Air Intake

Ok got an idea for a New mod, now i have been looking at a new air intake and thought about the K&N but at 300$-500$ (CAN) a kit i thought i might just attempt to make my own, but i wanna keep the black rubber original intake hose so i thought i could remove the airbox and strap a cone K&N to the MAF sensor, but because its a flat plate with 4 bolts it in i think id beable to remove the whole airbok and flip the upper lid so its upside down and take about 3" off the end so its still can be bolted to the sensor but a cone filter would still fit without hitting the one end, now take a piece of PVC pip about 5" long that will fit snug in the whole wherre the sensor is and without hitting or wrecking the sensor glue it in with JB weld or something tuff and just Hose clamp the filter to the PVC pipe, now i havent tried this yet and i think it might work but if it dont ill be buying a new airbox and maybe a sensor but thats the cost of finding things out i guess. but if anyone else thinks it might work let me know or anyideas to help out thanks

i know there was someone here who used a plumbing flange to make an adapter for the MAF, that would work a lot easier. i think it was brenton??? i could be wrong.

i just ordered a kit made by air raid that costs under 200 US. all it does is replace your factory air box and puts in a cone type filter. it is only open where it needs to be and doesnt pull air from your engine bay.

your way may restrict the air flow a little bit because of the smaller opening that you will be creating. with the filter being open, you may have problems there as well with offroading and such.

your plan could work though.

The biggest restriction is gonna be reusing the stock intake tube. Because itz rubber and ribbed air doesn't flow as well through it as a smooth bore tube as seen on the K&N kits or MAC intakes and the like. If you were so inclined you could have a muffler shop mandrel bend you a piece of stainless and work from there with some hose clamps and silicone couplers. You could order a MAF adapter and bada-bing fairly cheep intake.

You know i never thought about that, i think the intake hole is 3" so if i got a 3" exaust tub bent to spec it would work pretty good. and where could i order an adapter, ive been looking for them and havent had anyluck finding one

the inside of the tube is actually pretty smooth and the rubber resists heat very well.

someone on here (sorry i cant give true credit to you) had problems with dirt getting in their filter because they were a low rider so they actually modified a plastic flowerpot as a shield.

Not sure where to get em off the top of my head. Someone on GE mentioned plastic ones being sold at auto parts stores like advance auto but I would think you wanted a metal one b/c the plastic ones have had a tendancy to break. You will have to fab up a support braket but I think you could find a way to do that with hardware store parts. Also make sure to clean the inside of the tube rather well, you don't want any crap in your motor.

i think its like 15 horses to the flywheel. you cant really feel a difference with it. it just helps with aspiration, if you will.

the stock tube should be fine, on the 4.0 it should move adequate air, and it is smooth on the inside of the tube. a flowerpot has been used before, i want to say baggededge did it, but i just used some metal ducting for mine and it worked well. if you want to do this on a budget id say keep the stock tube and use the flange to mount a cone filter to the maf.

i cant remember, i was hoping someone would have a link. basically you find some flange with a pipe fitting that fits your filter. then you trim the flange part a bit and drill the holes in the correct positions for the maf, fab a gasket, and bam, there you go

i think air ducting has a deal with a hole in the middle and a rectangular shield type deal that would work perfectly. you could always use the scrap cut off to help strengthen things.

ok heres the deal............i have a home made intake!!!!

heres how i did it.........i have no pics(yet) sorry

ok......
1. i went to auto zone and had a look around the apc section and there they have a square 3inch adapter plate for universal fitment.........or it maybe for a wide range of vehicles like nissan sentra/civic etc.....it has holes and slits pre-drilled

2. I then dremeled the corners off it so that i could use bolts and washers to hold it up to my maf

3. if found my self some bolts and washers and bolted it to my maf

4. Made a gasket out of thin cork to act as a good seal

5. got some aluminum bar from home depot cut and bent it to act as a bracket to hold up the maf (stops it sagging into where the airbox used to be)

6. found me a 3 inch filter and that was it

Oh and to give you some input on making your own tube to replace the stock rubber one...............dont bother..............i made my own out of 3 inch PVC plumbing pipe yea it was great for about half a day then the truck kept on cutting out and really rough idle with the nice little check engine light too

hope i could help..........sorry i dont have pics!!!! im working on it
