AEM offers a -30 - 35 PSI boost gauge and 0-60 PSI boost gauge. Each gauge offers a swept area of 320 degrees for the best viewing resolution at almost any angle. A precision high-speed electronic stepper motor delivers lightning-fast needle movement, making AEM's boost gauges some of the fastest and most accurate gauges available. An included sensor provides accurate boost readings for the gauge. All AEM analog boost gauges feature seven backlight colors that allow you to match your OEM or other gauge backlighting, a silver and black bezel, and a white and black faceplate to best match the interior of your vehicle. The backlighting is adjustable via a dial on the rear of the gauge to optimize viewing in all lighting conditions.
