What is the material of these cylinder head bolts?

These MAHLE Original cylinder head bolts are made from high-strength steel. This material is chosen to withstand the significant clamping forces and heat generated within the engine.

Do I need to replace all the head bolts when installing a new cylinder head?

Yes, it is standard practice and highly recommended to replace all cylinder head bolts whenever the cylinder head is removed. This ensures consistent clamping force and prevents potential issues from old, stretched, or weakened fasteners.

What torque specifications should I use for these bolts?

Always refer to the specific service manual or manufacturer's installation instructions for your BMW model and year. Proper torque sequence and values are critical for achieving a correct cylinder head seal.

Product Details

These MAHLE Original cylinder head bolts are made from high-strength steel, ensuring they can handle the clamping forces needed to keep your engine's cylinder head sealed tight. If you're rebuilding the top end of your BMW, whether it's a 1992-1995 325i, a 1996-2000 328i, or a 1991-1995 525i, using the right fasteners is critical for proper engine function and longevity.

When you're putting a cylinder head back onto the engine block, these bolts are designed to provide consistent clamping force across the entire head. This is important because it helps prevent leaks from the combustion chambers, oil passages, and coolant jackets. The high-strength steel construction means they won't stretch or fail under the heat and pressure inside your engine, giving you peace of mind after the job is done.

This kit includes all the necessary bolts to properly secure your cylinder head. Always refer to the manufacturer's installation instructions for correct torque sequences and specifications to ensure a reliable seal.
