I cleaned out the TB today and whilst removing the intake pipe I noticed it goes into a plastic box type thing underneath. I know Vectra's have this and some of the MK6 Escort's.......they are meant to keep induction noise quiet. Thing is if I blanked the inlet pipe to where it is going down into the plastic housing then this would give a far more direct feed to the TB thus = in extra performance......but before I do this do I need this plastic box and what are the thoughts on this mod?
Here is a pic of where the pipe joins onto the plastic box thing.....
