AEM X-Series OBDII Gauge Kit

AEM X-Series OBDII Gauge Kit (PN 30-0311) | Plug & Play Digital Stream Gauge

Monitor vital engine data effortlessly with the AEM X-Series OBDII Gauge Kit (30-0311). Plugs directly into 2008+ CAN-bus OBDII ports. Read parameters & clear DTCs!

The AEM X-Series OBDII Gauge Kit (PN 30-0311) provides a quick, plug-and-play solution to monitor real-time engine datastream parameters directly from your vehicle's factory CAN-bus network. Designed for 2008 and newer OBDII-compliant vehicles, this 52mm gauge draws power and signal data directly through the supplied OBDII port pass-through cable—eliminating the need for complex sensor wiring or custom sensor taps.

Featuring AEM's signature slim 0.825” mounting depth and a cup depth of just 0.200”, the X-Series chassis mounts easily in standard gauge pods or custom dash cutouts. Its bright, 4-digit LED display is 87% larger than previous models, accompanied by 24 sweeping green outer LEDs for rapid visual tracking. The gauge reads factory engine parameters (such as Boost, RPM, Coolant Temp, IAT, Fuel Pressure, and Lambda) while offering the functionality to read and clear Diagnostic Trouble Codes (DTCs).

Best Uses

1. Real-Time Engine Parameter Monitoring: Displaying critical parameters like intake air temp (IAT), boost pressure, coolant temperature, RPM, or ethanol percentage without splicing wires.
2. On-the-Go Code Diagnostics: Reading and clearing Check Engine Light Diagnostic Trouble Codes (DTCs) directly from the gauge display.
3. Clean & Low-Profile Dashboard Builds: Ideal for tight dashboard spaces or flush-mount pillar pods due to its ultra-shallow 0.825" depth profile.
4. Street & Track Vehicles (2008+): Quickly adding telemetry to modern CAN-bus vehicles without adding weight or extra hardware under the hood.

Features

1. Direct OBDII Plug-and-Play Wiring: Connects directly into the vehicle's factory OBDII port for power and CAN-bus data stream transmission.
2. Ultra-Slim Chassis Design: Standard 2-1/16" (52mm) diameter outer housing with a 0.825” overall depth and 0.200” cup depth.
3. High-Contrast Digital Interface: Features an 87% larger 4-digit central LED display with 24 sweeping green outer LEDs and built-in auto-dimming sensors.
4. DTC Diagnostic Reader: Built-in capability to scan and clear engine Diagnostic Trouble Codes.
5. Positive Locking Harness Connectors: Reversible black bezel and faceplate supplied with positive locking connectors to prevent loose wiring under heavy vibration.

Benefits

1. Hassle-Free Installation: Saves hours of installation time by eliminating extra power leads, ground routing, and engine bay sensors.
2. At-a-Glance Readability: The auto-dimming sensor and expansive LED face ensure crystal-clear visibility in bright sunlight or nighttime driving.
3. Versatile Mounting Options: The shallow body depth allows installation almost anywhere inside the cockpit, including flat trim panels and shallow pod mounts.
4. Instant Diagnostic Capability: Saves money on OBD scanners by letting you identify and clear Check Engine Lights right from your driver's seat.
5. Multi-Parameter Support: Allows switching between available factory PID channels provided by the vehicle manufacturer's ECU.
