Spectra OS6171 Premium Oxygen Sensor OE Replacement

The Spectra Premium OS6171 is a direct-fit, OE-replacement oxygen sensor (O2 sensor) engineered to restore proper exhaust gas monitoring and fuel management to your vehicle. Designed and built to original equipment specifications, it delivers accurate readings of oxygen concentration in the exhaust stream, enabling your vehicle's ECU to maintain optimal air-fuel ratio and fuel efficiency.

How It Works:

The oxygen sensor monitors O2 levels in the exhaust gas relative to ambient air and communicates that data back to the engine control unit. A faulty or worn sensor can result in decreased fuel economy, rough engine idle, and disrupted ignition timing — making timely replacement critical to maintaining engine performance and reducing emissions.

Key Features:

• Designed and engineered to OE specifications for a precise, drop-in fit — no core charge required
• Manufactured under ISO 9001 and TS16949 quality management standards covering raw materials, production, final inspection, and shipment
• Built using an electronic manufacturing process in a dust-free environment by specialized technicians
• Raw materials stored in a temperature-controlled environment to maintain component integrity
• Subjected to extensive computerized testing to validate real-world performance
• Robust sensing element manufacturing process ensures product specifications are met
• Anti-seize coating applied to threads for easier installation and prevention of seizing
• Shielded with a protective cap during transport to safeguard the sensing element
• 100% performance and quality tested before shipment
• Comes complete with all accessories needed for installation

Spectra Premium oxygen sensors are completely new units — not remanufactured — and are backed by a brand with over three decades of expertise in engine management, fuel delivery, and emissions components for passenger cars and light trucks.
