Yea, for turbochargers need catch cans that works to prevent oil blowby. If you don't add one, the oil can coat the couplers and fins inside an intercooler. Just make sure to research them before buying one because there are catch cans out there that doesn't do much of anything.
I'm a firm believer in running a catch can. It's never a bad idea to play safe when it comes to your engine. Reducing any blowby is better than letting it all-by. Hopefully something like the D3PE catch can comes out, love the way they look.
