Making my own Cold Air Intake

[TheMcCumbers]

Hey I was looking around at some cold air intakes online and I decided that the prices on these things are horse shit. I was thinking about making my own out of some flexpipe and just buy a filter seperately. Also I was thinking this would make things alot easier when I got to put RAM air on it. Has anyone ever done this or know anyone that has done this, because it sounds easy but I am sure I am missing some major part of it. That is how shit usually goes with me.
Any feedback would be appreciated guys.

depending on the flex pipe you want to use, the ridges on the inside of the tube may cause more turbulance than the stock system...and it could kind of flop around in there if youre not careful when mounting it. I cant imagine anything being much worse than the stock intake on these trucks, but you may not really get much more if you put the ridged/rough flex pipe. Ive heard of guys using PVC piping for homemade intakes, but even then you might be running into trouble with heat and such. Also keep in mind your MAF sensor has to be somewhere in the intake tube too. I got my intake off ebay for $90 (with a K&N filter), which is cheap compared to the full K&N intake kits.

good luck,
AJ

wat about the ones from autozone?

[Zeeke98]

Autozone? THE APC, aka All Pieces of Crap ones? I've heard worse things about the APC than I have about e-bay ones. PCV pipe won't melt underhood unless you're laying it on your exhaust manifold. I had a friend that made one from PVC and I had used some to make a cold air setup with a K&N cone filter on my Olds Calais. The problem with just piping and a filter is you still suck in hot air from the engine compartment. You need a heat shield or box to keep the engine air from getting sucked back into the filter.

[What?]

ebaaaaaaayyyyyy

Made a custom intake with PVC pipe before, if you do this make sure you get clue to put the pipes together, water got in my engine...bad stuff. If U know anyone that welds or you do, just get some pipe and make your own, that is what I am planning on doing.

the other easy way to get a good intake is go get it custom cut from a exhaust shop, that is cheap, use 3 or 3'1/4 pipe. get it bent as so it goes into the vent from you factory airbox mounting hole( provived you make it larger) it is a true cold air intake, remember to wrap it in insulating wrap.

Hell yeah man, I never would have thought of that... Hell yeah.
I think I got me a new weekend project.

Any thoughts on attaching it/fittings for it though?

[GETNLWR]

get one of those cheap miniature air filters for the top of your valve cover, and drill a hole in it for you intake temp sensor thingy ( i think that what it is. its right after the air box) and use the factory grommit it should work great, the ither option to doing a wrap is to pay a place to powder coat it. shouldnt cost more that 30bucks for the coating and you can make it what ever color you want.

if you're gonna be cheap use ABS piping instead of PVC. abs is the black plastic. doesnt look as ghetto.

[TheMcCumbers]

On the thought of having it bent by a machine shop... what about the part that goes over the fan? could I just bypass that and put the inatake on the other side of my engine, or does the fan have a part to play in the induction of air? Because if I put it in the factory position then that is gonna be a hell of a bend to put on a peice of pipe.

my intake is pretty cheap, costed me 20 bucks... went to autozone and got a 3 ft flex intake tube, ran that from the throttle body down between the battery and the fan shroud.. I tend to run 15 degrees warmer then outside temp, and this is without heatwrap..

[GreatWhite00]

I just spent the money on the K & N.

[box12360]

thats what i did and useed that flex wrap and bought a k&n air filter. I cut on the stock box so it could suck more air in when u mash on the gas and it works probly just as good and a $200 one and spent 50 or 60 almost all of that was on the k&N air filter.

[Purplepimp]

I have made 2. First one was good, used drainage pipe and spray painted it. I had to demolish it to get it out for smog test but I make a nicer one now. I used the black pipe and right now it is just a cheap autozone filter but it still is better then stock. You can check out my cardomain page for pics of it.

The flex pipe I dont like cause it is rough inside so I dont think it helps the air flow. And it you have problems with it moving around, make a bracket from the fan shroud that holds the intake.

If you want an easy way to bend pvc, or abs...

Get a big pot and fill it with clean sand, heat it up to where you can start to feel the burn when you put your finger in it... Then fill the peice of pipe with sand, and bend it however you want...

[s-10kid]

i have the stock filter but with the k&n inside of it. would it be ok if i like cut a hole in the stock box?

[Zeeke98]

I did this on my 92 Blazer. I pulled the bottom of the filter box out and took a 1" hole saw and swiss cheesed the sides and front so it could pull more air. It might help a little on the 2.2 but it's such a convoluted setup nothing short of totally replacing it is going to help.

[ACE2790]

I built mine out of PVC and painted it black. then bought a air filter. 38 bucks total spent. Hardest part i had was connecting the pipe to the TB, but its all good now.

[box12360]

Man on my stock box i pertty much took the whole frount of the box out and i could a pertty good change i think the stock k&n filter is the way to go with the stock box b/c the air is pushing right where the whole is compared to an after market set up b/c it is father back and does not have to same induction.

Purplepimp vbmenu_register("postmenu_2337594", true); i dont think it really matters about the inside of the flex wrap b/c the hole that the air is going through is huge and i dont think the air flow is strong enough to where that would really matter.

I just cut the whole bottom of the airbox off just past where the box sits on the little bolts so all I have is the filter sitting on a little frame. I am thinking about getting some tubing bent and then having the inside polished. I will let you know how it turns out.

[truckinjeff]

One question, What is the difference between ABS pipe and PVC pipe, other than the material it is made of? Which one can withstand higher temperatures best?

[zibzer]

i made mine out of pvc pipe.. worked good and looked decent.. but i took it off.. i couldnt stand the noise

[Indigo2K]

Or you could just by this one:

Does the filter ever get wet? Because it seems to me like it could and I think that would cause some problems.
