4pcs Oxygen Sensors Set Compatible with Audi A4 A4 Quattro 2004-2002 3L V6 - Upstream & Downstream O2 Sensors (234-5028, 234-4874) - Perfect for Engine Performance & Emission Control

Product Description

Advantages of KUHTYB O2 Sensor: ● Low power consumption(7watt) ● High temperature resistance (vent at 1000 ℃) ● Multilayer ceramic belt structure with integral heater and low quality active area. ● The very short activity time (<15 seconds) reduces the discharge during cold start. ● There is no need to adjust and repair the oxygen sensor, just replace the same type of oxygen sensor. Part Includes: 4 wire-Oxygen Sensor: Upstream 2X4 wire-Oxygen Sensor: Downstream 2X Need Your Attention: Please use the year/make/model drop down bar confirm the compatibility before purchasing. And make sure our part number is the same with your existing one before purchase!
