2-1/16in DG/B Nitrous Pressure Gauge

The AutoMeter 2-1/16in DG/B Nitrous Pressure Gauge is a precision digital instrument designed for high-performance nitrous oxide systems. This electric gauge reads 0–1600 psi and is engineered to provide accurate real-time monitoring of system pressure during nitrous injection, making it essential for tuners and engine builders who demand reliable data during boost events. The 2-1/16-inch diameter dial fits standard gauge clusters while the black face delivers clear visibility under all lighting conditions.

The 0–1600 psi range covers both single-stage and progressive nitrous setups commonly found in drag racing, street performance, and forced-induction builds. Digital display technology eliminates parallax error and needle bounce, providing consistent readings even under heavy vibration—critical when monitoring system integrity at full throttle. The electric sensor operates independently of mechanical linkage, ensuring durability and minimal drift over extended use. This AutoMeter gauge is built to the standards expected in competitive motorsports environments where fuel system pressure and nitrous delivery precision directly impact power output and engine safety.

This gauge is ideal for owners of turbocharged, supercharged, or naturally aspirated performance vehicles running aftermarket nitrous systems. Whether tuning a street car, road racing vehicle, or dedicated drag racer, accurate pressure monitoring prevents over-pressurization that can damage injectors or plumbing. The compact 2-1/16-inch size allows integration into existing dashboard gauge pods or custom gauge clusters without requiring substantial fabrication. Installation requires basic electrical and line connections, making it accessible to both professional shops and experienced DIY builders.

AutoMeter's Sport-Comp line is recognized for combining durability with precision in high-vibration applications. The digital format reduces maintenance concerns associated with mechanical gauges, while the 1600 psi ceiling accommodates modern high-flow nitrous bottles and multi-stage delivery systems. Black-face gauges coordinate with most interior styling while maintaining professional appearance in both street and track environments.
