<p>This genuine BMW Lower Turbo / Turbocharger Mount / Heat Shield (OEM #8600300) is a used part removed from a donor vehicle. It serves as both a support bracket and thermal barrier for the right-side turbocharger on 4.4L V8 turbocharged engines (N63/S63 family). Over time, the factory heat shield can become brittle or the mount loosen, leading to rattling or increased underhood heat exposure. This component helps secure the turbo while deflecting radiant heat away from nearby wiring and hoses.</p><p><strong>Fits:</strong> BMW 750i (2016-2019), BMW 750i xDrive (2016-2022), BMW Alpina B7 (2017-2022), BMW Alpina B8 Gran Coupe (2022-2025), BMW Alpina XB7 (2021-2022), BMW M550i xDrive (2018-2023), BMW M850i xDrive (2019-2026), BMW M850i xDrive Gran Coupe (2020-2026), BMW X5 (2019-2023), BMW X6 (2020-2023), BMW X7 (2019-2023)</p><p><strong>OEM part number:</strong> 8600300. <strong>Also replaces / interchanges with:</strong> 11658600300.</p><p><strong>Condition:</strong> Used OEM, pulled in-house from a donor vehicle scanned with factory diagnostic tools; tested where possible, with per-part condition notes. 30-day returns.</p>
