MAHLE Original Scion Xa 06-04 Cylinder Head Bolts

These Victor Reinz cylinder head bolts are made from high-strength steel, meaning they can handle the clamping forces needed to keep your engine's cylinder head sealed tight. When you're rebuilding the top end of an engine, like on a Scion xA, Toyota Echo, or Prius, using the correct head bolts is crucial for preventing leaks and ensuring proper compression. These bolts are designed to meet the original equipment specifications for clamping force and stretch, so you can be confident they'll perform as expected.

Using new head bolts is always recommended when removing the cylinder head, as they are torque-to-yield fasteners. This means they are designed to stretch to a specific point during installation to achieve the correct clamping load. Reusing old bolts can lead to improper torque, which can cause gasket failure and serious engine damage. Victor Reinz is a well-known name in engine components, and this set is a solid option for your engine repair.
