eye on your engine's boost pressure with this 2" 52mm electronic boost gauge. It covers a display range from -1 to 2 Bar (-30 to 30 PSI) and includes a programmable alarm to warn you when pressure goes outside your set limits. The 7-color backlight lets you match the gauge to your dashboard style.

This gauge is built for universal fitment on any 12V vehicle. The digital readout gives you precise pressure information at a glance, helping you monitor turbo or supercharger performance. The alarm function adds an extra layer of protection by alerting you to potentially harmful pressure levels.

You can change the backlight color directly from the gauge buttons. Whether you prefer a subtle white or a vibrant red, the choice is yours. This makes it easy to integrate the gauge into your existing interior lighting scheme without extra wiring or controllers.

The package includes everything you need for installation: the gauge itself, a boost sensor, a 6-foot PVC hose, a T-fitting, wiring, and an English manual. The sensor uses a standard 1/8 NPT thread, which is common on many aftermarket boost ports.

Key Features and Benefits

- Electronic boost gauge with a display range of -1~2 Bar / -30~30 PSI that provides accurate pressure readings for your forced induction system.

Who Is This For

- Car enthusiasts who have installed a turbocharger or supercharger and need to monitor boost pressure.

Usage Scenario

Mark just finished installing a turbo kit on his daily driver. He needed a way to keep track of boost pressure without constantly looking down at a small display. He mounted this 52mm gauge in a pillar pod, set the alarm to sound at 25 PSI, and now he can focus on the road. The bright 7-color backlight makes it easy to read at night, and the alarm gives him peace of mind that he won't accidentally over-boost his engine.

Micro Comparison

Many mechanical boost gauges rely on a simple needle and tube, which can vibrate or lag. This electronic gauge gives you a precise digital readout and adds a programmable alarm that mechanical gauges often lack. The 7-color backlight also offers more customization than single-color gauges, letting you match your dashboard or mood.
