What is it? Sorry I'm not sure what it is. There seems to be an L shaped hose connecting to a device of some manor. Its on the passenger side next to my airbox. I noticed air or exaust coming out of it when I rev the engine. Who knows what it is and how to fix it? I assume I just need to replace the tube or hose, the hole seems to be on the outside bend of the L in the tube. I have also posted this question in exaust.
