The bottom line is that while in principal a snorkel works, it won't work at all on any modern vehicle driven by electronics (such as your TJ).
The only time I've ever seen a snorkel work is on an older diesel. Those old diesels are almost entirely mechanically driven and therefore don't really have any electronics to short out. No modern vehicle would benefit from having a snorkel whatsoever. So unless you have swapped in some sort of old, mechanical 4BT Cummins engine, then you won't benefit at all from a snorkel.
So what you are saying here is that I NEED a 4BT swap...
