one problem, I noticed the adapter that is over the throttle body has a hole and attached to that hole on the outside of it is a short hose that goes to a small box enclosure un der the rear of the intake manifold. What do I do with tis hose once the 90 degree elbow is installed for the piping to the intercooler? What is the purpose of this box?
Thanks
