There is a differences in temperature decrease w/o the weather stripping. After reading the long post about it, i decided to do the same to my car. I took off the weather stripping at the back off the hood and it seems to be releasing slight amounts of heat. It's better then nothing, but at least there's heat escaping.
It's no big deal, just a rubber lining to keep noise and heat in the engine bay when it's cold outside.
has anyone taken all the weather stripping? The two rubber lines upfront too?
