Bosch OE Type Fitment Heated Thimble Oxygen Sensor

The Bosch OE Type Fitment oxygen sensor (also called an O2 sensor or lambda sensor) is a heated thimble-style sensor. It monitors the oxygen content in the exhaust stream and sends that signal to the engine control unit. The ECU uses it to fine-tune the air-fuel mixture for better fuel economy, lower emissions and smooth engine performance.

Key Features:

• OE type fitment: Built to match the original sensor's form, fit and function, so installation is straightforward and no modification is needed.
• Heated design: An internal heating element brings the sensor up to operating temperature quickly. This allows closed-loop fuel control sooner after a cold start.
• Thimble-style sensing element: The robust ceramic element gives dependable, accurate readings over the life of the sensor.
• Pre-installed connector and wiring: Direct-fit sensors are designed to plug into the factory harness. Many include a pre-applied anti-seize compound on the threads to help with installation.
• Quality engineering: Bosch has been a leading oxygen sensor developer and supplier to vehicle manufacturers for decades. The brand is known for precision manufacturing and rigorous testing.

A worn or failing oxygen sensor can cause poor fuel economy, rough idle, a check engine light and higher emissions. Replacing it with a Bosch OE type sensor helps restore proper fuel control and emissions system performance. Select the correct child item for your application.
