I just got an elbow piece from a big truck exhaust company, they keep those in stock. I got a K&N filter from an autoparts store. Then I got two fernco connectors from Home Depot to connect it all together... very simple and VERY easy. I used a 45 deg. elbow not a 90 because it'll flow better.
oh yeah I have a 99 w/ a 5.2

about a foot of 3"ABS pipe or sched 40 pvc
(cut to size) 2 rubber fernco clamps, 1-90
degree ABS or sched 40 bend and voula.
attach it to a k&n filter, or waste your money on
an airaid (like I did) and attach it to that (that
way you have a heat shield, and support so
the thing doesnt vibrate.)

I used 3" exhaust tubing because I think it looked better than the cheap plastic look. I made a bracket that bolts on to one of the old spots for the airbox so it stays where it's supposed to. Now I just have to work on the heat shield.... any ideas??

I have my K&N filter and I'm ready to make a pipe to connect it to the stock air hat. There's lots of room in there so I was wondering...is there more benefit to a longer pipe with some bend in it or is it better to keep the pipe straight as possible (which would make it shorter)? If straight is better than long, why have a pipe at all--just put the filter on the end of the flexible tube that comes off the stock air hat?

remove your stock airhat, and look at the
shape of the bends underneath, the silencers
restrict the airflow....removing the airhat, and
replacing it with a single straight through pipe,
allows the truck to breath easier, and sounds
sooo much better.

Thanks, D for your response. But I'm still not sure what you mean. I've removed the airhat, but what am I looking for "underneath?" What's a silencer and where is it? If I read you right, I should try and eliminate any bends in the new pipe and that would mean a pretty short distance between filter and airhat. In fact, taken to its extreme, I could almost connect the filter directly to the airhat! But no one seems to be doing that. Why not?

Bottom line everyone wants a cold air intake, that's why the filter is placed far from the engine to reduce sucking in hot air that the engine creates. Now having the filter close to the TB means that the filter is right over the engine, thus reducing power by sucking hot air.
Bends are fine as long as there smooth and not sharp, sharp bends will cause some form of turbulence which will reduce air flow.
I hope this helps!!

Thanks Anthony. A logical answer. I'll put the filter as far from the heat-producing parts of the engine as I can without creating sharp bends in the pipe!!!

Just a note for you guy's making your home brews, you might want to remove the rubber flap at the left side of the radiator, this will let more cool air into the engine area where you are mounting your filters.
The factory airbox takes air from the fender well this is where the flap deflects to.

the only thing that silences the stock intake
are a few, I guess you can call them
bypasses, they are inlets that allow the air to
flow into, restricting the airflow.
visit my photos:
http://photos.yahoo.com/bc/p0intless/lst?.dir=/
I have a picture of the underneath side of the
stock airhat, showing how it restricts the
airflow, and pics of the homebrew intake
Sorry I confused you.

I don't see how the 4.7 air hat can restrict air flow.
"D" shows pics on his site but if you look at yours closely you can see there is no restriction. Dodge built the 4.7 highly efficient. I probably will be selling my 360 intakez and putting the Airaid intake back on. The 360 intakez is a little to loud for me. I have the stock exhaust.

Hey D,
Did you notice any gains by porting your stock TB, I'm thinking about doing if it's worth the time and effort.
Thanks,

pull off the throttle body, and dremel the lip
(right before the throttle blade) down, so it is
even with the overall diameter of the opening.
I used 40 grit (use as smooth as possible
and take your time) sanding drums, and a
polishing wheel to finish it off. the smoother it
is, the better.
Total time, approx 1 hour, including removing
and reinstalling TB...IMO definately worth the
little time and effort involved, I felt a little power
increase, but I didnt expect much. I have
never had my truck dynoed, so I cant swear by
any power increases, because like most
people, I believe numbers!
I did the mod, cause I couldnt see myself
spending $300-$400 on a 70mm or 72mm TB
(just yet), plus, if you look at some of the
messages posted, the 70mm billet TB hasnt
been a very hot item. I think, by porting the TB
i added at least 2mm to the overall dia.
If you use the search box and search for
"ported TB" I am sure you will find way more
info than you ever wanted.
remember to take your time, and make sure
you get rid of all traces of metal shavings
before reinstalling. I rinsed mine off, and
made sure to dry it vigorously before putting it
back on.

Thanks D for the info.
For the rest of you all,
Another little performance improver would be to relocate your IAT sensor to your home made intakes, where the air is cooler than the manifold. This will increase your power, by tricking your computer. Ford and Chevy put theres inside the intake, I don't know why Dodge didn't do the same.
Later,
Anthony

This is quoted from another site. This was done on a 5.9 Dodge Ram.
"I relocated my IAT to my K&N GenII tube. It was a pretty straight forward install and didn't take long at all! I bought a 1/4" National Pipe Thread(NPT) plug at Home Depot. Then I just took the IAT out of the intake manifold, put some plumber's tape around the 1/4" NPT plug and screwed it into where the IAT sensor was. Then I drilled a hole in the K&N tube. Then take the filter off and clean all of the plastic shavings out of the tube. Then screw the IAT sensor into the hole. Then re-attach the cone filter to the tube, and connect the wire to the IAT adjuster. Then turn it on and test it out!!"
This applies to us guys running home made intakes too, it should be very easy to do.
Here's acouple of pics. I don't know if the 4.7 has the same setup. I didn't check mine yet.
You see the Brass bolt that's in the manifold that's the location where the sensor is.
I hope this helps.

Anthony

Dont create a lip. There is already a lip on the
inside of the TB.
the lip makes the opening smaller than the
Throttle blade is. dremel the lip down, making
the diameter the same all the way through.
dremel as close to the throttle blade as you
can, but dont take any metal from around the
throttle blade when it is in the "idle position"
If you take off the stock airhat etc, and look into
the TB, the lip is pretty visible.

This looks like a cheaper mod. that will add more hp to any engine. Correct me if i'm wrong.
I have a 98 RC 2.5,.. I know, I know, it's slow, but it was givin to me and when I have the money I plan on getting a V8 Dakota(not sure but most likely the 4.7). But... between now and then I GOTTA have more hp, I can't stand this!!! I'm wondering how this "home brew intake" thing would do on my truck? Would it increase the hp? If so, would it be just as easy as yall have found it to be for the lager engines? Thanks for any help, I'll take what I can get, cause I have no where else to turn.

Use the sensor that's already there, that's why you need to buy a bolt to replace where the sensor was.
