Message:
I have been looking for a cold air intake for my 1990 V6 dakota. Have had no luck. So I thought maybe a K&N cold air kit for the 92+ would work. Any comments are appreciated.
Aboutht e home brew system. I thought about getting some 3in dia PVC pipe. putting an elbow in the middle of it. And painting it with heat resistant paint. My question is about hooking it to the stock air box. Could I buy a simple rubber fitting and attach the PVC to the r. fitting and to the airbox? Of course take out the stock filter. Would this allow my enginge to get the cooler air from the front of the engine comp. and run it throught the TBI? Any help is good. Thanks for your time.

Hi Joe,
I myself have done like alot of the others on here and made my own homebrew "Cold-Air" intake. What I did was go to Lowe's, buy a 3" opening diameter Fernco connector, some 3" dia opening abs/pvc tubing, a couple of 90 degree elbows also 3" abs, then went to Autozone purchased my K&N and a rubber grommet kit with 45 degree pvc/plastic insert to put in intake tube and connect to crankcase vent line. So when all was said and done it looks something like the link to this pic here. Works great and man does it sound awsome. There have been alot of posts on this type of setup so just do a search for "cold air intake" if you want more info. Good luck, sorry for long post.
Rick
This is a link to Bakerman's setup, mine is almost the same.

Rick,
also how much did your K&N filter cost? Just getting an idea of what to expect to pay for this mod.
Thanks again,

Hi Joe,
Well that is the thing with me, I kinda splurged with the filter. You can find conical/round filters that will fit online for about $35 to $50 bucks. I didn't want to wait so I just found one that would work at Autozone and slapped it on. It cost me about $54 so that is kinda pricey. If you do the search and type in Bakerman, in the string about his intake there is mention of part #'s and prices and where to order. Lots of guys got there's online. I was impatient! LOL sounds awsome tho and performance is better. Just don't forget to reset your computer afterwards. Need anymore info let me know.

Joe here is a link to an e-bay auction. You may have seen these before, but mine is pretty much identical. Just thought I would give you another link. If you don't find a commercial rig, homebrew is next best thing!! I love mine. Goodluck

Sorry, well what I have been told is if you disconnect your neg bat terminal it will clear the computer of anything stored in its memory. I also read an article in "SportTruck" where they added a Volant intake on a Dak and then had the computer reprogramed to take more advantage of it. Also I have seen in some strings on here where people say the computer will adjust itself after a few days of driving. So with that in mind, what I did was disc the neg bat and then reconnected after I was done. After driving a few days mine seems to be great. The sound from under the hood is excellent and performance seems to have improved. Don't have any numbers tho sorry, but have sure turned some heads when the hammer is down. hehe good luck

Thank you Rick and Erik. I will need your help again though. I went to Home Depot today. I looked around the store and found the plumming isle. I found typical PVC pipe stairght and all angles. Will this normal PVC work? I did not buy anything because I wanted to be sure it was the type pipe you were talking about. The worker man told me it was not very heat resistant and it would probably not work for long.
What is this ABS you talk about? I know it is hard plastic but is it also a type of pipe? I did not find anything called this in the store. Please have patinece with me, I have never made a home brew mod before.
Thanks for your help!

No problem Joe, I know the feeling. Ok the ABS/PVC pipe is pretty much the same stuff. The pipe I got is black and here is the info off the side of the pipe, (NSF-dwv) P852(G)04 12 01 2BRISTOLPIPE 3" COEX ABS CELLULAR CORE. As far as thickness, it's opening is 3" but with the walls of the pipe it is about 3.5 inches in diameter all together. So far everyone I know has not had a problem with heat, and it should not be a problem at all. This stuff is pretty sturdy. Did you paste the link to the auction on e-bay and look at the pics of the one there? If you don't think HomeDepot has what you need try Lowe's or another store if possible. Let me know how it works out.

Rick, yeah I looked at the ebay auction. I have seen it before and thought about trying to get it. What my problem is, is my Dak is a genI 1990 V6. I has a round paper filter inside a round air assembly. It doesnt use the newer air box I have seen that uses a flat filter. So I will have to hook the end of my tubing to the stock air assembly. I will simply remove the stock type paper airfilter and only have the K&N cone on the end. So I cant really use that ebay auction. I think it would be better to fabricate my one. "Fabricate sounds more prof. right? haha" I will look for that ABS/PVC pipe tomarrow in town. Is that tubing hard or is it somewhat plyable? The PVC I looked at today was hard as a rock. Thank you for your patience Rick. Have a nice Monday!

