The AEM 35PSI Analog Boost gauge is perfect for those who want a precise non-digital display boost gauge to know how much boost they are running. The 320 degrees of resolution makes it easy to see when there's even a 2 PSI change in pressure, so you can quickly recognize if something has changed in your set up of boost controller. The lightning fast needle movement is a result of a precision high speed electronic stepper motor making it one of the fastest and most accurate gauges available. A 50 PSIA brass sensor gives the gauge its accuracy. The backlighting is user adjustable to 7 colors, allowing users to easily match the boost pressure gauge to most factory gauge clusters. Each gauge comes with interchangeable black & silver bezels and black and white gauge faceplates for multiple color combinations.

This gauge uses an absolute pressure sensor which means at higher elevations it will not exactly zero out as there is less atmosphere at elevation.
