The device on the left is the temperature control for the EGR valve. It stops pulling exhaust gas through the intake manifold when the engine reaches operating temperature. The one on the right is Oriface Spark Advance Control (OSAC) valve. It limits advance to the distributer until the engine warms up. Craig
