Why would you need a connection from the air intake hose? My sportage 2.4 just feeds from PCV to the catch can and than another one back to the manifold. That "breather" looks like its going to be restricted once the cover is on. No outside air, just hot engine air. The best thing is to try to keep the hoses short, to much vacuum lines = more travel. Just my 2 cents.
So this can is meant to "emulate" a dual can kit, hence the hose from the intake. If you've seen other KDM dual can kits, you see the most important one is from the PCV but the second can is from the intake. You may be right about the breather but this install video was meant to be done the way the kit comes. I mentioned using a hose to have the breather outside of the cover so people have the option. And as you said, the most important is a single can from the PCV side but this is meant to be an affordable option to cover both (instead of spending on a dual can kit).
Hey buddy just want to say that your videos are awesome but I think I speak for most people here that we want to see veloster content not much people are doing theses mods to a tucson. I say this with all respect have a bless one !
I get you. But I'm mixing it up because I won't always have a Veloster so I kinda need to focus on other things as well. Though this install was on a Tucson, the N/A Veloster is similar so I figured i'd show the N/A install.
Shouldn’t the check valve be installed on the inlet hose from the engine and not the outlet? I thought the idea is to prevent the oil going back to the engine?
It has to do with vacuum source and less as a "fluid check valve". This is their reference from their site on the check valves: "The V3.3 catch cans are used as an additional suction source of help to the blow-by problem by Adding additional vacuum location just in front or upstream of the throttle body or TB inlet and we utilize one-way inline check valves that select the best possible suction source when the full throttle is open."
Why are check valves needed?

Make sure that "Catch can" is used for GDi engines only ..

I run a catch can on our 2020 Tucson
Do you know if a air intake from a other Hyundai would fit on the Tucson.
It's possible that an intake from another Hyundai may work. You may need an adapter to fit the throttle body size though.
Thanks

Why are you creating so many restrictions in the line, because of blow by with these engines this line should not be restricted.
I see what you mean but the install was done as specified by the manufacturer.
