For 6 7 Series E63 E64 E65 E66 630i 730li 525xi 530xi 11787545244 Downstream Oxygen Sensor This sensor directly replaces the part that has stopped working correctly due to age or contamination. Reinstating proper exhaust monitoring helps keep the engine management system running as intended. The electrical connector clicks directly onto the factory harness without any cutting or crimping. This design saves time and reduces the chance of wiring mistakes. A flexible stainless steel sleeve protects the signal wires from sharp edges, engine heat, and road debris. Long cable life is maintained even in harsh under‑vehicle conditions. The threaded portion is shaped to match the sensor’s bung size and pitch. This exact fit prevents exhaust leaks and keeps the sensor secure during driving.
