Victor Reinz 14-32315-01 Engine Cylinder Head Bolt Set

BMW Cylinder Head Bolt Set

Victor Reinz 14-32315-01 is an engine cylinder head bolt set for late-model BMW applications that use torque-to-yield head bolts. When servicing the cylinder head, replacing these fasteners is the correct approach because TTY bolts are engineered to stretch during tightening and should not be reused.

• Designed for torque-to-yield head bolt replacement during head gasket service
• Supports proper cylinder head clamping force after disassembly
• Direct-fit service part for select BMW 128i, 328i, 530i, X3, Z4, and related models

Installation Notes

Replace the original head bolts any time the cylinder head is removed on a TTY-equipped engine. Follow the BMW service procedure for tightening sequence, torque stages, and angle specifications, and verify engine code and model-year fitment before installation. Confirm the application against the vehicle’s engine designation, especially on BMW 530i, 528i, and X3 variants.
