Since the turbo Soul is a new combination it lacks aftermarket support. As of right now you would need to fit a catch can of your choice to wherever it fits appropriately. I'm adding both a PCV and a breather catch can to my non-turbo 2.0 Soul+ to help eliminate build up and deposits on the intake valves.
I'm unsure if there is a strut bar available for the turbo version but the SSD strut bar I have on my car tightened up the handling, especially in rough corners. Adding a trailer hitch to the rear also made a noticeable difference. It ties the back of the car together quite nicely.
