• Volkswagen engines that employ the same head gasket specification.
• Other European OEMs that require a high‑quality seal for their cylinder heads.

Installation Guidelines

1. Preparation: Clean all mating surfaces thoroughly to remove oil, coolant, and debris. Inspect the head and block for damage or warping.
2. Alignment: Position the gasket carefully, ensuring that it sits flush against both the cylinder head and block.
3. Tightening Sequence: Follow the manufacturer’s torque sequence to avoid over‑tightening or under‑tightening. Use a calibrated torque wrench for accuracy.
4. Final Check: After installation, verify that all fasteners are secure and that there is no visible gap in the gasket profile.
