I'll try and explain this without a photo. If you look down at the filter body, it has two pipes, one which is the 90 degree bend one which goes to the throttle body and another pipe, which comes off the body.
Mine doesn't appear to have this second pipe and instead has tape over the end.
Where does this other pipe go to and is it important?
