Dart Twin Snorkle Cold Air Intake

Now you all need to get a magnahelic and measure the static pressure inside your air cleaner. Getting the correct range would be the trial and error problem. Most can register a difference. Like the pressure at the entrance vs the pressure in the air filter chamber. If you have pressure or at minimum no vacuume (at speed)
in the air cleaner your doing something right.

Hi,
I doubt that there will be much if any air pressure to speak of. I'm assuming that you are speaking at some given ground speed? This mod is intended to stop chugging 180-200 air from the heat soaked engine and ex headers. Or when the dual fans kick in at a stop etc and cram the engine bay with heat. I'll be blasphemous and venture to say most of all the factory stuff did neither. At 70 mph I'll be at 3k and more than likely sucking in all that she will flow but not getting force fed. The K&N Top just lets in sooo much air that the sides are really along for support IMO. Maybe you have seen the Engine Masters episode on air cleaners?

Thanks,
Marion
