I'm sure this is in here somewhere but I can't find it. I am going to make a z tube this weekend and was wondering if you all can help? I would like to make it 4" pvc, but don't know if it will fit. Which is better? 4" or 3"? Also, I need to order my K&N cone filter. Anyone know the part number off hand. The bigger the better as long as it fits. Also, if any of you have pics of your home made intakes, it would be greatly appreciated to see the pics please. Thanks again fellow dakota owners. This forum is awesome!!!!

4" fits barely I did it, and there is no room to spare but I wanted maximun air flow and a rushing effect at the tapered flange. You will need a rubber 3"-4" adapter. Comes with 2 hose clamps and has a nice smooth chamfer inside to rush the air into the TB. You will nee 1 90* elbow and 1 45* elbow along with a couple feet 4" pipe. Use the black pipe it's more heavy duty than the white stuff. It paints up easily also. You will also need the PVC glue. Read the instructions on the can do the lay out and check the clearence to the hood. I found conecting the 90* elbow right to the flange allowed it to clear. Also remeber I have NO A/C in my truck so I am not sure if that will be a problem making it fit.
Anyways you have the idea and should have no problems. My girlfriend (I hope) has taken my camera to Yugo for a month so I can't up load a picture for you.
Just check it out and be creative.

I was goin to make my own intake just like this guy did -http://www.geocities.com/woodrufj/dakota/eng2big.jpg
In my opinion though it looks pretty crude and ghetto... And since the new Flometrics TB's will be comin out soon (which require a larger intake flange than stock), im goin to wait and see if intense performance will make a z tube made just for the new TB.

I would not go any bigger than 3 inch's. Most turbo charged imports only run a 3 in down pipe. The reason behind this is velocity. If you make you intake pipe to large the air charge comeing into your engine loses velocity and this will realy hurt your low end torque. You realy do not want to lose low end torque especialy in a truck. I am just guessing here put I would imagine that a 30% increase in the diameter of the stock unit will probably increase air flow about as much as the rest of your stock engine can utilize.

I'm very happy with my intake that I designed. It doesn't take much to build and to install, the power is very noticeable at 1700rpm to about redline. The sound that the intake makes is so deep and loud everyone can hear me coming. It's great.
Fot80 already posted my site, Chad if you have any question just ask.

Thanks for all the info guys. I think I will go 3" for now. Also, about the K&N, 6x9 with 3" inlet sound right? Will it fit? Thanks Again

Hey sandman I don't think 4" is hurting a V8 at all. Most turbo charged imports are 4 bangers. K&N even makes a cone filter to fit the outside diameter of my tubing which is 4 1/2". I am very pleased with this mongo intake and have a feeling the stream of air is actually being rushed and compressed right at the TB.
What about the older V8's with the big filters right on top. They draw air in from every direction and superchargers ram the air in. An engines HP is mainy the result of how much fuel and air it can burn. The more fuel and air crammed in the more HP. Of course there are other variables as well but this is basicly it.

I put a 14" chrome air cleaner right on top of my TB with the help of a 3" spacer to raise it above the radiator hose. I think it made a real difference in performance and looks. Also sounds good when you stand on it.

Think:high pressure area = low velocity (flow) and low pressure area = high velocity (flow).So the larger inside diameter of the intake duct the higher the pressure and the lower the flow.The throttle body is a low pressure area (high flow) while the intake manifold is a high pressure (low flow) area.

Jeffster K&N also makes cone filters that fit black hawk helicopters engine intakes. That does not mean I want an intake filter 3-5 feet in diameter just because K&N makes them and I can find PVC pipe that size. You may not be aware of this but you can calulate the exact cfm requirements of you engine with some realy simple math. If i remember correctly you need max rpm,bore and stroke. Then you can compute what size tube you need to flow that amount of air. Anything larger than that and you are just wasteing space under your hood. Jeffster your engine can not even utlize 600 cfm of flow and I am going to guess that your 4 inch tube with a K&N is probaly exceeding 2000 cfm of flow potential. A drop in K&N filter to replace the factory paper element would probably get you about as much improment as you will likely see and it will save alot of time and money over fabricateing if your engine is stock. It will also maintain that stock look. You can also build a 3 inch system and use Stainless Steel tubing or polished aluminum with virgin silicone hose to make smoth gradual turns and bends leading to the TB.This wouold look alot more tricked out then PVC. I brazed an a copy of K&N's filter chargers together out of strips of steel I cut from an Army mess hall can of coffee about 9 years ago and after I ground all the brazed joints and painted it up it looked wonderful. I put a K&N cone filter on it and it is still on that truck today. You would be amazed what can be done in an hour with an anvil, hammer, brazeing kit and determination.

Just finished 3" intake tube with the 6x9 K&N. All I can say is WWOOWW!!!!!!! It is awesome. Looks awesome and sounds awesome, and the performance is great. Just step on the gas and the a$$ ends goes sideways. This thing kicks a$$. Thanks for all the info everyone. Now I just need to find a flowmaster cat back system for my 00 4.7 Quad Cab. Thanks Again.

I have done the drop in before sandman and felt no difference. This tube actually looks very good and those that have seen it think it's awesome. It's all painted in alluminum and has really giving me a significant boost The elbows inside are very smooth so I am not worried about that at all.
I posted more about it a miniute ago on >no intake<
