AEM X-Series Digital Oil Pressure Gauge – 150 PSI / 10 Bar (30-0307)

Oil pressure is one of the most critical parameters to monitor in any high-performance engine. The AEM X-Series Digital Oil Pressure Gauge is engineered to provide highly accurate, real-time oil pressure monitoring, helping drivers and tuners identify potential lubrication issues before they lead to costly engine damage.

Designed for demanding street and motorsport applications, the X-Series combines advanced sensor technology with exceptional readability and professional-grade functionality. Capable of monitoring pressures up to 150 PSI (10 Bar), this gauge is ideal for high-performance naturally aspirated, turbocharged, and racing engines where precise oil pressure monitoring is essential.

The large central LED display is 87% larger than previous AEM digital gauges, while the sweeping LED outer ring provides instant visual reference during aggressive driving. With programmable warning thresholds, peak recall functionality, CAN-Bus communication, analog outputs, and automatic brightness adjustment, the X-Series delivers professional-level monitoring and integration capabilities.

Trusted by motorsport teams and performance workshops worldwide, AEM instrumentation provides the accuracy and reliability required to protect valuable engine investments.

Carefully selected for builders who demand proven performance without compromise.
