I fully understand what a catch can does and why it would be beneficial, my question is if Ford has made any revisions on the '15's to mitigate the need for one, ie adding a fuel spray on the intake valves to minimize carbon build up? It seems they revised the intercooler to prevent any pooling of condensate, did they make any other improvements?

Just took home a new XLT 302a S-crew 3.5 EB today and have been planning on adding a catch can, just looking for any reason not to do so?

 

I ran my 2011 Ecoboost for over 65K miles with no issues and no catch can...... if you don't have an issue don't worry about it

 

that should keep you entertained for the next 2-3 weeks...

The condensation issue with the intercooler seems to have been resolved. No one has been reporting Limp Mode from boost pushing water into the combustion chamber. The valve coking issue is still there though. If keeping the valves clean and removing blow-by vapor is a concern than a catch can is an inexpensive add on. If not than no need to purchase one like waphillips said.
