BMW cylinder head bolts are almost always stretch bolts and should never be reused after removal. Reusing old bolts can lead to a weak seal between the cylinder head and engine block, allowing the head to lift and cause potentially catastrophic damage. Replace your old cylinder head bolts with these brand new Elring bolts to ensure your head is properly secured to prevent damage and keep your engine healthy. Replaces BMW # 11128513128
