If you're looking at an AEM Wideband you have likely modified your car and need to keep an eye on air-fuel ratios. This gauge does exactly that, and does it extremely well. A wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. Air/fuel readings are very consistent and the wideband gauges have an excellent reputation for accuracy. Included is AEM's wide band oxygen sensor and everything needed for a quick and easy wideband install. Additional face plates and bezels are also included so you can customize the look to better match your boost gauge or OEM instrument panel! Buy yours today and begin monitoring your Air Fuel Ratios before it's too late...


The Wideband allows you to control, and accurately monitor your Air/Fuel Ratio as a quality, and cost effective tuning tool. The AFR gauge monitoring tool provides accurate data that is essential to a safe and powerful tune.


The 30-4110 wideband gauge is easy to read, highly accurate, and controls its data by a digital LED display and LED needle that will change colors as the ratios change from rich to lean. Utilizing a Bosch 4.9 LSU sensor.
