I got a used depo intake not realizing the fitting for the breather hose was missing, anyone know what size the fitting is?

So I have been on the fence with putting a cold air intake in my 2017 Focus ST I've been bouncing between a few different ones but I wanted to ask what everyone's opinion is on the Injen Cold Air intake. Is it worth it or should I be looking at a different brand or style? Thanks!!!!

Hey guys, I recently bought a COBB CAI from a buddy, but it's missing the coupler for the turbo side of the aluminum tubing. Am I correct in assuming that the factory stuff down there won't connect with the intake tubing? If not, what could be my options? Does anyone sell just the couplers...
