{"product_id":"crankcase-breather-hose","title":"Crankcase Breather Hose","description":"The Rein Crankcase Breather Hose is a vital part of your vehicle's positive crankcase ventilation (PCV) system, designed as a direct OE-quality replacement. Manufactured in France, this hose effectively channels pressurized air and oil vapors from the engine crankcase to the air\/oil separator (PCV valve). The PCV system captures oil vapors, allowing them to return to the engine, while cleansed air is fed back into the engine for combustion, aiding in both performance and emissions control.\n\nOver time, the engine crankcase breather hose can degrade due to constant exposure to heat, oil vapors, and pressure. Common failure symptoms include cracking, breaking, or developing leaks, which can lead to unmetered air entering the intake system. This can trigger a Check Engine Light with codes related to air intake leaks or airflow issues. Additionally, a compromised hose can cause rough running, engine misfires, and visible oil residue on or around the hose and adjacent engine components. A cracked or broken connector can also occur due to material brittleness over time.\n\nRein Automotive is known for its OE-quality replacement parts, aiming to be a true dealer alternative. The brand focuses on parts that meet or exceed original equipment standards, sometimes addressing known weaknesses in factory components. This commitment to quality is backed by ISO 9001:2015 certification.\n\nThis specific Rein Crankcase Breather Hose is designed to fit various BMW models, including the 328i, 328i xDrive, 528i, X3, X5, and Z4, across multiple model years. Please ensure compatibility with your specific vehicle configuration.","brand":"BMW \/","offers":[{"title":"Default Title","offer_id":52687213265208,"sku":"W0133-1850537","price":37.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660681197.jpg?v=1784881450","url":"https:\/\/store.motormia.co\/products\/crankcase-breather-hose","provider":"MOTORMIA","version":"1.0","type":"link"}
