It uses a 5-wire design with a rectangular female connector and metric M18 x 1.5 threads for direct-fit service on supported applications.\u003c\/p\u003e\u003cp\u003eCompatible with Alfa Romeo Giulia and Alfa Romeo Stelvio applications, this NTK air\/fuel ratio sensor helps the engine control unit read mixture changes with linear signal output rather than simple rich-or-lean switching. The result is tighter air-fuel correction for efficient combustion and lower emissions.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWide-band air\/fuel ratio sensor for precise mixture feedback\u003c\/li\u003e\n\u003cli\u003eHeated design for faster operating response\u003c\/li\u003e\n\u003cli\u003eSpecific-fit configuration for direct replacement service\u003c\/li\u003e\n\u003cli\u003e5-wire technology with blade terminals and rectangular connector\u003c\/li\u003e\n\u003cli\u003eMetric thread size: M18 x 1.5 with 7.00 thread length\u003c\/li\u003e\n\u003cli\u003eBlack connector housing and standard replacement grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eNTK 27094 is engineered as a direct-fit 5-wire A\/F sensor for upstream applications on the Alfa Romeo Giulia and Alfa Romeo Stelvio. The wide-band sensing element provides a linear output signal, allowing the ECU to make continuous air-fuel adjustments instead of relying on a simple switching signal. That control supports stable combustion, fuel efficiency, and emissions management. The part number 27094 is also referenced for OE-style service applications, and 27094 cross-references 68315196AA for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIncorrect air-fuel mixture readings\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to sensor performance\u003c\/li\u003e\n\u003cli\u003eReduced fuel economy from inaccurate mixture control\u003c\/li\u003e\n\u003cli\u003eElevated emissions from poor combustion control\u003c\/li\u003e\n\u003cli\u003eSlow or unstable sensor response in closed-loop operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eInstall as a specific-fit upstream sensor on the listed applications. Verify the M18 x 1.5 thread size, 5-wire configuration, and rectangular female connector before installation. The sensor uses a heated design and a blade-terminal connection; confirm harness routing and connector indexing match the original layout. Part number 27094 should be matched to the vehicle application before replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eNTK is a major OEM oxygen sensor supplier with broad OE application coverage and in-house ceramics expertise used in wide-band sensor production. Part number 27094 is built to standard replacement specifications for direct-fit service.\u003c\/p\u003e","brand":"NTK","offers":[{"title":"Default Title","offer_id":53621586428085,"sku":"BFPZ-27094","price":79.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/NO_27094_Fro.jpg?v=1793168212","url":"https:\/\/www.partcatalog.com\/products\/ntk-27094-air-fuel-ratio-sensor-upstream","provider":"PartCatalog","version":"1.0","type":"link"}
