What did you expect would happen? The stock intake pipe has holes for the metal bov return and oil breather to slot into so obviously that wasnt going to work without some hoses. And when you look at the placement, its not even near where the originals holes are.
I dont understand how these guys sell so many when everyone who buys one just ends up pissed off. Classic example of getting what you pay for.
And what do you mean 'no dose'. If your bov is blocked off then it should dose even with the rubber intake and be a fair bit louder with the metal intake. Unless your still running an air box, in which case dont ever expect a loud flutter if thats what your after..
