AEM Digital Wideband UEGO Gauge

AEM Wideband AFR Gauge, the honest tool you use to keep your tune out of the danger zone

Why enthusiasts choose this gauge

• Real accuracy where it counts, AEM pairs this AEM gauge with Bosch sensor support using the Bosch 4.9 LSU sensor when you choose the Sensor Yes option. You get a fast response and tight resolution, so when you stab the throttle and boost ramps, you actually see the mixture move instead of guessing.
• Easy to read at a glance, the AEM digital AFR gauge gives you a big three digit LED readout in 0.1 steps, plus a perimeter light ring that shifts rich to lean. On a hard pull you do not want to squint, you want to know if you are drifting lean before you hear the bad noises.
• Works with the stuff you already run, this digital wideband gauge AEM includes 0 to 5 V analog output and AEMnet CAN, so it plays nice with standalones, piggybacks, and loggers. It fits the plug-and-play wideband gauge role in the sense that you wire it, mount the sensor, and start logging, no calibration gas routine.
• Standard sizing and clean look, it is an AEM 52 mm wideband, so it drops into most 2 1 16 pods. You also get black and silver bezels and black and white faces, so it does not scream aftermarket unless you want it to.
• Built for real cars, not just dyno queens, it handles heat and vibration without turning into a flickering Christmas ornament. We run AEM wideband AFR gauge setups on our own cars because it makes tuning and troubleshooting faster, not because it looks cool.

Perfect for: an AEM wideband for turbo cars where you want to verify AFR under boost, NA builds where you chase repeatable power, ethanol swaps where fueling margin gets thin, and anyone making an accurate wideband gauge buy instead of gambling a motor on vibes.

Installation Snapshot: Intermediate DIY, about 1 hour. You get the harness and hardware, and you get the Bosch 4.9 LSU sensor gauge setup if you pick Sensor Yes. The kit includes a weld in stainless bung, so plan on welding that into your exhaust. Choose your variant: SKU: AEM-30-4110 | Sensor: Yes, or SKU: AEM-30-4110NS | Sensor: No. If you are ready to buy AEM wideband gauge, watch for an AEM wideband gauge sale and you can knock out your AEM UEGO gauge
