The 95.8mm MLX Head Gasket LH .036 for Subaru FB25D is a precision-engineered cylinder head gasket designed for builders and mechanics working on naturally aspirated and turbocharged flat-four engines. This gasket is essential for anyone rebuilding or upgrading a Subaru FB25D powerplant, whether you're restoring stock reliability or preparing an engine for performance modifications.
Cometic Gaskets manufactures this component to exacting tolerances, making it the preferred choice for professional shops and serious enthusiasts who demand leak-free sealing under boost and sustained rpm loads. The .036-inch thickness and MLX construction deliver superior clamping force retention and gasket creep resistance compared to OEM paper gaskets, critical when running elevated compression ratios or turbocharger pressure.
The 95.8mm bore dimension ensures precise fitment to your FB25D's cylinder head and block surface, preventing blow-by and coolant seepage that can compromise engine longevity and performance tuning gains. Installation on FB25D engines—found in Subaru Outback, Legacy, and Forester models—requires careful surface preparation, proper torque sequencing, and use of quality fasteners to achieve lasting results.
