narrowband afr air-fuel ratio gauge kits for performance sport car

The purpose of the AFR gauge is to measure the air-fuel ratio of the engine, and prevent the vehicle from being too rich or too lean, and avoid high maintenance costs. AFR gauge is divided into two types: narrowband and wideband AFR. The difference between the two is that the wideband air fuel meter can provide you with information about the internal combustion engine, while the narrowband uses your car’s factory oxygen sensor to display its air-fuel ratio. Although the failure of the air-fuel ratio meter is rare, your oxygen sensor may need to be calibrated to provide you with the correct data logging.
