I have always used a catch can on all of my GM vehicles since 2001. I recently had my 2016 GMC Sierra with the 6.2 in for a bad injector. Tech had to pull my intake and said my valves and tops of the pistons were some of the cleanest he had seen, wanted to know how often I had the top end cleaner done. When I said never I have a catch can on the truck, he told me it was the best decision I made.
Point is the CC work, while it wasnt an issue on the prev generation engines it is on the DI engines where the valves dont get any raw fuel on them to clean them off.
If it wasnt for me having meth injection on my Camaro I would be trying to figure out a way to get a CC back on it due to my Procharger install.

I've seen K&N filters result in fouled MAFs and cracked headers. Not in every situation but it's possible.
As for CC, I'm not going to duplicate a debate that is already ongoing in another thread, but C&D's long term C7 Grand Sport gained power over their 40k mile testing. Another member posted info from a Vette engineer saying they are not necessary. IMO they are not worth risking warranty issue over, but if properly installed they won't hurt anything and I'd use one along with getting rid of the AFM lifters after the warranty is up.
I honestly don't get modifying the new Camaros... the ZL1 has plenty of power. Air filters and catch cans seem like they don't offer nearly enough to risk warranty issues on.
