Cosworth 20002145 High Performance Head Gaskets Subaru WRX STI EJ25 2.5L

Cosworth High Performance Head Gaskets are engineered to seal in power under the most demanding conditions.

Constructed from stainless steel with a folded stopper layer, each application features superior sealing compared to conventional multi layer steel gaskets.

Additionally, Cosworth High Performance Head Gaskets are manufactured from pre-coated die cut stainless steel resulting in uniform coating distribution and consistent shape.

Suitable for EJ257 with single AVCS

Note: Subaru gaskets are sold individually. Order two for a complete set.
