There are 2 black actuators on the upper intake manifold with an "L" and "R" on them. My question is which way do the hoses from them point? When I took apart the manifold to clean all the ports, the lines were facing AWAY from the throttle body. Now I'm being told that they are supposed to be pointing TOWARDS the throttle body. Please can someone answer this dilemma I'm having? Would this change the performance of the vehicle? All I know is that they control the butterflies to open when the car hits 4000 RPMs for the secondary's.
