The Cometic Subaru FA20 2.0L DOHC 89.5mm Bore .050in MLX Head Gasket LHS - C4589-050 is a precision-engineered head gasket with a 89.5mm bore and .050" compressed thickness for the Left-Hand Side (LHS).

The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short.
