AEM X-Series Wideband + iWire Plug-and-Play
Wideband data without a wiring project.
Get a clear, real-time view of your engine’s air/fuel ratio with the AEM X-Series 52mm gauge and iWire’s vehicle-specific plug-and-play wiring. Spend less time figuring out electrical connections and more time getting your Subaru build ready to drive.
Whether you’re adding your first wideband or replacing a custom-wired setup, this kit combines the AEM gauge with wiring modified by iWire for the selected application.
What you get
Live AFR readings
See air/fuel ratio information directly on the dedicated AEM X-Series gauge.
Vehicle-specific wiring
iWire prepares the harness for your Subaru, reducing the need to work out the electrical connections yourself.
Two harness configurations
A built-in jumper lets you select the standard gauge-focused setup or an alternate logging configuration for supported applications.
Made for your build
Choose your vehicle from the options above so the kit matches the intended installation.
Important COBB Accessport note: This kit does not provide wideband data logging through post–Green Speed COBB Accessport tuning software. The wideband gauge still displays AFR information in the standard configuration. If ECU logging is essential to your setup, confirm your tuning system supports the alternate configuration before ordering.
Choose how you want to use it
Gauge display, factory rear O2 retained
Displays wideband AFR data on the AEM gauge while leaving the factory rear oxygen-sensor function unaffected by the kit’s logging connection. Wideband-to-ECU logging is not enabled.
For supported alternate logging systems
For applicable off-road/race setups using alternate tuning software or a standalone ECU that can accept wideband information through the rear O2 input. Logging depends on your vehicle and tuning setup; it is not a workaround for post–Green Speed COBB Accessport logging.
The harness includes a jumper so you can change the configuration later. Confirm compatibility with your tuner before using the alternate configuration.
Before you order
- AEM gauge: X-Series Wideband UEGO AFR Gauge, AEM part number 30-0300; 52mm (2-1/16") gauge size.
- Installation: Some routing between the engine bay and cabin, gauge mounting, and wideband oxygen-sensor installation are still required. Exhaust sensor-bung work may be necessary depending on the vehicle.
- Harness availability: iWire modifies the supplied wiring in-house, so the plug-and-play wiring is not sold separately from the unit.
Already have a gauge or prefer the other package? See the AEM wideband kit without the gauge.
Why add a dedicated wideband?
A wideband provides a dedicated, easy-to-read AFR display for your build. The factory front oxygen sensor still performs its original vehicle function; this kit adds a separate gauge and sensor. If you need AFR data recorded alongside other engine parameters for tuning, talk with your tuner about which logging method your particular setup supports.
