AEM digital boost gauge 52mm. This gauge delivers a precise accuracy, and visibility that you can rely on. Each gauge includes a 24 color coded (Red, Green, and Yellow) LED lights that will change from green to yellow to red for immediate reference to the boost levels, and an integrated three-digit display will reveal real-time boost.
The 52mm gauge will fit in most gauge pods for convenient installation, and can be remotely mounted virtually anywhere. Included are interchangeable silver and black bezels, and black and white faceplates to personalize the look of your gauge.
The AEM Digital Boost Gauge uses an absolute manifold pressure sensor, which means at higher elevations, it will not exactly zero out as there is less atmosphere at elevation.
