We carry a pretty comprehensive lineup of Digital and Analog Wideband Air Fuel Ratio Gauges that give you a reliable display of Rich, Optimal and Lean levels. These gauges are a strong addition to any performance vehicle and will help you get better fuel efficiency too.

The latest version we developed is our Needle (Analog) E85 Wideband Gauge, which displays air-to-fuel ratios from 6 ~ 12 AFR quality values. This gauge is calibrated specifically for any car or truck that runs on Ethanol 85 fuel.

Each gauge is featured as part of our 7 Color Gauge Series, which comes with a black or white gauge face, clear or tinted magnified lens, and 7 color options for the LED display. We have a Tinted 7 Color, Black 7 Color and White 7 Color version of the gauge.

E85 Flex Fuel is one of the most common fuel types in most markets, which is one of the reasons why it’s popular. These cars and trucks run on basically any mixture of gasoline and ethanol, up to E85. Another reason drivers use Ethanol 85 is because it tends to be cheaper than gas. Some flexible fuel vehicles (FFVs) also get increased horsepower on E85 versus regular gas.

This is why we wanted to make a gauge for drivers that prefer E85 to a standard gas engine. We know there are a lot of you out there, and you should have a Wideband AFR Gauge that is geared towards your fuel type. So if you have a car or truck that runs on flex fuel, check out our Ethanol 85 Wideband Air Fuel Gauge which we made specifically with you in mind.
