Product Overview
AEM X-Series Boost Pressure Gauge 30-0306 (-30inHg to 35 PSI)
The AEM X-Series boost gauge combines a large, bright numeric readout with a ring of 24 green LEDs that sweep like a traditional needle, so you can read exact boost or vacuum at a glance. It covers -30 inHg to 35 PSI (-1 to 2.5 bar), which suits most turbocharged and supercharged road and track cars, and fits a standard 52 mm (2-1/16″) gauge pod.
Features
- Centre LED display 87% larger than AEM’s earlier digital gauges
- 24-LED outer ring acting as a sweeping needle
- Two face buttons for peak recall, imperial/metric units and warning thresholds
- User-set threshold warning to flag overboost
- Auto-dimming for comfortable night driving
- Very slim body: under 0.825″ overall depth, 0.200″ cup depth
- Positive-locking connectors
Outputs and integration
Alongside the display, the gauge broadcasts its reading on AEMnet CAN-bus and provides a 0–5 V analogue output. This lets you daisy-chain it to an AEM Infinity ECU, Series 2 EMS, AQ-1 data logger or other device that supports AEMnet, or log boost on a third-party logger without adding another sensor.
What’s included and fitting advice
Supplied with a black bezel and a double-sided black faceplate (PSI one side, bar the other), plus the wiring and vacuum line needed for installation. A silver bezel and white faceplate are available separately in AEM’s 30-0306-ACC accessory kit. Take the boost/vacuum reference from a port on the inlet manifold after the throttle body, route the line away from heat, and connect power to an ignition-switched feed so the gauge does not drain the battery.
