Spectra OS6280 Premium Heated Oxygen Sensor Thimble Type - 4-Wire

The Spectra Premium OS6280 is a heated thimble-type oxygen sensor (O2 sensor) designed as a direct OE replacement. Featuring a 4-terminal rectangular male connector and an overall length of 26-9/16 inches, this sensor is engineered to restore proper exhaust monitoring and fuel management to your vehicle's engine control system.

How It Works:

The oxygen sensor continuously monitors O2 concentration in the exhaust stream and communicates that data back to the ECU, enabling the engine management system to optimize fuel delivery and maintain efficient combustion. A failing O2 sensor can result in reduced fuel economy, rough idle, and degraded ignition timing.

Key Features:

• Heated sensor design — reaches operating temperature quickly for faster closed-loop feedback
• Thimble-type sensing element with robust manufacturing process to ensure accurate, consistent performance
• 4-wire, rectangular male connector — exact electrical match to the OE vehicle wiring harness
• Fully waterproof connectors resistant to car wash spray, puddle water, dust, and other external conditions
• Anti-seize coating applied to threads for easier installation and future serviceability
• Protective shipping cap shields the sensing element during transport
• Manufactured under ISO 9001 and TS16949 quality management standards covering raw materials, in-process controls, and final inspection
• Extensive computerized testing validates real-world performance before shipment
• 100% new construction — no core charge required
• Spectra part number engraved directly on the sensor for easy identification

Spectra Premium O2 sensors are assembled by specialized workers in a dust-free environment using components stored in a controlled-temperature facility, ensuring repeatable quality on every unit. The OS6280 meets or exceeds OE performance standards and installs without modification.
