i drive a 1998 2.4L cavalier and am having a little problem with intake installation.
once i remove the stock intake, i'm not too sure what or how i'm plugging the sensors into the new intake.
on my intake there is a tiny rubber hose connected near the end where the air filter is attached (which i am guessing is for the ait sensor?)
on towards the other end, there is a little pipe that sticks out perpendicularly from the intake pipe. my intake came with this L-shaped rubber hose with a metal piece at one end (is this for the pcv sensor?....wtf is the pcv sensor??)
do i just plug the ait sensor into the tiny rubber hose near the air filter and the pcv sensor (when i find it, guessing it's under the "expansion chamber" <-- the i mean factory compartment which the s-tube connected to) into the metal end that L-shaped hose?
thanks again, for any input you can give. where i live no one really works on their own cars and i'd like to start learning somewhere.
sorry, didn't mean to post twice. please feel free to delete the other topic.
yes the AIT plugs into the spot by the filter... so u have that correct...
the rubber hose u dont really need to hook up, u could simply plug that hole and add a breather filter to the other rubber hose it connects to... now the other rubber hose i'm talking about is located between the intake manifold, trust me once u remove all the old intake peices you'll know where and what i'm talking about... if u dont have a breather filter or dont want to hook one up, that's the hose u connect to the L shaped one you got...
kinda hard to under stand so i'll try to clear it up even more.... remove the stock intake peices, look down at the throttlebody and intake manifold, you'll notice a black hose inbetween the intake manifold, i'm not sure if it's attached to any of the stock intake but my wasnt it was kinda tucked down so i just pulled it up and attached it to the supplied hose and that would be the L shaped one you have, mine wasnt L shaped and it isnt in the same spot as yours but thats what its for... i'm not sure what its called....
hope that helps ya... but honestly you really only need to hook up the AIT sensor in the location near the filter... then your done...

1: Yes, the IAT sensor goes into the little one near the filter. Yes, the sensor in your picture is the IAT sensor. Be careful when you connect it though, the IAT is pretty cheaply made, and is very easy to break. They're pretty cheap to replace, but better to be careful and not have to go through the hassle.
2: PCV = Positive Crankcase Ventilation. It'll be pretty obvious once you take the intake off what needs to connect there. It'll be the only thing connected to the intake other than the IAT, and since you've already located that......well it kind of narrows it down.
3: Yes, that rubber hose should be pushed all the way down to the hilt to make sure it doesn't pop off.
Hope this helps.

LOL captaincarnage beat me to the punch. Damn, I need to learn to type faster.

thanks guys, it helped alot. (i'm gonna be attempting it myself so you helped clear up the things i was worried bout.)
but since captcarnage mentioned it, what's exactly a breather filter?
You can get them at AutoZone.

DO NOT plug the iat sensor into a rubber hose....
cut the metal nipple off and install a grommet in the pipe itself. the iat should be in direct air flow, not stashed away in a rubber hose or metal sleeve where its NOT in direct air flow.
page two of the post at the top of this forum has a walkthrough near the bottom.

how do i install a grommet? is it that bad that the iat sensor is in the rubber hose? because if i cut off the tiny rubber hose how can i clamp the iat.
but either way i'm still not sure how it'd even attach the iat sensor to the rubber hose..i was just gonna stick it in there (which i guess wouldn't be too secure.
ugh...
damn i'm having a tough time removing the stock intake.
i so far managed to remove the expansion chamber and found the pcv tubing which i could attach the L-tube (or maybe in the near future breather filter too.....actually does the breather filter attach to the pcv tube or the small metal portion on the intake?).
I removed the iat filter and S-tube, but am having a tough time removing the factory intake. i have removed the battery but am still concerned about taking it out.
i've attached some pics again too show the troubled spots.

you quote the FIRST TWO lines of my post, the the last line is prob the most important as it tells you how to do it and why you should....
Yes, you just pull the airbox out of that socket. There is a rubber gasket holding it in place, so it takes some work to get it out. Don't be afraid to put your back into it.
That reservoir you have circled just slides up and out of the bracket that's holding it. As far as where to mount it- just mount it to the firewall using either your adhesive of choice or drill a small hole into the firewall and bolt it up.

