What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn downstream sensor
• Emissions test failures tied to sensor response issues
• Rougher fuel control caused by degraded exhaust feedback
• Replacement needs for a damaged or aging factory sensor

Installation Notes and Tips

Verify the vehicle year, make, model, and downstream position before ordering. Confirm the 4-wire connector style, 18 mm threaded mounting, and 22-inch harness length against the original sensor. Use the listed fitment notes for emissions package details such as Federal Emissions and build-date-specific coverage on the 1998-1999 Nissan Maxima.

Quality Assurance

NTK is a major original equipment oxygen sensor supplier and tests these sensors during manufacturing to help meet or exceed OE specifications. The Direct Fit Oxygen Sensor line is built to support accurate fitment and dependable operation on the specified Nissan and INFINITI applications.
