Monitor your air/fuel ratio and boost with this AEM 2-gauge kit, which pairs the AEM 30-4110 Classic Digital Wideband UEGO Air/Fuel Ratio Gauge with the AEM 30-4406 Classic Digital Boost Gauge. The wideband gauge uses a Bosch LSU 4.9 sensor with faster light-off and lower current draw than the earlier LSU 4.2, and it never requires free-air calibration. Its LED "needle" changes color from rich to lean and responds to changes as small as 0.1 AFR.
The boost gauge reads from 30 inHg vacuum to 35 PSI boost, showing boost in 1 PSI increments on a three-digit center readout with a 24-LED outer ring. Both gauges use a standard 52mm (2-1/16") housing and include a 0-5V analog output for data loggers and engine management systems such as the AEM Infinity ECU, Series 2 EMS or AQ-1 Data Logger. Auto-dimming lighting and interchangeable bezels and faceplates come with each gauge.
