Bosch Oxygen Sensor Original Equipment

The Bosch Original Equipment Oxygen Sensor (also called an O2 sensor, lambda sensor, or air-fuel ratio sensor) measures the oxygen content in the exhaust stream and sends that data to the engine control unit. The ECU uses it to fine-tune the air-fuel mixture for efficient combustion, good fuel economy, and low emissions.

Key Features:

• Bosch invented the automotive oxygen sensor and supplies many vehicle manufacturers as an original equipment (OE) supplier.
• Engineered to match OE form, fit, and function for dependable performance.
• Gives accurate exhaust gas readings so the engine management system can control the air-fuel mixture.
• Helps the catalytic converter work efficiently and supports emissions compliance.
• Built to hold up to high exhaust temperatures, vibration, and harsh operating conditions.
• Many applications come with a pre-installed connector or pigtail for plug-and-play installation.

A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle, and higher emissions. Replacing it with a Bosch Original Equipment oxygen sensor helps restore proper engine management and fuel efficiency.
