arm rest vents

They vent air thru the openings in the arm rest and out thru the door jams to provide an air change in the car. They require cutting holes in your door panels and door jams. I dont know if they work or not.

They are what Precisionproformance is calling "cabin pressure release system" ($130)to vent cabin air to the outside. It is supposed to make the AC work better. I don't have them on my car, so can't comment on how well it works. Modern cars have similar systems hidden in the doors/interior.

Vent air to the outside?? Wouldn't it be better to put them in the seat cushion bottoms then?? That is where it is really needed.

THis is a very smart system. The large grilles cover a hole you make in you make in the door panel, directly behind the armrest / doorpull. This lets air travel from the cockpit, thru the grille into the door. The small vents in are installed on the outside of the door jamb (not sure if this is the correct term) just above the door lock mechanism. THis lets the air escsape out thru to the outside.

I had this system on my car. It made a noticeable difference.

I would say it makes a lot of sence. In the HVAC Business ..in any Habitable enviroment ..its required at elast 15% outside air. This added to the cockpit would allow the AC or Heat or just ventilation inside the car. Pumping ehat or AC into a sealed enviroment seems like it would take twice as long.

Another way to provide an air exit route is to put grills in the emergency brake cover that is on the passenger side. The structure there is already directly open to the outside. No need to cut into the door panels (metal or trim) if you use the emerg. brake cover.

If I'm not mistaken those little vents that go in the back of the door jam have soft rubber flaps to allow air in as needed but not out ... seems that it has the same principal as the old 69 mustangs had.

Ok, makes sense to me. I dissasemble doors all the time and they do have a vent system in most. It will also help the door close better because trapped air can escape. Most do have the rubber flaps. I don't know if this is true but years ago my friend had a 66 Barracuds Formula S. He told me that that was the first car to employ auto cabin vents. I think they were in the rear though. I don't need them for my button car because I have the mystery pull knob.
