Thanks! The next couple videos will be primarily camper van build stuff. I'll be doing a bunch of 7.3 engine work eventually (notably injectors and glow plugs) but it's gonna take me a while before I can afford those projects.
Yeah, it's custom built by the previous owner. He modified the intake with a piece of PVC to accept dual K&N oiled filters. I'm not confident that it's the best option but it is what I have.
I have not. Got a link? I'll check it out. And yeah that is a good topic. I think the original airbox isn't a bad option but on many vans by now it is cracked beyond repair. I've seen a few options but haven't messed with mine other than to clean and oil the filters.
