What is that hose that goes into the Valve cover that is located under the word TWIN in this following picture?...

http://memimage.cardomain.net/member_images/8/web/332000-332999/332653_18_full.jpg

I do not have the second hose part that goes down the engine? Do I even need that hose? Is that ok or do I have to plug it up (the gold piece after first hose ends)...I only have the hose that originates from the black box near the rear of the valve cover on the turbo side...Is that good enough?

Thanks

It goes down into the intake pipe after the AFM and before the turbo inlet. Its part of the oil catch can breather system. You can replace it with a small air filter as long as you block the hole in the intake pipe.
