      Performance Series Gauge. When you have a tuned engine, close monitoring is necessary. This is the reason why you have different gauges on your vehicle's dashboard. For close monitoring of your Jeep Wrangler, ProSport offers the 52mm Performance Digital Air/Fuel Ratio Gauge. It is designed to let you know the amount of air that enters the engine in relation to the fuel present and whether the numbers are within normal operating range. For a complementary dash look, this gauge features an elegant Amber LCD display and readout.

      Precise Air/Fuel Ratio Monitoring. The right mixture of air and fuel in the engine tells you whether your vehicle’s engine is functioning properly and efficiently. So, you need to make sure that you are only getting accurate air to fuel ratio. This ProSport Digital AFR Gauge will help you accurately monitor the air to fuel ratio in the engine. It offers the widest range of 10:01 to 20:01 AFR readings with its Bosch wideband O2 sensor that features -5 wire heated LSU.

      Elegant Additional Feature. This 52mm Wideband Air/Fuel Ratio Gauge has Amber LCD readout in the center and a bar-graph style LEDs around the side. The bar-graph changes from green (Rich) to Yellow (Optimal) to Red (Lean) and lets you know about the state of your engine’s air to fuel ratio. For a complete look, this gauge is blacked out when turned off and is illuminated amber with the digital readout.

      Consistent Quality. Known as a brand that produces only the best quality gauges, ProSport offers only top-notch products including this Performance Digital AFR Gauge. You get a gauge that is meant to provide long-lasting service and hassle-free AFR monitoring.
