Prosport’s Evo Premium Series 60mm Wideband Air/Fuel Ratio Gauge provides data on exactly how rich or lean an engine is running at any load. This Gauge is essential when tuning any performance vehicle on or off the Dynometer. Allowing you to closely tune and monitor your vehicles air to fuel ratio. This results reduced emissions, higher fuel economy, and maximized power.
Utilizing the latest Bosch wideband O2 sensor -5 wire heated LSU 4.9 (Prosport Inc. is the only one in the USA to use them) our gauge now has the widest range 10.0:1 to 20.0:1 AFR readings on the planet.

Featuring four color choices in one gauge (Red/Blue/Green/White) with a huge 52mm digital readout in
the center of the gauge and a bar-graph style LED’s around the outside of the gauge for immediate reference to AFR.
All Premium series EVO gauges have 7 stages of dimming for both day and night driving.
