The Prosport 52MM White and Amber Wideband Air Fuel Ratio Kit has been designed for you to provide good insurance for your engine. If you don’t know where your air/fuel ratios are, and if you continue to run your car hard then you risk either leaning your engine out, or even washing a cylinder.
The Prosport Wideband Air Fuel Ratio Gauge features the latest Bosch wideband O2 sensor which is a 5-wire heated LSU 4.9, and Prosport Inc. is the only one in the USA to use them. This wideband range reads from 10.0.1 to 20.0.1 AFR readings. This particular wideband O2 gauge will be blacked out once powered off.
Also features with this wideband gauge is a 0-5 volt output signal for data logging, and 0-1 volt output signal to connect to your ECU. Included in this gauge is the Bosch 4.9 5 wire heated O2 sensor, weld-in bung, gauge hood, wiring harness, and instructions for installation.
