The car would run without them, they're used to help warm up the intake manifold (similar to the hoses for the TB). It probably wouldn't have much effect to remove them in a warmer climate, but if you were say in Canada then you might be better leaving them. When the air coming in is too cold, the fuel won't atomize properly.
