There has been an issue on some cars with a power pulse pipe coming loose and leaking air, its only the pipe that gets replaced not the power pulse system, it is a well documented fault with a TJ.
I had my pipe replaced at my normal 12 month service, it is a precautionary change, not all cars had a problem, I had no problem with mine.
They also changed or added a EGR bracket at the same time which is another TJ. You should ask if your car needs this and if they are going to order the parts and do it at the same time.
My car is a 2017 MY.
