Specs At A Glance

Good To Know

Q: Does this set include both the upstream and downstream sensors? A: Yes, the set contains one upstream air fuel ratio sensor and one downstream O2 sensor for the exhaust layout of the 2013-2017 Nissan Altima.

Q: Should I reset the ECU after installation? A: Clear trouble codes with an OBD-II scanner so the engine computer can relearn fuel trims and recognize the new sensor signals right away.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
