This replacement part aligns with OEM standards in material and process, using a high-temperature ceramic substrate and double-layer protective shell to resist heat shocks and chemical corrosion from exhaust systems; measured lifespan comparable to OE, but at a more competitive price. OEM numbers include 1K0998262N, 0258017030, and 07C906262BB, suitable for VW and Audi EA111 and EA888 engine models such as Jetta, Passat, A3, etc. Function: monitor oxygen content in exhaust and feed back to ECU to adjust the air-fuel ratio, ensuring combustion efficiency and proper operation of the catalytic converter. Replacement difficulty is medium; use a dedicated oxygen sensor socket to avoid thread damage; cold-start operation is safer.
