Cometic MLS Head Gasket .034" | Ford Focus ST 2013-2018

The Cometic MLS Head Gasket .034" is engineered for the Ford Focus ST 2013–2018 platform and is intended for applications where a slightly increased head gasket thickness is required. This multi-layer steel head gasket provides a controlled sealing surface while accommodating changes in engine geometry that may result from machining or performance-oriented engine builds. The .034 inch compressed thickness allows for subtle adjustment to compression ratio and piston-to-head clearance without major changes to engine architecture.

Multi-Layer Steel Design

This gasket utilizes a multi-layer steel construction made up of embossed stainless steel layers combined with a specialized surface coating. The layered structure allows the gasket to maintain a consistent seal under varying thermal and mechanical loads. The coating enhances micro-sealing around combustion chambers, oil passages, and coolant ports.

• Multi-layer steel construction for uniform clamping force
• Stainless steel layers resist heat cycling and corrosion
• Designed to manage elevated cylinder pressures

.034 Inch Thickness Characteristics

The .034 inch compressed thickness is commonly selected for engines that have undergone cylinder head or block machining, or for builds requiring a minor reduction in compression ratio. This thickness helps maintain proper clearances while preserving overall engine reliability.

• .034 inch compressed thickness
• Provides additional piston-to-head clearance
• Useful for mildly modified or refreshed engines

Application and Material Considerations

The Cometic MLS Head Gasket .034" is suitable for both street-driven and performance-focused Ford Focus ST applications. Precision manufacturing ensures consistent fitment, while the materials are selected to support long-term durability when paired with appropriate surface finishes and fasteners.

• Designed specifically for Ford Focus ST 2013–2018 engines
• Precision-cut for accurate alignment
• MLS construction supports stable, long-term sealing

Note: This head gasket features a thicker-than-stock profile and may alter engine compression characteristics compared to factory specifications.
