Cometic C4557-027 Toyota MLS Cylinder Head Gasket Bore - 1GR-FE 95.5mm

The Cometic C4557-027 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Toyota 1GR-FE engines with single VVT-i configuration. This high-performance gasket features a 95.5mm bore diameter and .027" (0.027 inch) compressed thickness, making it ideal for stock replacement or performance builds requiring reliable sealing under extreme conditions.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 95.5mm bore diameter precisely matched to 1GR-FE cylinder dimensions
• .027" compressed gasket thickness for proper compression ratio
• Engineered for single VVT-i equipped 1GR-FE engines (right-hand side application)
• Exceeds OEM specifications for temperature and pressure resistance
• Embossed stainless steel layers with proprietary coatings prevent leaks

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that rebounds and reseals minor imperfections in sealing surfaces. This design accommodates thermal expansion and cylinder pressure fluctuations better than traditional composite gaskets, making it the preferred choice for both stock rebuilds and performance applications. Compatible with Toyota 1GR-FE engines found in 4Runner, FJ Cruiser, Tacoma, and Tundra models equipped with single VVT-i.
