For BMW E90 E91 E92 E93 E60 E61 E63 E64 325i 330i 520i 530i NOX Sensor Nitrogen Oxygen OEM: 11787587129

Feature: The nitrogen oxide sensor has undergone multiple rounds of road mileage testing; under normal driving conditions, the ceramic sensor for element exhibits a gradual rate of performance degradation Function: The NOx sensor synchronises oxygen concentration with NOx data; the electronic control unit corrects the air-fuel ratio to balance power output and exhaust emission parameters Installation: For the NOx sensor, check the clearance from high-temperature components in the vicinity and allow sufficient for space for heat dissipation to minimise wear and tear on the wiring harness caused by prolonged exposure to heat.
