Cometic C4540-051 MLS Cylinder Head Gasket for Renault F7P/F7R 84mm Bore

The Cometic C4540-051 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Renault F7P and F7R engines. This high-performance gasket features an 84mm bore diameter and a compressed thickness of 0.051 inches, providing exceptional sealing performance for both stock and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 84mm bore diameter engineered for Renault F7P/F7R engine platforms
• 0.051-inch compressed thickness for precise compression ratio tuning
• Advanced embossment technology ensures optimal sealing under extreme pressures
• Viton rubber coating on outer layers provides enhanced sealing properties
• Accommodates thermal expansion and cylinder head movement better than traditional composite gaskets
• Reusable design allows for engine disassembly and reassembly when needed

Cometic MLS gaskets are the preferred choice for high-performance and racing applications due to their ability to withstand extreme cylinder pressures and temperatures. The multi-layer construction consists of multiple layers of stainless steel with strategically placed embossments that provide the optimal amount of recoverable spring force to ensure a superior seal throughout the engine's operating range.

This gasket is ideal for engine builders looking to fine-tune compression ratios or anyone seeking a premium replacement gasket that exceeds OEM specifications. The MLS design is especially beneficial for turbocharged or high-compression naturally aspirated builds where head gasket failure is a common concern.
