Has anyone done one of these on a 4.9L? Does the kit include some sort of filter isolator/fresh air feed such that the engine isn't ingesting hot engine compartment air?

I've got one on my 5.0L and it just replaced the air box setup, and the stupid little air inlite horn above the grill with a tube from throttle body to where the airbox used to be, and a big cone filter on the end of it. I supose it can suck hot air in, but if you are moving then fresh air is being sucked into the engine bay anyways...
