As part of the NGK family, NTK applies ceramic sensor manufacturing expertise and OE-oriented engineering to deliver fit and function that align with original equipment requirements. This oxygen sensor is a strong match for Saab 9-3, Saab 900, Saab 9000, and Porsche 911 applications listed in the fitment data, including upstream locations where precise air-fuel monitoring is required. The NTK 25582 is built for direct replacement service and is cross-referenced to Bosch 13662 and DENSO 234-4185 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFaulty oxygen sensor readings\u003c\/li\u003e\n\u003cli\u003eDelayed closed-loop fuel control\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to sensor performance\u003c\/li\u003e\n\u003cli\u003eAir-fuel ratio feedback issues at the upstream location\u003c\/li\u003e\n\u003cli\u003eDriveability problems caused by inaccurate exhaust oxygen measurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the connector, harness length, thread diameter, and upstream position before installation. Confirm the vehicle application against the listed fitment data for Saab 9-3, Saab 900, Saab 9000, or Porsche 911. Use the part number 25582 to match the correct sensor configuration, and compare the existing sensor’s wire count and mounting style before replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eNTK tests these oxygen sensors during manufacturing to support quality and reliability that meet or exceed OE specifications. The brand is recognized as a major original equipment oxygen sensor supplier, and the 25582 reflects that OE-focused approach.\u003c\/p\u003e","brand":"NTK","offers":[{"title":"Default Title","offer_id":53731438690485,"sku":"BFPZ-25582","price":100.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/NO_25582_Fro.jpg?v=1794296388","url":"https:\/\/www.partcatalog.com\/products\/ntk-25582-oxygen-sensor-upstream","provider":"PartCatalog","version":"1.0","type":"link"}
