05 LJ Water Passenger Side

And your rig has it or it doesn’t?

The one in the photo came off my '05, replaced it with this...

This foam does not exist on an '05, suspect it was a poor attempt by Chrysler to keep water out of the fresh air intake on earlier models.

Rather interesting non-factory plug welds in that photo... :unsure:



Poorly aligned doors or bad door seals are often overlooked for items like leaking heater cores and plugged drains, but are quite often a leak source. Replacement seals are shit, unfortunately.

That's actually factory seam sealer globs
 
And that is? You replaced it due to water leaking in?

It's a cabin air filter housing I designed and 3D printed. I did not have issues with water coming in my cowl, however, I do get water in the passenger footwell every time it rains. See previous remark on door seals.
