Mercury Zephyr Air Fuel Ratio Gauges 

Available in analog and digital versions, Mercury Zephyr air-fuel ratio gauges will let you know when your engine is operating in the safe zone. Too much fuel will bog your engine down, while too much air will lean it out and cause catastrophic failure! Our Mercury Zephyr air-fuel ratio gauges are available in both wide-band and narrow-band versions depending on your needs, and every Mercury Zephyr air-fuel ratio gauge includes a wiring harness and detailed instructions.
