Spectra OS5011 Premium Oxygen Sensor OE Replacement

The Spectra Premium OS5011 is a direct-fit replacement oxygen sensor (O2 sensor) engineered to restore proper exhaust gas monitoring and fuel management to your vehicle. Designed to OE specifications, this sensor delivers the precise fit, form, and function of the original equipment it replaces.

How It Works:

The oxygen sensor monitors the concentration of oxygen in the exhaust stream and communicates that data back to the engine control unit (ECU). This allows the ECU to continuously optimize the air/fuel mixture for peak fuel efficiency, performance, and low emissions. A failing O2 sensor can result in reduced fuel economy, rough engine idle, and disrupted ignition timing.

Key Features:

• OE-matched performance — engineered to meet or exceed original equipment specifications
• Robust sensing element — manufactured using a precision electronic process in a dust-free environment
• Exact connector match — plug-and-play electrical connector fits the vehicle's OEM wiring harness
• Anti-seize coating — pre-applied to threads to prevent galling and corrosion during installation and service
• Protective transport cap — shields the sensing element from contamination prior to installation
• ISO 9001 & TS16949 certified manufacturing — quality management standards applied throughout raw materials, production, and final inspection
• 100% performance tested — every unit undergoes computerized testing to verify real-world performance before shipment
• Comes complete — includes all required accessories such as rubber grommets, tie wraps, and push-in clips
• Part number engraved on sensor — for easy verification during installation
