Cometic MLS Head Gasket .066" | Ford Focus ST 2013-2018

The Cometic MLS Head Gasket .066" is designed for the Ford Focus ST 2013–2018 engine platform and is intended for applications requiring a significantly increased head gasket thickness. This multi-layer steel head gasket is commonly selected for engines with extensive machining or configurations that demand maximum piston-to-head clearance. The .066 inch compressed thickness represents one of the thickest options available for this application while maintaining consistent sealing across combustion, oil, and coolant passages.

Multi-Layer Steel Construction

This head gasket features a multi-layer steel design made from embossed stainless steel layers combined with a specialized sealing coating. The independent movement between layers allows the gasket to accommodate thermal expansion and contraction during repeated heat cycles. The surface coating promotes micro-sealing at critical interfaces to help maintain sealing integrity under varying operating conditions.

• MLS construction for even clamping force distribution
• Stainless steel layers resist corrosion and fatigue
• Designed to support high cylinder pressures

.066 Inch Thickness Characteristics

With a compressed thickness of .066 inches, this gasket is typically used in engines that require substantial clearance adjustments due to block decking, cylinder head resurfacing, or specialized compression ratio management. The increased thickness provides a notable change from stock specifications while maintaining reliable sealing performance.

• .066 inch compressed thickness
• Maximizes piston-to-head clearance
• Can significantly reduce compression ratio compared to thinner options

Application and Material Benefits

The Cometic MLS Head Gasket .066" is suitable for Ford Focus ST engines used in demanding street or performance-focused environments where precise fitment and durable sealing are required. Precision manufacturing ensures accurate alignment with factory bore spacing and fluid passages when paired with compatible components and surface finishes.

• Designed for Ford Focus ST 2013–2018 engines
• Precision-cut for consistent alignment
• Multi-layer steel construction supports long-term sealing stability

Note: This head gasket features a substantially thicker-than-stock profile and will alter engine compression and geometry relative to factory specifications.
