Airbox "Air Scoop"
I just recently did the airbox mod to my vehicle, and I just really feel like I may not be getting the best out of it, especially at higher speeds. Now I'm not experienced with cars at all, but I really don't think that behind the headlight is the best place for maximum airflow. So what I was thinking is making a funnel-like device that better directs airflow from the grille and under the truck to the airbox, resulting in maximum aspiration without installing a turbo. It would literally "scoop" air to where I want it.
How does this sound to you guys?

Re: Airbox "Air Scoop"
I wondered about this too

Re: Airbox "Air Scoop"
My only concern is that the funnel device might have awkward bends in it that constrain airflow even more

Re: Airbox "Air Scoop"
Yeah, that's what concerns me. I also wonder if it will increase drag and lower my mpg...
I may need like a windtunnel chart or SOMETHING because I need to know where the air flows the most

Re: Airbox "Air Scoop"
So I think what I'm going to do is use something like this to rig up to a funnel-like device that goes behind the grille, next to the radiator. However, I probably will use tubing that is more in the neighborhood of 6 inches. Going to cut a gaping hole in my airbox and hook it up.
Now this will cause permanent damage to my airbox (and possibly keep me from passing smog?), so I really need some feedback because I'm just a noob, and I hardly know what I'm doing.

Re: Airbox "Air Scoop"
Personally, I would leave it stock. You won't gain any performance from this, especially on the 3.0. If you do decide to do this, use a junkyard airbox to cut up, that way when your done experimenting you can go back to the stock box.
Plus, with what you describe, wouldn't rain water/bugs/dirt also be sucked in easier?

Re: Airbox "Air Scoop"
If you drive and or splash in a lot of water, the intake behind the head light is liable to receive the brunt of that and water in your air intake is not a good thing. OF course this is a worst case scenario but you never know.

Says who? From what I gathered, one of the reasons why the 3.0 can't gain much power is due to the poor intake location - the reason why CAIs won't work (yet they do on nearly any other vehicle) is because they're just sucking in hot air.

A screen should negate the bugs and the filter should negate the dirt, but I don't know if the filter will keep the moisture from getting in.

Re: Airbox "Air Scoop"
your not suppose to notice a difference with the air box mod, yes it has better air flow but not enough to notice and the reason its behind the light it the prevent debris going through because if its in the open you will be changing air filter's a lot more, if you want to increase the air flow more i would dremel the opening bigger.

Re: Airbox "Air Scoop"
Gotcha. I'm going to take your word for it, since I'm young and new to cars and hardly know what I'm doing

It's just not the same around here now that FireRanger doesn't stop by as much.
