It is built for Subaru models that use a 5-wire sensor configuration and is engineered to match OE fit, form, and function.\u003c\/p\u003e\u003cp\u003eThis NTK sensor uses a 16-inch wiring harness, an 18 mm thread diameter, and a 0.38-inch thread length. The heated design supports faster sensor operation, and the specific-fit layout helps simplify replacement on Subaru Ascent, Legacy, and Outback applications.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDirect-fit replacement for specific applications\u003c\/li\u003e\n\u003cli\u003eHeated air\/fuel ratio sensor design\u003c\/li\u003e\n\u003cli\u003e5-wire configuration\u003c\/li\u003e\n\u003cli\u003e16-inch wiring harness length\u003c\/li\u003e\n\u003cli\u003e18 mm thread diameter with 0.38-inch thread length\u003c\/li\u003e\n\u003cli\u003eMounting bracket not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed application coverage\u003c\/h2\u003e\u003cp\u003eFits 2021-2022 Subaru Ascent, upstream.

This part cross-references Subaru 22641AA79A for the same application. For buyers searching for a Subaru Ascent upstream air\/fuel ratio sensor, Subaru Legacy upstream oxygen sensor replacement, or Subaru Outback direct-fit sensor coverage, NTK 27081 matches the listed OE-style application.\u003c\/p\u003e\u003ch2\u003eWhat it helps address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFault codes related to air\/fuel ratio sensing\u003c\/li\u003e\n\u003cli\u003eRough idle caused by inaccurate sensor feedback\u003c\/li\u003e\n\u003cli\u003eFuel trim issues from a worn upstream sensor\u003c\/li\u003e\n\u003cli\u003eEmissions performance problems tied to sensor response\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes and quality\u003c\/h2\u003e\u003cp\u003eConfirm the connector, thread size, and upstream location before installation. This sensor is specific fit, so it should be matched to the exact listed application rather than used as a universal replacement. NTK states that its oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications.\u003c\/p\u003e","brand":"NTK","offers":[{"title":"Default Title","offer_id":53731449274549,"sku":"BFPZ-27081","price":86.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/NO_27081_Fro.jpg?v=1794297372","url":"https:\/\/www.partcatalog.com\/products\/ntk-27081-air-fuel-ratio-sensor-upstream","provider":"PartCatalog","version":"1.0","type":"link"}
