Product Description

Autometer Ultra-Lite Narrowband 2-1/16 Air/Fuel Ratio Gauge
Running too lean while enjoying spirited driving in your vehicle is one of the leading causes of expensive engine damage. AutoMeter’s Narrowband Air/Fuel Gauges pair with older Oxygen Sensors to warn of lean burn conditions under heavy engine load. Connects directly to the factory O2 sensor on many applications, or uses the AutoMeter 2244 Narrowband O2 sensor. Not compatible with 5 wire air/fuel sensors.This Autometer Ultra-Lite Narrowband 2-1/16 Air/Fuel Ratio Gauge is compatible with factory narrow-band O2 sensors. May require Autometer's model 2244 if the vehicle does not have a factory narrowband primary o@ sensor. This gauge features a LED radial bar graph display, and does not have provisions for backlighting. This Autometer gauge will not work with Wide Band O2 sensors, please check your application.

Air-Fuel Ratio (AFR)
Air-fuel ratio is the mass ratio of air to fuel present during combustion. When all the fuel is combined with all the free oxygen in the combustion chamber the mixture is chemically balanced and this air to fuel ratio (AFR) is called the stoichiometric mixture (often abbreviated to stoich). AFR is an important measure for anti-pollution and performance tuning considerations.
