NTK is known for oxygen sensor manufacturing and uses ceramic technology control from raw material through finished production. This sensor is engineered for Subaru Forester, Subaru Impreza, and Subaru Legacy applications listed below, with downstream coverage for 1998 Forester and 1995-1998 Impreza and Legacy, plus upstream coverage for 1995-1997 Impreza and 1995 Legacy. This part cross-references DENSO Auto Parts 234-3088 and Delphi ES10439 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFaulty oxygen sensor signal output.\u003c\/li\u003e\n\u003cli\u003eDelayed sensor response after warm-up.\u003c\/li\u003e\n\u003cli\u003eCheck engine light conditions related to oxygen sensor performance.\u003c\/li\u003e\n\u003cli\u003eIncorrect air-fuel feedback in the exhaust system.\u003c\/li\u003e\n\u003cli\u003eReplacement needs for a worn threaded sensor assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Quality\u003c\/h2\u003e\u003cp\u003eVerify the sensor position, thread size, wire count, and harness length before installation. Use the listed fitment to confirm whether the application is downstream or upstream for your Subaru Forester, Impreza, or Legacy. NTK states that these oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications.\u003c\/p\u003e","brand":"NTK","offers":[{"title":"Default Title","offer_id":53519176827061,"sku":"BFPZ-24520","price":79.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/NO_24520_Fro.jpg?v=1791954216","url":"https:\/\/www.partcatalog.com\/products\/ntk-24520-oxygen-sensor-downstream-or-upstream","provider":"PartCatalog","version":"1.0","type":"link"}
