{"product_id":"bmw-breather-hose-1","title":"Original BMW Crankcase Vent Hose for BMW 2002tii M10 (1971–1974)","description":"\u003cp\u003eOn the fuel-injected BMW 2002tii, this Original BMW vent hose is part of the crankcase ventilation system, routing blow-by gas from the M10 engine's crankcase so it can be burned as part of the intake charge. Pressure that builds inside the crankcase can push past seals and cause them to fail, which is why the ventilation path matters. BMW calls the part a vent hose and shows production starting in January 1970. It weighs 103 grams. This Original BMW hose is made in Switzerland.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eBMW assigns this hose to the 2000tii and 2002tii M10 under the 114 and NK model groups. Breather hoses live with heat, oil vapor, and pressure, so they age, and a cracked, split, or broken hose lets unmetered air into the system. Hoses and valves in this system wear with age and should be replaced when they fail. A genuine BMW part carries the BMW roundel and a short seven-digit part number, here 1252665.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW\u003c\/li\u003e\n\u003cli\u003ePart number: 11-15-1-252-665\u003c\/li\u003e\n\u003cli\u003eBMW part name: vent hose\u003c\/li\u003e\n\u003cli\u003eSystem: crankcase ventilation\u003c\/li\u003e\n\u003cli\u003eEngine: M10, tii fuel injection\u003c\/li\u003e\n\u003cli\u003eWeight: 103 g\u003c\/li\u003e\n\u003cli\u003eProduction from January 1970\u003c\/li\u003e\n\u003cli\u003eMade in Switzerland\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003cli\u003eWarranty: Original BMW Parts carry 24 months of coverage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat happens when this hose cracks?\u003c\/strong\u003e\u003cbr\u003eA cracked or broken breather hose lets unmetered air and oil vapor escape the ventilation path, and it can also lead to leaks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow can I tell this is a genuine BMW part?\u003c\/strong\u003e\u003cbr\u003eGenuine BMW parts carry a BMW roundel stamp and a short seven-digit part number.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCompare your production year and trim against the table below.
