Cometic C4166-120 MLS Cylinder Head Gasket Bore Toyota - 83mm 4A-GE 16-Valve

The Cometic C4166-120 is a multi-layer steel (MLS) cylinder head gasket engineered for the Toyota 4A-GE and 4A-GEZ 16-valve engines, featuring a compressed thickness of 0.120 inches with an 83mm bore and 3-layer construction. This precision-manufactured gasket delivers superior sealing performance for high-output engine applications.

Key Features:

• Multiple layers of stainless steel construction provide increased strength, rebound capability, and corrosion resistance
• Outer layers are embossed and coated with Viton, a fluoroelastomer rubber material heat resistant to 482°F (250°C)
• Center shim layer is uncoated stainless steel that can be varied to accommodate thickness requirements
• Requires no sealants and is ideal for both aluminum-to-aluminum and aluminum-to-cast iron block configurations
• Capable of withstanding the shearing forces created between dissimilar materials

The Viton coating is engineered to meet the demands of harsh sealing environments, varying load conditions, and different surface finishes, making this gasket an excellent choice for both stock rebuilds and performance applications on Toyota 4A-GE engines.
