It has to be bent almost 90 deg which puts a lot of stress on the outside bend.
Holes eventually develop due to the erosive effect of air flow compounded by the heat and stress.
You can patch the holes with duct tape or you can get a factory or aftermarket replacement part for $20-50 which include the bottom 90 deg adapter.
I got tired of looking at the duct tape and was not satisfied with the original design.
So I bought a 90 degree silicone coupler hose for about $12.
It has an inside diameter of 70mm with 4 inch legs.
At the air cleaner outlet it fits snug but extended too far out so I cut off about 1 inch from the end.
About 1 inch must also be removed from the other end.
The hose is not that flexible and a little tough to cut using a utility knife given its multi-ply construction.
In order to provide a flexible connection to the bottom 90 deg adapter I reused sections of the old hose.
I cut off the bottom section of the old hose with 6 rings left.
I cut off the top section of the old hose with 1 ring left.
The idea is to join top and bottom sections by inserting the ring of the top section inside the top ring of the bottom section.
In order to fit the top section ring the circumference has to be reduced by about 1/4 inch.
The hybrid section can then join the silicone hose and bottom adapter.
The flexible section is compressed more on one side because the angle between the outlet and inlet axes is > 90 deg.
