Interesting Exchange of info, didn't the Factory pull "Cool or Cooler Air" in to the Stock Air Cleaner from the Bottom of the Car. My 73 had a air intake hose to the air cleaner mounted in front of the Passenger back tire. Isn't that why we put Spoilers and Air dams on our Cars because of all the air going Under the Car creating Lift at speed? Why not pull air from under the Car?
