81.5mm MLX Head Gasket .034 Toyota 2010-2021

The 81.5mm MLX Head Gasket .034 for Toyota 2010–2021 is a precision-engineered cylinder head seal designed for builders and mechanics who demand reliable compression retention and leak-free operation in modified and stock engine builds. This Cometic gasket addresses a critical sealing challenge: maintaining consistent clamping load across the combustion chamber while accommodating modern fuel systems and boost applications.

Cometic's MLX gasket material features a multi-layer steel construction with a .034-inch thickness, optimized to handle elevated combustion pressures while resisting blow-by and coolant seepage. The 81.5mm bore diameter matches Toyota's factory specifications precisely, ensuring accurate bore-to-gasket concentricity and eliminating weak sealing zones around cylinder walls. This thickness specification provides the ideal balance between clamp load distribution and gasket conformability on machined or resurfaced cylinder heads.

This gasket fits Toyota models from 2010 through 2021, making it an excellent choice for those rebuilding naturally aspirated or turbocharged engines. The MLX facing resists chemical degradation from modern coolants and helps prevent gasket creep during thermal cycling, essential when cylinder head temperatures fluctuate between idle and sustained load.
