The Cometic Toyota 1UZ-FE (Non VVT-i) 89mm Bore .051in LHS MLS Head Gasket (SKU: C14151-051, UPC: 191070573058), engineered to deliver unmatched sealing strength, durability, and reliability for high-performance builds. Designed specifically for the Toyota/Lexus 1UZ-FE 4.0L V8 DOHC 32v engine (1989-1998), this Multi-Layer Steel (MLS) head gasket is the top choice for enthusiasts and professionals seeking superior performance over all other options. Whether you’re rebuilding a classic Lexus or boosting horsepower in a performance application, this gasket ensures your engine operates at its peak, preventing costly failures and maximizing output.
Why Cometic?
The Cometic MLS Head Gasket stands out as the best choice for your Toyota 1UZ-FE engine due to its cutting-edge design and premium materials:
Sealing Performance: Constructed from multiple layers of embossed stainless steel, this gasket provides exceptional sealing for high-output engines, eliminating the need for sealants and ensuring a leak-free seal under extreme conditions.
Viton Coating for Durability: The outer layers are coated with Viton, a high-temperature, chemical-resistant fluoroelastomer (up to 250°C/482°F), designed to withstand harsh environments, resist corrosion, and maintain integrity under high cylinder pressures.
Optimized for High Horsepower: Perfect for performance builds, this gasket handles increased horsepower and cylinder pressures, making it ideal for turbocharged, supercharged, or naturally aspirated 1UZ-FE engines.
Reduced Bore Distortion: The MLS design requires less clamp load, minimizing bore distortion and ensuring long-term reliability, even with aluminum heads on aluminum or cast iron blocks.
Proudly Made in the USA: Manufactured in Cometic’s state-of-the-art 70,000 sq.ft. facility in Concord, Ohio, using American-sourced materials for uncompromising quality.
No other head gasket matches the Cometic MLS’s combination of strength, resilience, and precision, making it the ultimate choice for your 1UZ-FE engine rebuild or upgrade.
