3. The driver side hose leading up to the factory air box will also need to be tightened up and rerouted. This hose
emanates from the side of the engine and juts out over to the factory air box. Remove this hose. We will use the
remaining 90 degree elbow to re-direct the new hose provided towards the front of the engine which will hide
under the front end of the new fuel rail cover. Attach the new hoses 90 degree elbow directly to the factory air
box so that the hose turns down towards the floor. Then reroute the hose over to the plenum in such a way as
to allow it to lead up to the plenum port. Attach the rubber elbow so that the end of the elbow faces the front of
the car. Bring the new hose up to this end making sure there are now kinks in the hose that may limit its ability
to allow vacuum and also have enough slack to allow the new fuel rail cover to set in place properly. Depending
on how exactly you route this new hose you may or may not need to trim the length before you attach it onto
the new elbow.
