Hi m8, its your breather case what ive done with mine is removed it and replaced it with a upgraded breather filter that matches my induction kit, but you have to blank the bottom pipe that returns back to your inlet/induction so the car now is breathing a lot better.

Have you got any pictures to just show how you've done it!
