Spectra Premium OS6246 Oxygen Sensor with Top Side Connector OE Replacement

The Spectra Premium OS6246 is a direct-fit OE replacement oxygen sensor (O2 sensor) featuring a top side connector configuration. Designed to restore proper exhaust gas monitoring and fuel management, this sensor communicates oxygen concentration data back to the vehicle's ECU, enabling the engine management system to maintain optimal fuel efficiency and reduce exhaust emissions.

Spectra Premium oxygen sensors are assembled by highly trained specialists in a controlled, dust-free environment under ISO 9001 and TS16949 quality management standards, covering everything from raw material storage to final inspection and shipment. Each unit undergoes 100% performance testing before leaving the facility.

Key Features:

• Top side connector design for precise OE-match fitment
• Exact electrical connector match to the vehicle's mating harness
• Anti-seize coating pre-applied to sensor threads for easier installation
• Fully waterproof connectors — resistant to car wash spray, puddle splash, and dust
• Protective cap shields the sensor during shipping and storage
• Manufactured under ISO 9001 and TS16949 quality standards
• 100% performance tested to meet OE vehicle requirements
• All installation accessories included: rubber grommets, tie wraps, and push-in clips
• Brand new — no core charge required

Replacing a faulty oxygen sensor restores accurate air-fuel ratio feedback to the ECU, improving fuel economy, smoothing engine idle, and preventing ignition timing issues caused by degraded sensor performance.
