Gauge EVO Wideband Air Fuel w/ Sensor Prem

The Gauge EVO Wideband Air Fuel with Sensor Premium is a professional-grade wideband air-fuel ratio monitoring system designed for serious tuners, engine builders, and performance enthusiasts who demand real-time combustion data. This 2-1/16 inch digital gauge reads across the critical 10.0:1 to 20.0:1 AFR range, providing the precision feedback required for safe and efficient engine calibration during custom tuning, dyno sessions, or street performance builds. Whether you're optimizing a naturally aspirated engine, managing a forced-induction setup, or verifying fuel mapping on a standalone ECU, accurate air-fuel ratio monitoring is non-negotiable for preventing detonation, maximizing power, and protecting your investment.

The PROSPORT Gauge EVO Wideband operates via an electric wideband oxygen sensor that samples exhaust gas composition with far greater resolution than traditional narrowband O2 sensors, capturing subtle changes in combustion efficiency across the entire fuel spectrum. The digital display features selectable blue, green, red, and white LED illumination, allowing visibility in any lighting condition and easy customization to match your interior aesthetic. The premium sensor package included in this kit eliminates guesswork during installation and ensures reliable signal transmission to the gauge head, while the robust black-face design resists glare and maintains readability during high-intensity driving or tuning sessions on the dyno.

This system benefits anyone serious about engine performance—from weekend track warriors and drag racers to professional shops running full custom builds and turbo conversions. Installation requires mounting the 2-1/16 inch gauge head on your dashboard or pod, routing the sensor into the exhaust stream (typically via a bung in the header or cat-back piping), and connecting the wiring harness to vehicle power and ground. The compact dimensions (7.4 x 3.3 x 11 inches) ensure flexible mounting options in tight engine bays, while the included premium sensor eliminates compatibility concerns common with aftermarket oxygen sensor sourcing and tuning accuracy.
