Fuel/Air Monitor Only, Rectangular

Click for a larger picture of Fuel/Air Monitor Only, Rectangular

The K&N Air/Fuel Monitor is designed to help with jetting or injector settings on any engine running on unleaded gasoline, alcohol, propane or nitrous oxide. The 3-color LED gauge displays your engine's air-fuel ratio from Lean to Rich.

This square unit has a built-in bracket for mounting on top of a dash. The gauge is designed for use with a Single-Wire Oxygen Sensor (Part No. 3882, sold separately). If your vehicle is already equipped with a one-wire oxygen sensor, you can just tap into the existing sensor wire rather than installing a separate sensor.
