{"product_id":"bmw-breather-hose-4","title":"Original BMW Crankcase Vent Hose for BMW 325, 325e, 325es, and 528e (1982–1987)","description":"\u003cp\u003eThe Original BMW crankcase vent hose, part number 11-15-1-278-804, is the breather line for the M20 six-cylinder in the 1982–1987 BMW 528e, the 1984–1986 BMW 325e, and the 1986 BMW 325 and 325es. BMW calls it a vent hose and supplies it as a single piece weighing 78 grams. Each car uses one. BMW began producing this number in September 1981, so it was in place from the start of E28 528e production through the end of the E30 325e run. A crankcase vent hose carries blow-by gases out of the crankcase so the engine can draw them back into the intake and burn them, rather than letting pressure build inside the block.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eThis hose replaced an earlier BMW number, 11-15-1-276-903. BMW marks the change as exchangeable retrospectively, which means the current hose is the correct replacement on cars that left the factory with the earlier part. The cross-reference numbers 6036 and W01331639009 also point to this same hose, which is useful if you are matching it against an older parts invoice or a box you pulled off the shelf. The same vent hose is shared between the E28 and E30 versions of the M20 engine, so a 528e and a 325e take the identical part.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Original BMW part)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-15-1-278-804\u003c\/li\u003e\n\u003cli\u003eBMW part name: vent hose (crankcase breather hose)\u003c\/li\u003e\n\u003cli\u003eQuantity per car: one\u003c\/li\u003e\n\u003cli\u003eWeight: 78 g (0.2 lb)\u003c\/li\u003e\n\u003cli\u003eProduction start: September 1981\u003c\/li\u003e\n\u003cli\u003eReplaces earlier number 11-15-1-276-903, exchangeable retrospectively\u003c\/li\u003e\n\u003cli\u003eCross-reference numbers: 6036 and W01331639009\u003c\/li\u003e\n\u003cli\u003eSold individually as one hose\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months on Original BMW Parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill this replace hose 11-15-1-276-903?\u003c\/strong\u003e\u003cbr\u003eYes.
