Hi
I need some more help my 92 Rev 2 turbo has had it's charcoal filter removed

(not by me) the 2 pipes on top of the throttle intake have been chopped and bolts stuck in the ends of the hoses I don't know why this has been done and what if anything has been fitted for someone to do this.

Is this a mod if done in association with something else?.

.

Do I need to put this back? Any help will be well received
