Spectra OS5356 Premium Oxygen Sensor OE Replacement

The Spectra Premium OS5356 is a direct-fit replacement oxygen sensor (O2 sensor) engineered to restore proper exhaust gas monitoring and fuel management to your vehicle. The oxygen sensor measures the O2 concentration in the exhaust stream, allowing the engine control unit (ECU) to optimize the air/fuel mixture for maximum fuel efficiency and reduced emissions.

Key Features:

• 100% performance tested to meet OE vehicle requirements before leaving the factory
• Exact electrical connector match to the vehicle's mating harness for a true plug-and-play installation
• Anti-seize coating pre-applied to threads to simplify installation and prevent future seizing
• Protective cap included to shield the sensing element from dirt and contamination during transport and storage
• Robust sensing element manufactured using a controlled process to ensure consistent specifications and performance
• Waterproof connectors resistant to car wash spray, puddle splash, dust, and other environmental conditions
• Manufactured to ISO 9001 and TS16949 quality management standards covering raw materials, in-process quality, and final inspection
• All installation accessories included: rubber grommets, tie wraps, and push-in clips
• No core charge required — completely new part, not remanufactured
• Spectra part number engraved directly on the part for easy identification

A failing oxygen sensor can decrease fuel economy, cause rough engine idle, trigger a check engine light, and negatively affect ignition timing. The Spectra Premium OS5356 is built in a dust-free environment using a strict quality control process, ensuring it delivers reliable, long-lasting performance as a direct replacement for the original equipment sensor.
