ok. so i bought a 3" mandrel bent pipe for my intake. its in the shape of a "U" so i have to cut it and stuff. i was talking to one of my co-workers at toyota (one of the technicians) and he said i dont have to worry about making fittings for the 2 vacuume hoses that attach to the intake pipe. he said that all those 2 hoses are for is for 2 vaccum switches. he said one switch makes it easier to steer at idle, and the other vacuum switch brings your idle up when you turn your headlights on. does anyone know if thats what those are really for? this guy was just an apprentice so i wanna check witha u guys first thx.
