my mates got a `green` mk3 gti 16v induction kit for sale , i currently have a standard box with k&n filter that is drilled and fed with cold feed from the bumper.... would changing it to the `green` induction kit have any benefits , sound , performance , fuel consumption etc .. & does the `green` induction kit have the 2 sensor clip ports as the standard pipe does? or would i be better off sticking with what i have? cheers...
