Exhaust and intake gaskets experience significant thermal cycling, vibration, and fluid exposure. Each time a gasketed connection is opened, the gasket should be replaced, a previously compressed gasket does not return to its original thickness and may not seal correctly when retorqued. GrimmSpeed’s gaskets use materials appropriate for the thermal and chemical environment of the specific connection.

This is the correct specification for this connection on the EJ25D DOHC engine.
