This is a genuine BMW Cylinder Head Bolt, part number 11128512674, engineered to meet the exact specifications of your BMW engine. Properly torqued cylinder head bolts are crucial for maintaining the seal between the cylinder head and the engine block.

Crafted from high-quality materials, this bolt offers superior strength and resistance to stretching and fatigue under extreme engine temperatures and pressures. Replacing worn or damaged bolts with genuine parts ensures the longevity and reliability of your engine.
