• Driveability concerns caused by aging exhaust monitoring components

Installation Notes

Verify the sensor position before ordering, since this part is used in both upstream and downstream locations. Confirm the VIN or chassis break notes shown in the fitment list for Volkswagen Golf, Jetta, and Passat applications, as well as the VIN cutoff for Audi A4 and A4 Quattro coverage. For best results, compare the connector and sensor location on the vehicle before installation.

Quality Assurance

Spectra Premium uses engineering, manufacturing technology, and quality control processes to produce oxygen sensors that meet or exceed the performance of the original equipment they replace. This part number is OS5020.
