Product Description

The Cometic C4264-030 is a 100mm MLS head gasket built for Subaru's EJ25 series DOHC engines. Its multi-layer steel construction and Viton-coated outer layers provide a durable, repeatable seal without re-torquing, making it a common choice for both stock rebuilds and turbocharged performance builds.
