BMW X5 X6 G05 G06 Engine

Upgrade or replace your luxury performance SUV’s heart with this OEM B58C RWD Long Block Engine, directly sourced from a 2020 BMW X5 (VIN: 5UXCR4C06L9C49782). Engineered for power and refinement, this B58 3.0L inline-6 twin-scroll turbocharged motor is factory-designed for the G05 X5 and G06 X6 platforms.

This specific long block includes the rare 2-Port Cylinder Head variant of the B58C, known for improved combustion efficiency and reduced emissions. Sold as a core with a 90-day warranty, this engine is ideal for rebuilds or performance swaps. The engine turns freely and shows no cracks in the cylinder block or head. It did show signs of water presence in the turbo oil line, though no water contamination was detected in the engine oil during inspection.

Compression test results vary by cylinder, with some reading below optimal levels—indicating this is a core motor ready for servicing or rebuilding. All used components are provided for installation convenience and are not guaranteed.

Whether you’re restoring a factory BMW setup or looking to build a performance B58C platform, this OEM long block offers authentic BMW engineering and a foundation you can build on.
