O2 Oxygen Sensor Upstream Downstream for Nissan 370Z (2011-2013) 3.7L

Direct-Fit Oxygen Sensor Kit for 2011-2013 Nissan 370Z (Z34)

What it Does: The complete upstream and downstream O2 sensor kit replaces worn factory lambda probes on the 2011-2013 Nissan 370Z to restore precise closed-loop air-fuel ratio monitoring and eliminate diagnostic trouble codes.

The Stock Nissan 370Z Sensor Degradation

The high-revving VQ37VHR engine operates under high thermal loads and aggressive exhaust gas velocity. Over time, factory zirconia elements suffer from severe silicon contamination, carbon fouling, and internal heater element fatigue. Degraded sensors output sluggish voltage signals to the ECM, causing inaccurate fuel trimming, unburned hydrocarbons that overheat catalytic converters, poor fuel economy, hesitations under load, and persistent check engine lights (P0130, P0150, P0420).

The Engineering Solution

This 4-piece sensor package is engineered for direct OE drop-in replacement across both banks of the Z34 exhaust stream. Built with fast-acting planar ceramic sensing cores and double-layered laser-welded stainless steel protective shielding, these probes resist thermal shock, particulate fouling, and vibration degradation. Factory-matched weather-pack pigtail connectors ensure plug-and-play integration without cutting, splicing, or pinning harness wires, restoring instant closed-loop stoichiometric fuel feedback.
