      Innovative Two-in-One 52mm Gauge. There’s no need to waste valuable space in your passenger cabin with too many gauges when you run the Digital Air Fuel Ratio & Volt Gauge from Prosport. The innovative design features an air-fuel ratio readout around the outside of the gauge, with a blue digital readout in the center of the gauge. The digital readout can be set to read only air-fuel ratio, or cycle between AFR and digital voltage readout.

      Supports Both Narrowband Stock and Wideband Bosch Aftermarket Sensors. Not only do you get the incredible power of the combined display in the Digital Air Fuel Ratio and Volt Gauge but you also get the power of using a stock narrowband oxygen sensor that covers 0-1 volts or an aftermarket 0-5 volts wideband Bosch heated O2 sensor. The choice is yours!

      Installs with Stock O2 Sensor. For narrowband sensor operation, the Gauge works with your stock O2 sensor. For use with a wideband O2 sensor, you’ll need an additional controller, which is not included.

      Application. The Prosport Digital Air Fuel Ratio and Volt Gauge works with 1966-2023 Jeep CJ and Wrangler models.
