Prosport’s JDM Series 52mm Wideband Air/Fuel Ratio Gauge will display Amber and White Analog and Blue Digital at the same time.

It 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 a Dual color (Amber, white) Analog readout in the center of the gauge with trailing LED’s around the outside of the scale plate AND a Blue Digital display for immediate reference to AFR.
