About Six-Star® Head Gaskets for FB Motors
The FB20 Engine replaced the EJ20. The FB25 replaced the EJ25, both are DOHC (dual overhead camshaft) and non-turbo. Unofficially, Subaru states that FB stands for “FHI/Future and Brand New/Boxer”. Six-Star has now made available head gaskets for both FB20 and FB25 with the same quality as the other Six-Star head gaskets. Triple layered with the Viton coating by Dupont for better heat resistance.
If you have the new FB motor and need to replace the head gaskets, we have them at a very competitive price.
The Subaru FB engine is the third and current generation of Subaru’s boxer-4 engine. It follows the previous generation EJ-series engine which was introduced in 1989 and the first-generation EA-series which was introduced in 1966. By increasing piston stroke and decreasing piston bore, Subaru aimed to reduce emission and improve fuel economy, while increasing and broadening torque output compared to the EJ-series.
