I think the problem would be (and maybe why it doesn't extend further) is that people running a cabin air filter would not be able to get to it. If you did make something, it would have to be easily removable to access the filter. Which would mean it would need some sort of seal or gasket where it attaches to the flange anyway. You'd just be trading one problematic part for another one IMO. Using an adhesive to attach the existing deflector will eliminate any problems anyone has with it for good.

BTW... I mentioned using RVT sealer to adhere it with. Another good option is a tube of windshield adhesive. That what mine is stuck on with since I have it readily available. It's black and you can see it in the pics where I pulled it part of the way off. Never use straight silicone on a painted surface. Make sure it is non-acidic silicone, or specially recommended for automotive use, if you do. Regular silicone will eventually cause the paint to peel away where ever it touches and will cause rust.

Holy crap. I always wondered why my car's floor was wet sometimes after it rained, just assumed the street flooded or something. That's crazy! Thanks for the great post!

You can get them at most automotive parts stores. But in my experience, as I have one, they dont work to well on our cars because its hard to get it under the wiper. I also have a battery terminal puller that works MUCH better which can also be found at most automotive parts stores.
