Has anyone done a mod to their stock air box to allow more air flow. Trying to make an effective, functional, cheap mod. All ready have a K&N drop in filter and Flowmaster exhaust.

Thanks,

'02 Durango 4.7L

 

I've got an AEN Bruteforce CAI on mine. Don't really know of any stock mods tho.

 

A guy on one of the Ford Explorer sites took his stock air box out and drilled it full of holes...swiss cheese style...I think they were one inch holes. He was running a K&N and said that he could "hear" the truck sucking more air and thought he felt an improvement in acceleration and power.

 

Ya but that’s a FORD.[sm=shootshoot.gif] the problem is that if you drill holes in the OEM air box you allow hot air in from the engine. I stuck a pry bar down the opening and opened the bend behind the head lights to allow more cold air directly into the collection chamber. The problem is that it sits behind the head lights and a FORD[sm=shootshoot.gif] sits directly in front on the front clip. The only thing you can do is open some of the bends inside of the collection chamber and plug off the air flow from the engine so only cold air gets to it. You might have to drill some holes in the chamber to allow more flow but I don't have a problem.

 

Get a functional hood like this.

Does that hood have a tube that flows directly into the air filter and into the motor or is it just for looks? Also if it does flow into the intake, what about snow or rain flowing into it as well? The OEM air box and where it sits doesn't allow it to happen because of where it is located.

 

There's a little plastic/ rubber sheild next to the rad on the Durango that can be removed/ modified to allow more direct cold air in at driving speeds. Works with a CAI and might work with a swiss cheese stock box. I must confess though I've never seen a stock set up.

 

The two holes go into a larger cavity and the hood is molded to drain any accomulation of water away from the air filter. The cavity has a opening under the hood above the stock air filter box. To make mine true funtional , I had to modify the K&N filter box . I closed the filter into a box with the top open. Installed a seal, and when I close the hood, it seals to the airbox, giving me cold air, forced in ( while driving) from outside.
You can buy the airbox to work with that Keystone hood, but they are to much money. So I fabricated my K&N intake kit.

I'll try to get some pics .....

 

Nice work Digitoxin...I'm saving up for a hood now.

 

Sweet find![sm=hail.gif]Digitoxin.


Where did you find the hood? How Much? And does it come pre painted?
