Cometic C4117-120 MLS Cylinder Head Gasket Bore Thickness - 75.5mm 120

The Cometic C4117-120 is a Multi-Layer Steel (MLS) cylinder head gasket engineered for Honda D-series engines. This gasket features a 75.5mm bore diameter and .120" (3.05mm) compressed thickness, making it ideal for performance builds and engines requiring enhanced sealing capabilities.

Key Features:

• Multi-Layer Steel construction provides superior sealing and durability under high-cylinder pressures
• 75.5mm bore diameter accommodates stock and mild overbore applications
• .120" compressed thickness helps achieve optimal compression ratios for performance applications
• Advanced coating technology ensures consistent clamping force and improved combustion sealing
• Designed for Honda D15B1, D15B2, D15B6, D15B7, D15B8, and D16A6 engine applications
• Manufactured to exacting tolerances for precise fitment and reliable performance

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, creating a gasket that maintains its sealing integrity even under extreme temperatures and pressures. The proprietary coating on each layer provides micro-sealing while allowing the gasket to adapt to minor surface imperfections. This gasket is suitable for naturally aspirated, turbocharged, and supercharged applications when proper surface preparation and installation procedures are followed.
