Cometic MLS Head Gasket .040" | Ford Focus ST 2013-2018
The Cometic MLS Head Gasket .040" is designed for the Ford Focus ST 2013–2018 engine platform and is intended for applications that require increased head gasket thickness. This multi-layer steel head gasket provides a reliable sealing surface while allowing additional piston-to-head clearance, which can be beneficial for engines that have been machined or configured for specific performance goals. The .040 inch compressed thickness offers a measurable change compared to stock dimensions while maintaining consistent sealing characteristics.
Multi-Layer Steel Construction
This head gasket is manufactured using multiple embossed stainless steel layers combined with a specialized sealing coating. The MLS construction allows each layer to react independently to thermal expansion and contraction, helping maintain sealing integrity across repeated heat cycles. The outer coating enhances micro-sealing around combustion chambers, oil passages, and coolant ports.
- Multi-layer steel design for uniform clamping force
- Stainless steel layers resist corrosion and fatigue
- Engineered to support elevated cylinder pressures
.040 Inch Thickness Profile
With a compressed thickness of .040 inches, this gasket is commonly selected for engines requiring increased clearance due to block decking, cylinder head resurfacing, or specific compression ratio adjustments. The added thickness helps maintain proper clearances while supporting long-term durability.
- .040 inch compressed thickness
- Provides additional piston-to-head clearance
- May reduce compression ratio compared to stock thickness
Application and Material Benefits
The Cometic MLS Head Gasket .040" is suitable for both street-driven and performance-focused Ford Focus ST applications where precise fitment and consistent sealing are required. Precision manufacturing ensures accurate alignment with factory passages and bores when used with compatible components.
- Designed for Ford Focus ST 2013–2018 engines
- Precision-cut for consistent fitment
- Multi-layer steel construction supports stable sealing over time
Note: This gasket features a thicker-than-stock profile and can alter engine compression and geometry compared to factory specifications.
