I diddnt have a welder at the time so rollen cole(I think thats his name,he may be here?)made this for me.It is 6'' into 5 into the k&n 4.I have a lid for it i removed it to do some work.I also went into the fender and i direct the air into the filter.If you look at the factory fender hole it goes in a line to the hood hinge.So i blocked it off to make a right turn into the filter.I also have a 3'' hole in the cowl to try to suck more air from the dead spot below the windshield.You can sorta see the 3'' hole at the top of the air filter.

What kind of power level are you looking for? Are you pulling down the stock filter minder?

all I run is a 65 hp chip. I just want to be able to use 100% of that power. I heard an better air intake will allow you to have more useable power and better air flow.

Take you filter minder out and suck on the filter minder... You'll find the filter minder is REALLY sensitive... So as long as the filter minder isn't moving then you know you good for the air filter your using... This applies to ALL filter setups...

So you can spend $200 bucks on a air filter setup and not change much... :rolleyes:

Yup it looks like they know about the cowl air space as well.Scottys old air filter set up would go in the 3'' hole.I Have a nice lid for mine as stated but it just seems i am working on mine more than driving it:banghead:

I took a piece of 3" mandrel bent tubing from Summit Racing and cut it, and rewelded back into position. Wasn't too hard to do, but I wish I would have came out a little smoother underneath.:( Oh well I get bored someday I'll pull it off and add some more filler and repaint to make it show quality.:thumbup2:

--- Update to the previous post...

This one I think:

Then just take a piece of 1/4" plate and cut a hole in it. Plus the four smaller bolt holes. I used a plasma to do it, but a hole saw would work too.:thumbup2:

Cool.. Doesnt look to hard to make.. Did you notice any differense in performance.. Your egt lower?

--- Update to the previous post...

also does the afe torque tube make any difference..?

Not really. I think the EGTs maybe dropped a little faster, but not very much. It is mostly for looks and the ports for water meth down the road!:thumbup2: As far as the AFE Torque Tube, kinda the same deal. With both I seemed to be able to hear a little more air sucking so maybe that's a good thing!!:lmao2::thumbup2:

OH.. Maby I have no need for it then.. I figured it lowered egts a bunch.. But you probually got a point on the air flow.. Its gotta flow better the the stock intake horn..

I painted it myself. Took a while to strip all the old paint off with my little gravity feed sandblast gun and aircraft stripper.:thumbup2:

I think it looks good.. You should of painted the intake horn red also. and the turbo.. That would look pretty neat.. Just my opinion...

Yeah that's just too much red for me. What I plan to do when I twin it is do a contrast of silver tubes and red brackets and such. That's my plan at least! The theme of the truck is black, silver, and red. Nothing too out there but looks nice together!:thumbup2:

I did mine while the truck was done during the VP, injectors, and ps pump install. I think I used high temp paint. I can't remember now. It has held up fine, just some nicks and such from installing other parts after word. I would like to get the red Cummins one with "Cummins" on it instead of "Dodge." And it is red powdercoat!:thumbup2:

I know that 3rd gen guys use 2nd gen intake horns for better flow. I went one step further and got a GDP intake horn. Its a very nice piece. What I saw was decreased IAT's, increased throttle response, quicker spool, and about 100-150 rpms quicker to 30psi. EGT's were negligable, but on a 3rd gen the IAT's and Ambient are very close, and a 1* decrease in IAT is only good for a 1.5* decrease in EGT's. So even if you drop IAT's 50* your only going to see a 75* EGT drop, and with my 3rd gen I only dropped about 3-5* of IAT's. I am very happy with my choice, but the 3rd gen is MUCH more restrictive to start with, so I wouldn't expect as high of gains on a 2nd gen.

Yeah the 2nd gens don't gain very much with an intake horn in the power department. Maybe once you cross the 500 hp area it might but not sure. I did it mostly for looks and maybe a little better flow!:thumbup2:

Which is a great reason to do it... Just don't want someone to be disappointed if they do it. They look 100x better!
