As a direct-fit replacement, it matches the specified OE application and is intended for upstream installation where accurate mixture monitoring is critical to engine management. The 18 mm thread diameter and 27.5-inch harness length support the listed fitment, while the heated design helps the sensor reach operating temperature efficiently.\u003c\/p\u003e\u003cp\u003eNTK’s Direct Fit 5-Wire A\/F Sensor line focuses on application-specific coverage and OE-style integration. This part cross-references Volkswagen Group 06K906262C for the same application. Use NTK 27056 when replacing the original sensor on compatible Volkswagen GTI, Jetta, and Golf variants, as well as the Audi A3 applications shown in the fitment table.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a failed upstream air\/fuel ratio sensor\u003c\/li\u003e\n\u003cli\u003eRestoring accurate fuel mixture feedback to the engine control system\u003c\/li\u003e\n\u003cli\u003eAddressing sensor-related fault codes or drivability concerns\u003c\/li\u003e\n\u003cli\u003eCorrecting slow sensor response or unstable signal output\u003c\/li\u003e\n\u003cli\u003eSupporting emissions system performance on the listed vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the connector, thread size, and upstream Bank 1 Sensor 1 location before installation.
