2-5/8" A/F WB | Complete + O2 Sensor

Standalone Air/Fuel Gauge keeps you informed on your engine’s air/fuel mixture with a complete, self-contained system built for clean installs and accurate tuning. With a built-in wideband controller and included O2 sensor, it removes the need for external components while delivering precise AFR data in real time. Designed to show how your engine is running during idle, cruising, and acceleration, it helps you dial in performance and catch lean or rich conditions early. A built-in warning light alerts you when AFR moves outside your target range for added protection. A precision stepper motor keeps the needle smooth and steady—no fluctuation, no guesswork. Built with a durable housing and solid aluminum bezel, it’s made for demanding conditions and long-term use. Made in the USA and backed for life.
