I work at a dealer, the Mopar Fuel Cleaner kit comes in 3 parts:
One- a can that you dump in the tank
Two- Another can that you dump into a container that is pressurized with shop air and is run thru the fuel rail to clean the rail/injectors
Three- A spray can that is shot thru the Throttle body and cleans it and the intake valves.
We only charge 129.99 at our dealer for it.
Like i said, this kit is made by mopar and is approved on all chrysler gas engines
