Spectra OS5576 Oxygen Sensor

Spectra OS5576 Oxygen Sensor

The Spectra OS5576 oxygen sensor is an OE-style emission control replacement for select GM, Saab, Saturn, and Porsche applications. Built to meet or exceed original equipment performance targets, it supports accurate exhaust feedback for proper engine management and emissions control.

• Downstream and upstream fitments across multiple vehicle platforms
• Direct replacement for Bank 1 Sensor 1 and Bank 1 Sensor 2 applications where listed
• OE-level engineering and manufacturing quality control
• Cross-references Delphi ES20011 and NTK 25727 for the same application
• Fits select Chevrolet Sonic, Trax, Cruze, and Cruze Limited models

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback to the engine control module
• Reduced emissions system efficiency
• Rough idle or drivability concerns tied to sensor signal issues
• Failed emissions inspection caused by a faulty upstream or downstream sensor

Installation Notes

Confirm the exact position before ordering, since this part is listed for upstream, downstream, left, and right applications depending on vehicle. Match the vehicle year, make, model, and sensor location to the fitment table, and verify Bank 1 Sensor 1 or Bank 1 Sensor 2 placement where noted. The Spectra OS5576 is a direct-fit replacement for the listed applications, including Chevrolet Sonic, Trax, and Cruze coverage.

Quality Assurance

Spectra Premium states that its engineering, manufacturing technology, and quality control are used to produce oxygen sensors that meet or exceed the performance of the original equipment they replace.