Sorry for the double post here (just call me post-whore, baby) but I forgot to mention something before I hit post (yeah, I know- I'm a dumbass).
Dam-it Muffins- I think one of us is misunderstanding the question this guy is asking, and I believe it's creating some confusion. The way I read it, he is referring to the drilled rubber bung up by the filter as a "short hose". Looking at the picture he posted, his intake has the IAT positioned up next to the filter, and the PCV tube down towards the TB. The hose with the metal tip is his PCV return.
Maybe I'm the one that misunderstood that, just wanted to clarify before the poor guy's head starts to spin and he goes nuts trying to modify his intake when the necessity of said modifications is in question.

yes event is right a grommet should be used for the IAT(misspelled in my first post)...
u need to remove the paper filter in the intake box and there will be screws that need to be taken out to remove that part... the clutch resovier(attached to the top of the factory air box by firewall) can be placed anywhere aslong as it doesnt move and isnt upside down... my buddy hung his on awire along his firewall, my car is auto so i didnt have to deal with that so i'm not 100% sure where u should mount it...
also there should be no wires and anything attached to the bottom of the factory intake box, simply take out the filter remove the screws and it should come right out...
u shouldnt have to take out the fuse box to get the air box out, once u get the screws out(unless mine was missing some) you can pull it right out... but once again maybe theres a diff between 5spd and auto, but i didnt have to take out the fuse box... hope that helps ya some more...
and yes the breather filter attaches to the PCV tube not on the intake...

it shouldnt be anything misunderstood.
to KISS with intakes (KEEP IT SIMPLE STUPID)
install the sensor the same way it was installed with the stock setup....
the obviously the sensor goes into the rubber pipe in stock setup... for an intake, the sensor should be reinstalled into the pipe...
this is simply why i directed him to the FAQ... page 2 of it, the bottom of the page...
its a giant picture sequence telling you what to do to install an aftermarket intake...
1) so that everytthing will be plugged back in and work normally
2) so that no codes occur
3) so people know where you put a breather filter and where to connect the iat sensor back into the tube....
if he wants to connect the rubber L hose on his new intake BACK to the crankcase, then he can do so.... however the IAT should be reinstalled back into the intake pipe and there are instructions with pictures to do so.

haha opps i didn't even see it. i think it probably thought it was a caption for your picture.
so thanks i checked out the FAQ.
anyway, due to being unable to remove the intake box and the sun being gone, i decided that my first attempt was over. so i put everything back in.
BUT now i have a separate PROBLEM!!. I attached everything, leaving the negative terminal of the battery last to connect. only problem is, everytime i try and attach the negative terminal to the battery my alarm goes crazy and i can't seem to shut it off. also as i touch the terminal to the battery, it creates a spark and that in addition to the alarm, it scares the hell out of me. it's the first time i've ever taken anything apart in my engine including the battery. so i'm really not sure what to expect.
anyway what do i do about the Alarm?!
all cool....
well def try tommorow.....
small hint, remove the battery completely.... reason on some cars theres a bolt that holds the air box in....
on others a clip is there...
as for the alarm, have your clicker thingy ready to turn it off....
so basically when you connect it, push the disarm button on the lil clicker thing.
also, that process....
attach negative
car alarm goes off
disarm alarm....
you;ll have to do that anytime you disconnect the battery
kinda becomes second nature after a while
yep. i removed the whole battery before trying to remove the intake box. for some reason i really think it's attached to the fuse box.
anyway, yeah i'll will hopefully try again. i need to think of a way to mount the clutch fluid to the firewall (first i must locate the firewall) and then mod the iat input on the new intake.
so then i have nothing to worry about when i'm attaching the negative terminal?...those sparks are common? haha i don't want to fry myself over a cheap intake. think i'll have to call CAA or something tomorrow morning so i can go to work.

The firewall is the wall at the back of the engine bay- it's what seperates the engine bay from the rest of the car.
If you connect the neg cable quickly and firmly it will minimize those sparks.
Same thing happens with my alarm- annoying yes, but not a problem. Just keep shutting it off until it stays off. I usually try to arrange for a buddy to come by and hit the damn button for me while I'm tightening the terminal.
And I promise it's not connected to the fuse box by more than a clip, you just have to angle it a little and wiggle it 'til it comes free.
I may not be the sharpest crayon in the box, but at least I'm a pretty color
sparks will occur whenever you touch a metal piece to a live power source to complete the system.
you can either get a clutch fluid reservoir thing or make one, or zip tie it to the hanger piece that you will see, LOOKS LIKE A HANGER, that the air box connects to up top....
air box isnt connected to the fuse block...
otherwise than that, dont be skeered to flex a lil muscle in pulling it out
