Special stud bolt kit from ARP and BAR-TEK® Motorsport for the cylinder head for your BMW 3.0L 24V (N55) as used in the 235i, 335i, 435i and many more.
We are using 11 mm bolts here. The thread must therefore be enlarged. This is the only way to ensure that the bolts can easily withstand boost pressure beyond 2 bar.
High-performance bolts are made of high-strength and heat-treated 8740 chromium molybdenum forged steel and are therefore ideally suited for use in racing engines.
fastening torque 122 Nm
