Prosport Air Fuel Ratio Gauge, EVO Series, Blue, 52mm, Digital

• Complete EVO Wideband Kit for AFR Monitoring and Installation: This Prosport EVO Series wideband digital air fuel ratio gauge kit is built for enthusiasts who want a full AFR setup in one package without piecing together separate components. The kit includes the 52mm digital gauge, Bosch LSU 4.9 five-wire heated O2 sensor, weld-in bung, instructions, decals, a 10-foot gauge-to-sensor wiring harness, and plug-and-play wiring. That complete layout makes it a practical option for project cars, tuned street vehicles, and performance builds that need a dependable oxygen monitoring component with modern digital visibility.
• Selectable Blue and Red Display with Blackout Face Styling: This EVO Series gauge features a selectable blue or red digital display, allowing drivers to choose the lighting color that best fits their interior style and visibility preference. When the vehicle is off, the blackout face, black bezel, and black case help the gauge blend cleanly into the dash for a more integrated appearance. Once powered on, the central readout and outer bar-graph LEDs create a bold, technical look that feels right at home in custom cabins, tuner builds, and motorsport-inspired interiors.
• Bosch LSU 4.9 Sensor with Broad AFR Visibility: Built around a Bosch LSU 4.9 wideband oxygen sensor, this kit is made to provide real-time AFR information across a broad 10.0:1 to 20.0:1 display range. That level of visibility helps enthusiasts monitor engine fueling behavior during startup, idle, cruising, acceleration, and higher-load operation with greater confidence. Whether the vehicle is naturally aspirated or boosted, the sensor and digital display combination supports clearer insight during tuning work, drivability checks, and general engine performance observation.
• 270 Degree Style Sweep with Thin EVO Housing: The EVO Series is designed to offer quick one-glance readability through a 270 degree style digital sweep and outer LED bar-graph layout that makes AFR changes easier to follow while driving. Just as important, the thin housing measures only about 1.5 inches deep including the studs, making it especially useful for tighter mounting locations. That slim profile gives installers more flexibility when working with compact pods, custom dash panels, or other spaces where a deeper traditional gauge body may be more difficult to fit.
• Dimmable Display and 0-5 Volt Data Logging Output: In addition to its eye-catching dual-color presentation, this wideband gauge includes adjustable brightness to support more comfortable viewing in both daytime and nighttime driving conditions. It also provides a 0-5 volt output signal for data logging, giving tuners and advanced users more than just a visual in-cabin reference. That output can help support wider tuning and diagnostic workflows by allowing AFR information to be captured, reviewed, and applied during dyno sessions, garage adjustments, and long-term performance monitoring.
