The Cometic C10171 is a complete engine gasket kit engineered for high-performance and competition engine builds. Cometic is a globally recognized leader in precision sealing solutions, trusted by professional engine builders and racing teams across automotive, V-twin, powersports, and marine applications.

This kit features Cometic's proven Multi-Layer Steel (MLS) head gasket technology at its core — constructed from multiple embossed layers of proprietary high-temperature coated and uncoated stainless steel for superior sealing integrity under extreme heat and pressure. Supporting gaskets throughout the kit utilize application-matched materials including Spring Steel (SPS) and high-temp Viton coatings, selected to deliver the best possible seal at each individual sealing surface.

Key Features:

• MLS (Multi-Layer Steel) cylinder head gasket for superior combustion sealing under high heat and cylinder pressure
• Application-matched materials throughout — each gasket uses the optimal compound for its sealing surface
• Viton-coated steel gaskets on critical surfaces like rocker boxes and cylinder bases virtually eliminate leakage between metal surfaces
• Engineered to precise OEM tolerances for accurate fit and leak-free installation
• Suitable for engine rebuilds, performance builds, and competition applications
• No messy gasket sealers or silicone required for most sealing surfaces

The C10171 provides a comprehensive sealing solution that eliminates the guesswork of sourcing individual gaskets. Whether tackling a routine engine rebuild or assembling a high-output performance build, this kit delivers the consistent, long-lasting sealing performance Cometic is known for worldwide.
