So I had my local dealer install a Mopar cold air intake into my 2013 Charger R/T maxx. I stopped at a gas station to run in and get a drink and noticed a squealing noise from the engine. Almost sounded like a bad belt....but could not pin point it. It did it whole time I was in gas station. By the time I got home it had stopped, however after I turned off the car I had a extremely high pitch squeal that lasted about 5 seconds after the engine was off....any ideas?!?!?! is this from the cold air or a more serious issue?!?! Any help would be awesome.
