The Cometic Multi-Layer Steel (MLS) head gasket is engineered to provide maximum sealing performance for high-output engines without the need for additional sealants. Constructed from multiple layers of embossed stainless steel, this gasket handles the high shearing forces generated by differing expansion rates in aluminum-to-iron or aluminum-to-aluminum head and block combinations. The stainless steel construction provides superior rebound properties and resists corrosion in harsh environments.

The outer layers are finished with a Viton rubber coating—a fluoroelastomer heat-resistant to 250°C (482°F)—designed to conform to various surface finishes and maintain a reliable seal under extreme load conditions. The multi-layer design also allows for a reduction in required clamp load, which helps prevent cylinder bore distortion.

• Bore Diameter: 90mm
• Compressed Thickness: 0.051 inch
• Material: Embossed Stainless Steel with Viton coating
• Engine Compatibility: KA24DE
• Manufacturer Part Number: C4285-051

Fits select 1991-2004 Nissan 240SX, Frontier, and Xterra models with the KA24DE engine.

The Cometic MLS (Multi-Layer Steel) Head Gasket is engineered for maximum sealing performance in high-output engines. Constructed from multiple layers of embossed stainless steel, this gasket offers superior rebound and corrosion resistance. The outer layers are finished with a Viton rubber coating, a heat-resistant fluoroelastomer designed to withstand temperatures up to 250°C (482°F). This specialized coating ensures a reliable seal across various surface finishes and load conditions without the need for additional sealants.

Designed to handle the shearing forces between aluminum heads and cast iron or aluminum blocks, this gasket uses a reduced clamp load to minimize bore distortion while maintaining even distribution across the sealing area. The uncoated stainless steel shim layer provides precise thickness for consistent compression ratios and engine geometry.

• Manufacturer Part Number: C4285-040
• Bore Size: 90mm
• Compressed Thickness: 0.040"
• Construction: Multi-Layer Steel (MLS)
• Finish: Viton-coated outer layers
• Temperature Rating: Up to 250°C (482°F)

Fits 1987-1992 Toyota Supra and Cressida (7M-GE / 7M-GTE).

The Cometic Multi-Layer Steel (MLS) head gasket provides superior sealing performance for high-output Toyota 7M engines. Engineered to withstand the shearing forces inherent in aluminum-head-to-cast-iron-block configurations, this gasket utilizes multiple layers of embossed stainless steel to maintain a consistent seal under extreme cylinder pressures. Its rebound characteristics allow it to resist corrosion and adapt to thermal expansion during heavy use.

The outer layers are coated on both sides with Viton, a heat-resistant fluoroelastomer capable of withstanding temperatures up to 250°C (482°F). This specialized coating ensures a reliable seal across various surface finishes and load conditions without the need for additional sealants. The center shim layer is constructed from uncoated stainless steel, precisely manufactured to achieve the 0.075" compressed thickness required for your build.
