A media won't distort anything.
A distortion applied to the camera will tent to affect the whole scene. It you
manage to restrict it to a given location, you'll have to change it if you
change anything. It won't work if there is anything between the camera the the
parts that you want perturbed.
Some emissive media can be used to make the flame of the exaust visible.
My take would be to place a long cylinder or a cone with pigment rgbt 1 give it
an ior around 0.99 and use a slight normal perturbation: normal{bozo 0.1
scale<100,1,1>} for a jet along the x axis. Rotate as needed.
