Nissan Fairlady/300ZX Z32 Knock Sensor

Terra Firma Automotive supplies genuine Nissan engine management components that protect and optimize the performance of your Z32 Fairlady or 300ZX. This knock sensor is the exact OEM detonation sensor engineered to detect harmful pre-ignition and engine knock in real time. Mounted directly on the engine block, it sends critical acoustic signals to the ECU, allowing instant adjustments to ignition timing and boost levels to safeguard the VG30DE and VG30DETT engines from damage while maintaining maximum power and efficiency under all driving conditions.

Z32 owners restoring or tuning their cars know that a failing knock sensor can trigger check engine lights, reduce timing advance, limit boost on twin-turbo models, cause hesitation, or leave the engine vulnerable to detonation damage. Replacing it with this authentic unit instantly restores precise knock detection and factory ECU response, delivering smoother power delivery, stronger boost response, and reliable protection whether you are daily driving a naturally aspirated model or pushing high horsepower on a twin-turbo build. Its robust construction and factory-calibrated sensitivity ensure accurate performance in the high-heat, high-vibration environment of these legendary V6 engines.

At Terra Firma Automotive, we are the trusted premium source for hard-to-find OEM sensors and engine electronics that serious enthusiasts and professional builders rely on. Whether you are troubleshooting detonation codes, refreshing the engine management system during a performance rebuild, completing a full engine bay restoration, or maintaining an original low-mileage example, this knock sensor upholds the precise engineering and protective intelligence that define the 1989–1996 Fairlady Z and 1990–1996 300ZX
