The wife had my 2015 jeep cherokee north in for an oil change today at the local dodge dealership. During service they pulled air box and checked air filter but in the process they broke the fitting off the airbox that the vacuum line is attached to. And tried unsuccessfully glueing fitting back onto airbox. Glue didn't work so they have a couple zip ties holding fitting on, and they cant get a new airbox for approximately a week. My question is. What is this vacuum line for and what damage can occur if dust gets sucked into it. We drive on alot of gravel roads so avoiding dust is not an option. Thanks for any help.
