For those of you who have removed the weather strip from the rear cowl area, have you noticed an increase in heat coming through your vents inside the car? I realize some won't care about this, but I notice warmer vent air after running a bit even with the weatherstrip in place. Warmer air would also make it harder for the a/c if you aren't recirculating the air in the cabin.
I normally keep my vents closed, but I havent noticed anything permeating into the car per say. I think I can feel more heat radiating around the window though when down.
Honestly, I do not think this is even a worth wild thing to do. I have seen ZERO change from removing mine.
