The Cometic MLS Head Gasket for the 1991 and up Lexus LS400 4.0L 1UZ-FE is a high-performance sealing component designed to withstand the demanding conditions of modern engines. Constructed with three layers of stainless steel, this gasket offers enhanced strength, excellent rebound properties, and superior corrosion resistance. The outer layers are embossed and coated with a Viton rubber-based material, which provides exceptional heat resistance up to 2500°C (4820°F). This design ensures reliable sealing under high pressure and temperature environments, making it suitable for both stock and modified applications. The gasket’s precise bore size of 82.5mm ensures a perfect fit, maintaining optimal compression and engine integrity.

This gasket is intended for use in Lexus LS400 models from 1991 onward, equipped with the 4.0L 1UZ-FE engine. It serves as a direct replacement for the factory gasket, offering improved durability and sealing performance. The gasket is suitable for street, performance, and racing applications where high-temperature sealing is critical. Installation involves standard head gasket replacement procedures, and the kit includes the gasket itself with no additional components. Proper fitment and material quality make this gasket an ideal upgrade for maintaining engine reliability and performance in demanding driving conditions.

Overview

The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.

The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
