I have a few questions polkapower. How come you didn't angle the air hat towards the air box to begin with? Second that tall of an air hat fits with that short bolt coming out of the TB with a nut on top? Third are you supposed to cap off those hose inlet closest to the air hat? Finally what year range durangos can you get this from? I'm going to the JY later and am interested.
I didn't angle it because it has tabs on the bottom of the air hat that make it fit snug on the TB and I would have had to trim more of the hood bracing. The angle towards the intake is close to the hood bracing angle. The way it sits now the tubing is in a valley between the bracing that sticks down and provides room for fit. Also I was to lazy to trim the bracing and air hat tabs.
I went to Lowe's and got a longer stud then cut the excess off.
I capped off the breather inlet on the air hat.
I am not sure what years have them but I know they are newer like maybe 93 on up. Just take a look at my pics or print it out and go through all of the Dakotas and Durango's they have. This one was wrecked pretty bad and the air hat was actually inside the truck under a pile of plastic. You should look for the bosch 703 injectors while you are there as well. There is a list of what dodge vehicles to look in on this thread. http://www.jeepforum.com/forum/f13/d...p-how-1305456/
Well driving it around today I defiantly notice a difference in the exhaust note. It's a bit meatier. Seems to accelerate with ease now and with less throttle than before. It's worth it. The tube cost 20 bucks and the air hat was 15.
Just picked up an air hat off a 3.9 Dakota complete with the flex hose, stud, top hold down nut and mounting plate for $15
I'm wondering about the divider plate inside the air hat, to me it looks like a major blockage to smoothly flowing air but then again it its also directly across from the intake inlet on the hat so it may be there to divert the air downward....not sure if I should chop it out or not
Did this to mine last night and on my 5.2L I noticed the Jeep to be a bit louder(not sure what the loudness is I am hearing but it is not as quiet) and it seems to need less skinny pedal to get moving. My install was not as clean as yours tho as I only had tin snaps at my disposal and they quit working at all half way through the cutting process.

Finally got around to installing my air hat yesterday and took it for a spin, made a huge difference in terms of off idle response and has a bit more pickup down low. On mine I cut out the tabs inside the air hat, cut out the divider plate and clocked it twards the airbox outlet. I used a dremel and cut off wheels to make the cuts in the hood bracing and a sanding drum to clean up the edges, left very clean smooth cuts. I also used both the Dakota and Jeep intake tubes and mated them together to; A) make up the difference in sizes and B) the difference in length. A little cutting and its a perfect fit! Anyways here's some pics of it all finished up!
Pic of the finished and installed air hat and intake tubes. Luckily I walked out of the JY with everything I needed to make this work the first time.
Here you can see where I cut the bracing and hood pad out to fit the clocked air hat and intake tube twards the airbox. The cut outs I made in the hood pad by the hood vents will be explained in another thread.
