Cometic MLS Head Gasket .030" (Stock Thickness) | Ford Focus ST 2013-2018
The Cometic MLS Head Gasket .030" (Stock Thickness) is designed for the Ford Focus ST 2013–2018 platform and is engineered to provide consistent sealing under a wide range of operating conditions. This multi-layer steel head gasket matches the factory .030 inch compressed thickness, maintaining original engine geometry, compression characteristics, and timing relationships. It is commonly selected for engines that retain stock dimensions while requiring improved durability over conventional composite gasket designs.
Multi-Layer Steel Construction
This head gasket uses a multi-layer steel design that combines embossed stainless steel layers with specialized sealing coatings. The layered structure allows controlled movement between layers, which helps accommodate thermal expansion and contraction during repeated heat cycles. The outer coating promotes micro-sealing around combustion chambers, coolant passages, and oil galleries.
- MLS design for consistent clamping load distribution
- Stainless steel layers resist corrosion and fatigue
- Engineered to manage high cylinder pressures
Stock Thickness Specification
With a compressed thickness of .030 inches, this gasket mirrors the original equipment specification for the Focus ST engine. Maintaining stock thickness helps preserve factory piston-to-head clearance and combustion chamber volume, which is critical for engines that are refreshed or resealed without changes to internal components.
- .030 inch compressed thickness
- Maintains factory compression ratio
- Suitable for standard bore applications
Application and Material Benefits
The Cometic MLS Head Gasket .030" (Stock Thickness) is well-suited for daily-driven vehicles as well as performance-oriented builds that require a reliable sealing solution. The materials and construction are intended to support long-term durability when used with proper surface finishes and clamping hardware.
- Designed for Ford Focus ST 2013–2018 engines
- Precision-manufactured for accurate fitment
- Multi-layer steel construction for improved sealing stability
Note: This gasket retains stock thickness and does not alter engine compression or geometry.
