Tubes are produced on a 7 axis CNC mandrel bender for exceptional roundness and consistency, reducing turbulence and stress at the welds.\n  \u003c\/p\u003e\n  \u003cp\u003e\n    At the turbo outlet, temperatures can exceed 800 to 1100 degrees Celsius, so overlapping and cross welding techniques are used for superior strength. Precision robotic spot welding ensures deep penetration and leak-free joints for long service life.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eFitment\u003c\/h3\u003e\n  \u003cp\u003e\u003cstrong\u003eEngine:\u003c\/strong\u003e BMW N26 2.0 turbo petrol\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eChassis:\u003c\/strong\u003e BMW 5 Series\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eF10 520i and 528i including xDrive 2010 to 2013\u003c\/li\u003e\n    \u003cli\u003eF10 LCI 520i and 528i including xDrive 2012 to 2016\u003c\/li\u003e\n    \u003cli\u003eF11 520i and 528i including xDrive 2012 to 2013\u003c\/li\u003e\n    \u003cli\u003eF11 LCI 520i and 528i including xDrive 2013 to 2017\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003ePart number\u003c\/h3\u003e\n  \u003cp\u003e\u003cstrong\u003eA206NE\u003c\/strong\u003e\u003c\/p\u003e\n\n  \u003ch3\u003eInstallation\u003c\/h3\u003e\n  \u003cp\u003e\n    Direct replacement using factory hardware.
