I have catch cans on my turbo Veloster but not on the Z. Boost makes more blow by and crankcase contamination + direct injection and I have been shocked at how much the catch cans have collected between oil changes. That said, when I changed out my intake manifolds with the Z1 400HP ported manifolds, I was very and pleasantly surprised how clean the ports and intake vales were, quite pristine actually(32K miles). So I think they really are not needed on this car in NA configuration. Also, I have tracked this car so again, quite surprised how clean everything was. Will they hurt, no and they may help to some degree depending on the age of your engine and how you drive. Your mileage may vary.
