pvc intake piping...
Damn sorry to hear it bruh. But she had insurance right?
LMAO. ALL HOMO!
3" piping. I didnt use any rubber or pvc elbows at all. I just connected both ends with a "midpipe" cut so short that it isnt visible at all. All you see is the ends attached to each other somehow. People thought I used glue. Out of all the experiments I've tried (2.0, 2.25, 2.5, 3.0) the 2.5 seemed to take the least amount of tq. You can almost say it was balanced. 2.25 was the smoothest and 3.0 was the loudest.

I was parked, woman got into her car, started it, popped it in reverse, didn't even look back and just hit my car. It's not too bad, I popped out most of the dent. Driver outter tail is pushed in a little and bumper is scratched. Whatever..
She had insurance but I'm at fault since I was parked in a fire lane so I didn't even bother. No biggie.
It almost looks like you cut that piping off a y-pipe lol. Got any bigger pics?

Fcukin sucks. Best of luck with the repairs. Hey now maybe you can finally install those ricer altezzas you've been dreaming and drooling over lol jk.
These are the only pics of an intake setup I have but I can definitely get them bigger. The url I copied wasfor the thumbs of each one which is why they're so small. Thing is my lil cuz left and he logged outta Phtobucket. Won't answer his phone right now either. Illl see if I can post em up tomorrow.

But definitely get some bigger pics up.
MAF adapter $6
PVC pipe $12 at the most. Bought a few extra in case of inaccurate measurements and in case i wanted to route differently.
Rattle can $5
Total of $40 give or take a few.
I had this idea many many moons ago.. But considering all the research that has been done and dyno's and finding that the stock airbox is best, i didnt bother.
Personally i think all of the issues with our intakes that we make not working has to do with the calibration of the MAF. And you can quote me.
As for needed tools, all you need are your basics: Screwdrivers, pliers, strong scissors, possibly zipties, oh and a hacksaw or what have you to cut the PVC. DO NOT use PVC adhesive to attach the pipes together. You dont want that **** to screw up the MAF if it does reliquify or worse, getting into the IM.

on my old SHO i replaced all the stock piping with aluminum tubing but still used the stock box with a K&N drop in instead of an open filter. The airbox opened right into the fender so it was basically a cold air intake. Ive been thinking about doing this on my maxima.

View post 48 for the materials you would need. The rattle can is optional. I forgot to add a hose coupler to that list but a previous poster asked for pricing so I didnt list it since I had that laying aroung in my garage. Or you can do what I did with my 2.25" setup and just use the stock rubber tubing, cut to appropriate length, and clamp that onto the maf.

^ This pictured setup was only good for its roar. Out of all the setups I've tried, this one lost the most tq due to the reduction of velocity with the larger diameter of the piping. But the science of a hybrid intake gives you flexibility of switching from CAI to SRI to both even. They have blockoff plates for the pipes. Go with a smaller diameter pipe and you'll net much better results.
The pipe that hooks to the MAF is basically a y pipe. It came like that except I had to cut it down to make it fit.

^^^lol, i have to agree...
^^^what size was the pipe, 3in?...
true...
true, like i said i didnt have any problems with my civic. and i forgot about the intake running close (closer) the the header...
the way i see it is that i was just trying to find other ways to get "more" performance out of a non metal intake. i have a metal intake right now but its just a SRI. i figured since pvc isnt metal that it wouldnt heat up as much as metal intakes would. it has nothing to do with not being able to afford a metal intake...
that does make sense and probably work better, but when i put my metal intake on i throw it away 
^^^what size was the pipe, 3in?...
you should try using the PVC and seeing where it leads bro. If you used a similar setup on your 00-01 civic, it should be fine. Our exhaust manifolds aren't really close to where the piping is going to be anyways. In civics, they usually go down and sit right by the headers. Oh yea i forgot to mention that the melting point of PVC ranges from 100-260 degrees Celsius. if your really worried, you should heat wrap it and it wouldnt get extremely hot, plus that would hide it so nobody would even know its PVC lol.!!
do you have links to these so called "research"?
during idle the velocity of the air going into your engine is quite slow/low.
i'm not going to sit here and argue with you guys that can't afford a metal pipe and two couplers. it's your motor and your car...i'm just throwing some warnings out there so you don't come back saying that there's a mysterious coating inside your intake manifold and it's causing weird issues with your car.

Wow, homemade PVC intakes look so cheesey. I wouldn't do it unless my stock airbox was cracked or something.
Besides, how can you get colder air into the engine through a cone filter inside a hot engine bay?
And yes, PVC piping does release nasty chemicals when heated. Electricians use a hot box to heat the pipe for bending.... I've done it many times and the fumes are pretty bad. However, I don't think it would get too hot inside the engine bay, definitely not to the point where it gets floppy and you can mold the shape.

^ That setup, yeah, all 3". Either 2 or 2.5 would be better in regards to a more minimal loss of tq.
The ypipe is a PVC ypipe and was basically included in the total of PVC piping needed.
The block off plates I'm referring to (I didnt know what to call them) are just plastic pieces that you put in the tube to close it off. Theyre built for the pipe so fitment isnt an issue. They should be located on the same rack the PVC is on. Basically, you do have to take the whole thing apart but only by the filter. Ill see if I can find some and take pics to show you wat Im talking about.

Curious as to what you guys ended up doing with your intakes.
Im in here again because I might have to run a PVC midpipe to pair with a PR CAI tube that runs down under the fender. Pics of progress will be posted.

Have you seen how many people have SRI's on their 4th gen? Don't hate, not everyone is rich.
I'll post the link!

Ahh great point..this pictured setup was when I ran the IACV vacuum with a breather and that didnt work too well. Ran it remote for awhile. Afterwards as a modification, I added a small midpipe post maf and hooked up the hoses via drilled holes and jbwelded shut. Dont have any pics of that setup.

i'm thinking of making a custom cai but out of pvc piping. yes it sounds ridiculous but think about it, intakes are made of aluminum. aluminum is stil some type of metal, and will heat up under the hood (not as much as most metals but still heats up). pvc doesnt heat up much (or at all) when heat is applied. so a cai intake made out of pvc will hold and let air travel through into the throttle body with the air being the same temp as the air outside of the engine bay (which is the purpose of the cai). i was given a pvc cai years ago when i first got into imports, and to be honest it performed a bit better than a AEM cai (which was probably the only aftermarket intake make in 2000 2001 aside from iceman).
so i guess what my point for this thread is, your opinion on this. yes it make look a bit odd when the hood is open but my thing is performance over looks...

PVC as intake piping can be a cheap alternative, but if you are looking for performance, stainless or aluminium is the way. You have misconception about metals as intake. PVC will not keep it cooler, it will do the exact opposite. PVC is a composite of plastic and rubber, it will soften around 60 degree celcius compared to metals which wont soften and will keep their strength. Also, PVC since it is made out of plastic, will absorb heat and will have difficulties cooling down, it stacks heat and wont let it go, thus will it only heat up your air going into your intake manifold. Aluminium is usual the best overall, cost wise, weight wise and also heat heat release capacity. Aluminium wont keep heat, the air it will get through it will cool the piping contrary to PVC.
