Cometic C15555-047 Ford 3.5L EcoBoost Gen-1 Cylinder Head Gasket .047" MLS 95mm Bore

The Cometic C15555-047 is a high-performance multi-layer steel (MLS) cylinder head gasket engineered specifically for Ford 3.5L Gen-1 EcoBoost engines. This precision-machined gasket features a .047-inch compressed thickness and 95mm bore diameter, designed for the left-hand side (driver side) cylinder head.

Key Features:

• Multi-layer steel construction provides superior sealing and durability under high boost and temperature conditions
• .047-inch (1.19mm) compressed thickness for optimal compression ratio control
• 95mm bore diameter precisely matched to Gen-1 EcoBoost specifications
• Left-hand side (LHS) application for proper cylinder bank fitment
• Advanced coating technology prevents fretting and corrosion while maintaining excellent thermal conductivity
• Engineered to withstand extreme cylinder pressures in turbocharged applications

Cometic MLS head gaskets are the preferred choice for performance builds, engine rebuilds, and forced induction applications where factory gaskets may not provide adequate sealing. The multi-layer design allows the gasket to recover from thermal expansion cycles while maintaining consistent clamping pressure across the entire sealing surface.

Application Note: This gasket is designed for Gen-1 Ford 3.5L EcoBoost engines (2010-2016). Proper surface preparation, torque specifications, and assembly procedures are critical for optimal performance and longevity.
