Tomei Head Gasket for FA20 VA Subaru WRX (TA4070-SB03)
The Tomei cylinder head gasket for the FA20 Subaru WRX is highly heat-resistant and durable, ensuring superior sealing for high-power applications. It features thicker seals around the bore to contain pressurized gases within the combustion chamber. Unlike other gaskets where thicker bore seals may weaken oil and water route seals, Tomei USA gaskets are specially designed to evenly distribute pressure, maintaining a high-quality seal across the entire surface.
