Nissan Fairlady/300ZX Z32 Oxygen Sensor Left (Twin Turbo)

Terra Firma Automotive supplies genuine Nissan engine management components that restore accurate air-fuel feedback and optimal performance to your Z32 Fairlady or 300ZX twin-turbo. This left-hand oxygen sensor is the exact OEM heated O2 sensor engineered for early 1989–1993 twin-turbo models. It monitors exhaust oxygen content on the driver-side bank and sends precise voltage signals to the ECU, enabling accurate fuel trim adjustments for efficient combustion, smooth idle, strong throttle response, and proper boost control under the demanding conditions of the VG30DETT engine.

Early twin-turbo Z32 owners know that a failing O2 sensor commonly causes rich or lean running conditions, hesitation, poor fuel economy, rough idle, reduced boost response, or check engine lights that hurt drivability and can damage catalytic converters over time. Replacing the left-hand sensor with this authentic unit instantly restores factory-calibrated feedback, delivering crisp performance and reliable emissions compliance. Its heated design ensures fast light-off times and consistent readings even during cold starts or low-speed driving, outperforming generic sensors in the high-heat environment of the twin-turbo exhaust.

At Terra Firma Automotive, we are the trusted premium source for hard-to-find OEM sensors and electronics that serious enthusiasts and professional builders rely on. Whether you are troubleshooting fuel trim issues on your early twin-turbo, performing a full emissions or exhaust refresh, addressing sensor-related codes, or completing a detailed engine bay restoration on your 1989–1993 Fairlady Z or 1990–1993 300ZX, this left-hand oxygen sensor upholds the precise engineering and performance standards that define these legendary Nissan sports cars.
