I noticed a TJ when I was walking outside to grab my CP Writing book and it has a hood scoop in place of the stock vent that is on the hood. So my question is does it actually help? I know what hood scoops are ment to do but does it actually work on a Jeep?
That big vent in front of the windshield is your fresh air intake for the heater a/c.
Amy has one, I don't know if it helps since her fan is always on but it does keep some of the crap out of the vent.

Arguing with a truck driver is like wrestling with a pig in mud, eventually you realize the pig enjoys it.
I had one too. It was the $20 plastic one. It lasted about 5 years. After about 2 years the little supports broke and made an anoying Buzz untill it cut them off. At 5 years it just started cracking all over. $20 for 5 years.....not bad.
I liked the way it looked. It did seem to force more air through the vent which helps on Hot Days (no a/c). Heat does not need help....at least in YJ's.......cooks my boots.
Remember......face the opening Towards the windshield.

Ditto, on what the others said. It is just to keep depris, from clogging up your fresh air intake. That is all. If you park under trees, or like to use your vent a lot, not a bad idea. But as already stated, it does not aid in engine performance.
the air comming rolling up the windshield would creat a vaccuum drawing air out of the vents not forcing into them. thats seems feasable, i wasnt even thinkin that till u mentioned, i was just thinkin more airflow with ram air than without ram air, but facing the w/s probably would have that vaccuum effect. isnt that vaccuum actually the same way cowl induction works. pulls that hot air out of the engine compartment allowing for colder air to be sucked into the engine
I have had one for about six years. I mounted mine facing out. I have never seen one facing the ws. It makes a big difference with the vent flow. Especially on those warmer rainy days where you can't drop the top. Before you stick it down, make sure the jet for the windshield cleaner isn't blocked. Mine is slightly deflected on the passenger side.
