Description

The AEM 30-4110NS is a wideband gauge kit designed to monitor Air/Fuel Ratio (AFR). This controller gauge and hardware are sold without a wideband sensor, allowing users to source a Bosch 4.9LSU sensor separately. It features a 52mm (2-1/16") gauge housing with a digital LED display and a sweeping LED "needle" that changes colors to indicate AFR shifts from rich to lean. The gauge offers a 0-5v analog output for the 10-20 AFR range and does not require free-air calibration.
