Autometer Replacement Wideband Air/Fuel O2 Pro Plus Sensor

This is the replacement O2 sensor for AutoMeter's Pro Plus wideband air/fuel ratio gauges. It uses the well-known Bosch LSU 4.9 sensor, which is a popular choice for its accuracy and reliability in monitoring your engine's air-fuel mixture. Having a precise reading from your wideband gauge is crucial, especially if you've made modifications to your engine or fuel system, as it helps you tune for optimal performance and prevent costly damage from running too lean.

The LSU 4.9 sensor is known for its fast response time, meaning it can detect changes in your air-fuel ratio quickly. This is important because rapid changes can indicate potential issues that need immediate attention. This sensor is designed to be a direct replacement for the sensor that originally came with your AutoMeter Pro Plus wideband gauge, ensuring a proper connection and accurate readings without needing any complex modifications.

When replacing an O2 sensor, it's a good idea to check the condition of the wiring harness and any associated connectors to ensure they are clean and free of corrosion. This helps maintain a solid electrical connection, which is vital for the gauge to receive accurate data from the sensor.
