Bosch Premium Wideband Oxygen Sensor

The Bosch Premium Wideband Oxygen Sensor (also called a wideband O2 sensor or air/fuel ratio sensor) measures the oxygen content in the exhaust stream over a broad range of air/fuel mixtures. It sends accurate data to the engine control unit so the ECU can fine-tune fuel delivery for efficient combustion, lower emissions and good drivability.

Key Features:

• Wideband sensing technology that reads a wide range of air/fuel ratios, including lean and rich conditions
• Built to meet original equipment specifications for fit, form and function
• Heated sensing element for fast warm-up and stable readings
• Durable housing and protected wiring designed to withstand exhaust heat, vibration and road contaminants
• Supports efficient fuel economy, lower emissions and smooth engine performance
• Backed by Bosch, a long-standing OE supplier and a pioneer of the oxygen sensor

A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle and higher emissions. Replacing it with a quality wideband sensor helps restore proper engine management and emissions control. Select the child item that matches your application.
