{"product_id":"bmw-o-ring-5","title":"Original BMW Crankcase Breather O-Ring 42.86 x 3.53 mm for BMW 2, 3, 4, 5 Series, X1, X3, X4, X5, and Z4 (2012–2018)","description":"\u003cp\u003eThis Original BMW O-ring seals the crankcase breather on the N20 and N26 four-cylinder engines in the 228i, 320i, 328i, 428i, 528i, X1, X3, X4, X5 xDrive40e, and Z4 sDrive28i (2012–2018). BMW sizes the ring at 42.86 x 3.53 mm, and it weighs only 2 g (0.07 oz). The crankcase ventilation system sends blow-by gases from the crankcase back into the intake manifold so they burn in the combustion process. This ring keeps that connection sealed. BMW shows production of this number starting in March 2011. It is made in China and sold individually.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eAn O-ring seals by compressing in its groove between two mating parts, which is why the size has to be exact. BMW uses this one ring across the N20 and the N26, the variant fitted to some 228i, 328i, and 428i models. Rear-drive and xDrive cars share it, as do sedans, the 3 Series Gran Turismo, the 4 Series coupe and Gran Coupe, and the four-cylinder X models. The ventilation system also controls how much blow-by escapes the combustion chamber and helps hold crankcase pressure in check. A sound seal at each joint keeps that system working as BMW intended.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Original BMW)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-12-7-605-329\u003c\/li\u003e\n\u003cli\u003eBMW part name: O-ring\u003c\/li\u003e\n\u003cli\u003eSize: 42.86 x 3.53 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 2 g (0.07 oz)\u003c\/li\u003e\n\u003cli\u003eApplication: engine crankcase breather\u003c\/li\u003e\n\u003cli\u003eEngines: N20 and N26 four-cylinder\u003c\/li\u003e\n\u003cli\u003eProduction start: March 2011\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: China\u003c\/li\u003e\n\u003cli\u003eSold as: one O-ring\u003c\/li\u003e\n\u003cli\u003eWarranty: 24-month Original BMW parts warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhich engines use this O-ring?\u003c\/strong\u003e\u003cbr\u003eBMW uses it on the N20 and N26 four-cylinder engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it fit every X5?\u003c\/strong\u003e\u003cbr\u003eNo. Among X5 models it is matched only to the xDrive40e plug-in hybrid from 2016–2018, which uses the N20.\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck the table below for the exact year, model, submodel, and any listed notes.
