AEM's world-famous Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and a sweeping LED needle that changes color as AFR shifts from rich to lean, housed in a 52mm gauge body that fits most gauge pods. The 4.9 LSU sensor has a faster light-off time and lower current draw than the earlier 4.2 LSU sensor and never requires free-air calibration when used with this gauge, thanks to its factory-calibrated resistor.

FAQ
What sensor does the AEM 30-4110 gauge use?
A Bosch 4.9 LSU wideband sensor with a faster light-off time and lower current draw than the earlier 4.2 LSU sensor.
Does this gauge require free-air calibration?
No, the 4.9 LSU sensor uses a factory-calibrated resistor and never needs free-air calibration when used with this gauge.
Is the 30-4110 sensor interchangeable with the older 30-4100 gauge?
No, the 30-4110 uses a different sensor connector than the 30-4100 and the two are not cross-compatible.
