How do you plan on opening your hood if your tubes are running to the vents? also keep in mind that the vents are for air to escape not to catch air, this serves two purposes. 1st it allows air to flow through the radiator at an increased velocity and out the hood, this helps eliminate the air from flowing under the hood and out the bottom. 2nd helps eliminate lift created by the air traveling down and under the car in turn forcing more air over the car and helping with downforce.
