Cometic MLS (Multi-Layer Steel) Head Gaskets are engineered to provide maximum sealing performance for high-output 5SFE engines without the need for additional sealants. Constructed from multiple layers of embossed stainless steel, these gaskets offer superior rebound and corrosion resistance. This design is ideal for maintaining a reliable seal between aluminum heads and either aluminum or cast iron blocks, effectively managing the shearing forces created by different thermal expansion rates.

The outer layers are coated with Viton, a high-performance fluoroelastomer capable of withstanding temperatures up to 250°C (482°F). This coating ensures a tight seal across a variety of surface finishes and load conditions. The internal stainless steel shim layer allows for precise thickness control while reducing bore distortion by requiring less clamp load than traditional gaskets.

• Manufacturer Part Number: C4315-040
• Bore Size: 88mm
• Compressed Thickness: 0.040"
• Material: Multi-Layer Steel (MLS) with Viton coating
• Heat resistant up to 250°C / 482°F
• Promotes even load distribution across the sealing surface

Fits select 1988-1994 Toyota Celica and MR2 Turbo models equipped with the 3S-GE or 3S-GTE engine. This Cometic Multi-Layer Steel (MLS) head gasket is engineered to provide the superior sealing performance required for high-output turbocharged and naturally aspirated builds.

Constructed from multiple layers of embossed stainless steel, this gasket features outer layers coated with Viton, a fluoroelastomer rubber-based material capable of withstanding temperatures up to 250°C (482°F). The MLS design is specifically effective at managing the shearing forces created between aluminum cylinder heads and cast iron or aluminum blocks. Unlike composite gaskets, the Cometic MLS requires no additional sealants and conforms to the sealing surface while requiring less clamp load, which helps minimize cylinder bore distortion.

• Bore Size: 87mm
• Compressed Thickness: .060 inch (1.5mm)
• Material: Multi-Layer Stainless Steel (MLS) with Viton coating
• Heat Resistance: Rated to 482°F (250°C)
• Manufacturer Part Number: C4314-060

The uncoated stainless steel center shim allows for precise thickness variations to meet specific engine requirements. This gasket is an ideal choice for both street performance and competitive racing applications where head-to-block integrity is critical.
