Another Snorkel Question

I have searched and searched.

There are a lot of snorkel posts.

In the Jeep Builder's Guide, Bryan Vetrano ran a tube to the passenger side, and then put the cone filter INSIDE of the passenger cowl.

How is this done, and which filter will fit. I know of all other snorkel ideas, I really want to know about this one though. This seems like it would free up the most space ever.

Also, ABS tubing would be fine with a heat shield over the valve cover, right? Or no?

Thanks.

I guess I should have changed the topic title to something cool like "Awesome Snorkel Question" or something.

I am not for sure if it would be damaged, but I would not submit ABS to the kind of temps that are reached under the hood.

I was searching around and I think I can use the TJ air intake which goes across the valve cover.

That sounds like a good option. I just cut a hole in my fender and went from there...LOL
