{"product_id":"pre-cat-bank-2-upstream-oxygen-sensor","title":"Pre-Cat Bank 2 Upstream Oxygen Sensor","description":"The Bosch oxygen sensor is a direct-fit upstream sensor for your vehicle's exhaust system, specifically for bank 2 (cylinders 4-6) located before the catalytic converter. Its primary function is to measure the oxygen content in the exhaust gases. This critical data is then sent to your BMW's DME (Digital Motor Electronics) to precisely adjust fuel trim, thereby optimizing engine performance and fuel economy.\n\nSymptoms of a failing oxygen sensor can manifest in several ways, including a noticeable decrease in fuel efficiency, a failed emissions test, illumination of the check engine light on your dashboard, and overall poor engine drivability.\n\nThis 910mm length oxygen sensor is designed for specific BMW models, including the 325i, 325xi, 330i, 330xi, 525i, 525xi, 530i, 530xi, and Z4, with specific notes regarding production dates (from 11\/2005 for some models) and engine types (3.0L L6 N52 Gas).","brand":"Bosch Pre-Cat","offers":[{"title":"Default Title","offer_id":52687230665016,"sku":"0258017099","price":107.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662155508.jpg?v=1784881660","url":"https:\/\/store.motormia.co\/products\/pre-cat-bank-2-upstream-oxygen-sensor","provider":"MOTORMIA","version":"1.0","type":"link"}
