I've always thought a cowl seal is the one that seals the grated panel (below the windshield) to the back edge of the hood when it's closed. I'm not sure what seal is in the picture, but looks like it's not for the metal fender supports in the pic. I just had my fenders off and the ones that go on the support in the pic are more of a rigid formed piece which is shaped to fit the void. They are held to the supports with 3 or 4 metal fasteners. They are there to keep tire spray out of the door jamb area.
