This TRW exhaust valve is used during cylinder-head and valvetrain repair at the engine cylinder head. The application must be checked by engine version, valve geometry, and year rather than vehicle name alone.
TRW has longstanding experience with engine-valve production, and its replacement valvetrain components are cataloged by valve function, dimensions, and engine application.
