I've been looking for a larger air intake tube for my 2019 6.0, but haven't been able to find anything. I don't want the full cold air intake, just a bigger tube to help push more air through. Has anyone else come across something that will work?

I suspect going to a larger tube will not help, but here’s a relatively easy way to see. T in a vacuum gauge to a vacuum port behind the throttle body...most any port should do.  Run the line into the cab or rig something up so you can see the gauge while driving. If you go full throttle and the gauge drops to 0, there’s no restriction. Watch the gauge through the RPM sweep as more rpm will require more air. If you do see a restriction (I.e., vacuum showing > 0), it could also be the air filter. 
 

there may also be a MAP reading accessible through obd2, which would be easier to monitor, but I’m not sure.

Seems like all those things do is make it really loud inside the cab....but if that’s what your going for, I’m sure you could make something relatively cheap

You could try intakehoses.com.

I’m sure you could put something together from there.