Ya Joe, I wasn't telling you to use the e-bay one, what I was trying to find out was if you went and looked at it to see what the tubing looked like. hehe no problem. The tubing is hard, the 90 degree elbows that I got are hard and the only soft thing in the setup is the 3" dia rubber fernco peice that is used to connect the abs/pvc pipe to the throttle body. Good luck and you have a nice monday also.
Later,
Rick

Thanks Rick, I am in your debt! I have been thinking about how to set it up. I think if I used that pvc/abs tubing and painted it with heat resistant paint, like what you use on breaks calipers and drums, it will be OK. I also have to figure out how to hook the tubing to this modual on the left side of the truck. I dont know what it is but there is a smaller tube going off my 3in stock air tube feeding this small plastic modual. I will work something out. Inform you with what happens alright?
Thanks alot have a good one.

I think to reset the PCM, speed tweaks says to turn the ignition on while the neg cable is disconnected for 15 secs. I believe this is just to use up any electricity in the system. I usually tap my brake pedal, but I assume just opening the door/hood would do the same. There can be no effect of turning the ignition on when there is not power to the system, so it may just be to use up some current stored somewhere. I have a 9" K&N and I believe the exit is 4" so mine might be too big for a homebrew, will have to get an adapter. We'll see.

Hi Rick, and anyone else who cares,
I just finished my home brew intake system, well mostly. I bought a 9in K&N cone filter. Used 3in PVC pipe with a 90 deg elbow. Hooked the K&N to the front end of the air tube. Used the stock yube's air sensor fitting to plug into the computer, and hooked the rear of the air tube to the stock air box assembly. Cleaned everything up real good and removed the old paper element.
Roused the 239 monster and started her up. sound out of my Flomasters is definitly deeper. Sounds nice. After letting it run for a while, and starting in numeras times, I took her for a drive. Noticed right away a lot better low-end torque. Hp seems to have increased too. She actually has more torque passing on the highway too. Very pleased with that...
All in all, seems to be the best engine mod I have done so far. Still need to make a heat shield. Any comments? Thanks to all of you, esp. Rick, it went really smoothly. Thanks alot guys

I have a 2001 Quadcab 4.7 and would like to know if anyone would have an idea on what the payback would be for a home brew intake and 180 degree thermostat? Is this enough of a mod to notice a differance in performance, I don't want to get fancy with the exhaust right now. I'm not sure if this is worth doing if it will be my only modification?

Joe, How did you connect the hose that plugged into the top of the stock air filter box? Does it hook up somewhere in the pvc tubing. I seen some picture but I don't know if they were of a 2001.

Phil, my truck is a 1990. I am sure your 01 has a different stock intake on it. I took the rear end of the PVC pipe and used a 3in rubber pipe joiner which connects directly to the stock air box. The only other hook up had to do was to the computer. And I rigged the PVC to run just infront of the computer air sensor. Used the stock conector and clamped it to the PVC. Hope I helped some. But a I am still sure that your truck differs freatly from mine.
Good Luck... Joe E.

Phil, do you mean the crank vent? It runs off the side of the TB hat? If you keep the hat and connect your pipe to it with a fernco connector, you can just leave the vent attached to the hat.

If you look at the picture @ http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=596162928 you can see a hose going into the pvc tubing from a hose connected to a connection at the engine. If you disconnect this tube close to the engine and put in a crankcase ventilation filter, Would you have to drill a hole in the pvc tubing and connect it thers?

I bought a 2000 sport with a 4.7 2 days ago! And am frantically looking for mods already. I will be putting a Z pipe on this weekend thanks to this thread. As far as PVC is concerned, I am an irrigator so I work with PVC every day. Regular PCV cant be used with hot water because it is only good to about 70 - 80 degrees. There are other types of plastic pipe that can be used but are more expensive. Worst case is it warps and breaks a seal at a joint letting unfiltered air in. But Im sure that some high temp paint or thermal tape which is used on home A/C vents (what I will use) should prevent any temp problems. Im not as concerned about extream cold temps because im in Texas, so no opinions there.
