Knock sensor from an Infiniti FX35/FX45 (2003–2008). This sensor detects engine detonation and relays that signal to the engine control unit so it can adjust ignition timing and prevent damage. Verify OEM fitment against your original unit before ordering, as sensor placement varies by engine configuration.
