I got a 2007 Subaru Impreza , I’ve had the car for couple months and noticed that some of the lines aren’t connected or where / blocked with random stuff ,
I have no clue where these hoses are suppose to be connected to
their are two on each side that aren’t connected ones near the spark plug that are suppose to go to air intake box , and then the other two one on the left side which is around the same area and the other one which is top of manifold
