Bosch 06K-906-262-CQ Front Upstream Oxygen Sensor OE Replacement

The Bosch 06K-906-262-CQ is an OE-quality upstream (front, pre-catalytic converter) oxygen sensor engineered as a direct replacement for Volkswagen and Audi Group vehicles equipped with the 1.8T Gen3 engine platform. As the inventor of the automotive oxygen sensor, Bosch remains the world's leading manufacturer of O2 sensor technology.

This sensor continuously monitors the oxygen content in exhaust gases upstream of the catalytic converter, providing real-time air-fuel ratio feedback to the engine control module (ECM). Accurate O2 sensor readings are essential for proper fuel trim adjustments, optimal fuel economy, and reduced emissions. A failing upstream oxygen sensor can result in rough running, increased fuel consumption, poor performance, and illuminated check engine lights.

Key Features:

• OE-quality direct-fit replacement — no modifications required
• Heated sensor design for fast closed-loop operation and accurate cold-start readings
• Zirconia ceramic sensing element for reliable, long-lasting performance
• Threaded mounting with 18mm thread diameter for secure installation
• Includes OE-style wiring harness connector for plug-and-play fitment
• Manufactured to original equipment specifications for consistent accuracy

Replacing a worn oxygen sensor restores proper fuel management, protects the catalytic converter from damage caused by incorrect air-fuel mixtures, and helps maintain factory emissions compliance. Apply anti-seize compound to the sensor threads before installation to ensure future serviceability.
