Bosch 18102 Premium Wideband Air/Fuel Ratio Oxygen Sensor

The Bosch 18102 is a premium wideband air/fuel ratio oxygen sensor designed to deliver precise exhaust monitoring for optimal engine performance and fuel efficiency. Unlike conventional oxygen sensors that simply switch between rich and lean readings, this advanced wideband sensor accurately measures the exact amount of oxygen in the exhaust gases, providing the engine control unit (ECU) with proportional signal data for superior air/fuel mixture control.

Key Features:

• Advanced wideband sensing element for precise air/fuel measurement and enhanced catalyst efficiency
• OE-type direct-fit connector and harness for straightforward installation
• 18mm thread diameter with pre-applied anti-seize compound for easy installation right out of the box
• 5-wire heated sensor design for rapid operation and accurate readings in all conditions
• 12.5-inch (318mm) wire length for proper routing and connection
• Robust sensor construction with seared protection tube for increased longevity
• Subjected to 1,000°C functional testing and leak testing for environmental and functional durability

As the original inventor of oxygen sensor technology, Bosch delivers unmatched quality and precision. Every sensor is rigorously tested to ensure it meets strict OE specifications for reliable performance, reduced emissions, and optimal fuel economy. A failing oxygen sensor can lead to excessive fuel consumption, elevated emissions, reduced catalytic converter life, and diminished engine performance—making timely replacement with genuine Bosch components essential for maintaining your vehicle's efficiency and performance.
