BMW N55 Engine Pro-Series 18.8 Cylinder Head Stud Set

Replacing the original cylinder head screws with high-strength Pro-Series 18.8 studs.
This is necessary when making large increases in performance, as the original cylinder head screws elongate during operation and the cylinder head can lift off.
The Pro-Series 18.8 stud bolts with a tensile strength of 1850 N / mm² provide a solution to this.
In addition, these stud bolts do not have to be replaced after dismantling, but can be reused.
