The Cometic C4166-051 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for Toyota 4A-GE and 4A-GEZ 16-valve engines. This precision gasket features an 83mm bore diameter and .051-inch compressed thickness, providing optimal sealing and combustion chamber volume for performance applications.

Key Features:

• Multi-layer steel construction for superior durability and heat resistance
• 83mm bore diameter designed for Toyota 4A-GE/4A-GEZ engines
• .051-inch (1.30mm) compressed thickness
• Precision-engineered for 16-valve cylinder head configurations
• MLS technology provides enhanced sealing under extreme cylinder pressures
• Compatible with both stock and performance builds

Cometic MLS gaskets use multiple layers of stainless steel with a Viton rubber coating to maintain compression seal integrity in high-performance and racing applications. The .051-inch thickness allows for precise compression ratio tuning when building or rebuilding Toyota 4A-GE engines commonly found in AE86 Corolla, MR2, and other performance platforms.
