Cold Air Intake

[jeenysrider07]

SO i Ordered a CAI off ebay and I have been reading on here alot and now I am worried about hydrolock. I found the aem air bypass valve on ebay for 50 bucks, which seems alot. I also found this and I was curious if anyone knows if this is just a filter or what? http://cgi.ebay.com/ebaymotors/2-75-Cold-Air-Intake-Bypass-Valve-By-Pass-Air-Filter_W0QQcmdZViewItemQQ_trkparmsZ72Q3a552Q7c39Q3 a1Q7c66Q3a2Q7c65Q3a12Q7c240Q3a1318QQ_trksidZp3286Q 2ec0Q2em14QQhashZitem380056910429QQitemZ3800569104 29#description


Sorry dont know how to put a link on here, also sorry for the newb question.

[jeenysrider07]

Well i guess i got the link on there.

unless you drive into a small pond.. dont even worry about it.

I've slapped a water puddle that was a good 2 inches deep traveling at around 25 - 30 MPH in the most horrifying rainfall i've ever witnessed in my life.. and yes my intake did suck up water..

all I had to do was park the car and let it dry and it was all good.

[CactusWill]

Thats the part you're looking for. $10 plus shipping, thats a cheap insurance policy.

[jeenysrider07]

Ya for ten bucks its worth it, well 50 is worth it but if thats what i need i am ordering it, cause i am worried about winter. Does any one else have some input on this item?

...................

I use a CAI, driven year round, I've been through absolutely terrible rainfall even for a trip lasting 5-6 hours, hit huge puddles, etc.

Realize that in order to suck up water into your engine, the end of the intake piping must be completely submerged in a pool of water and remain there long enough for it to suck up a massive amount through the piping into the engine. So if you regularly drive through 1.5 feet of water or however low the end of your pipe is, get a bypass valve.

this, or even sitting in a non-puddle area and rev it a few times (or just sit and idle a few minutes)...sure its a little extra wear-n-tear, but it burns off the residual moisture.

[Midgear]

^^^ your intake piping does not have to be submerged in order to inhale water up through the throttle body. simply splashing enough water onto the filter is sufficient enough to cause it to suck it up.. I've done it before- and I stalled right in the middle of the road.

be advised that this was extreme conditions.. pissing rain and my car barreling through a 1" - 2" deep puddle of water. driving in the rain will not effect it.. getting it drenched in water will.

[Redog]

I only run the CAI on the track, all the other times I run the WAI.

I have a CAI, I just convert it :p

[[ion] C2]

@Midgear: impossible.. did you take off your intake piping and find water inside it? your water splash may have hit electronics instead. if you sucked up enough water to kill the engine, you've likely done some damage, as water is hardly compressible and that force gets exerted on the piston/rod/rest of engine. no way you sucked up enough water to cause an issue like that unless your filter is chicken wire fencing and you don't have a fenderwell liner and thus the tire is throwing every bit of water onto it.

is your filter oiled? oil + water repel each other. my filter was slightly damp after my 5 hour drive through torrential rainfall and massive puddles, without any problems.

... why

[Midgear]

I too fail to understand how the water reached the throttle body.. but there was certainly water inside the intake tubing.. I took it apart.

were talking acorn sized rainfall and road ways that were turning into canals.. like I said before- extreme conditions.. the intake filter -was not- submerged.

[[ion] C2]

same with me and i have forced induction, so you'd think if driving through hardcore raining conditions would affect you, it'd definitely have affected me. i definitely nailed some huge puddles and hydroplaned quite a bit on the way back from indiana.

then again, i plan to spray a 50/50 mix of water and methanol into my intake. the water cools down the supercharger and is vaporized by the time it reaches the cylinders. which is why if you had liquid water in your engine it would have caused some epic damage.

unless you wet the sensors in the throttle body and it didn't like that and it died. people have that issue with spraying meth/water before the TB sometimes.

[Midgear]

Mabey that's what killed it.. wetting the sensors and crap.. but poppin the intake tubing off and seeing water in there like that.. figured I just sucked up a bit of H20 into the engine and it took a shit in the middle of the road-

[jeenysrider07]

i dont think i would get water in there, but for ten doll hairs what the hell, Better to be safe then sorry

[kwhauck]

wet sensors aren't gonna hurt anything, i regularly hose off the engine at bandimere for a speedy cool down between runs and never have any problems.....

[Midgear]

I hose my engine all the time with a high pressure sprayer.. we're talkin about sucking water up through the intake and straight into the throttle body lol

[kwhauck]

yes but your last post you talked that wet sensors may have killed the engine, hence my post.......

[Midgear]

yes but your last post you talked that wet sensors may have killed the engine, hence my post.......


[ion]_C2's post is what led to my post.. lol

[kwhauck]

so ions post led to yours which led to mine, which you responded to, with my response which has brought us to the current post........lol

[Midgear]

so ions post led to yours which led to mine, which you responded to, with my response which has brought us to the current post........lol

affirmative.. lol

[[ion] C2]

externally wet sensors aren't going to do anything, i was talkin about the inside where the actual sensing part is lol people have killed their TPS sensors that way or the IAC or something and that causes the car to die

[jeenysrider07]

I was just looking at that bypass valve and it says 2.75 in that isnt going to fit is it? i have a 3400 btw

[[ion] C2]

well how big is your piping...? *facepalm*

[jeenysrider07]

I am not positive i am at work but im guessing 3.5 in if that sounds right, i havent recieved the cai via ups yet. but it said it fit 2003 3400 alero, but for the bypass only being 2.75in i guess i will see when it gets here.

[CactusWill]

I need to get a bypass like this even with the stock intake. Almost lost my motor a couple times today, with all the rain we just got in FL. By the time you realize how deep standing water is, its too late. Oil light came on, I stopped and disconnected the intake hose from the air filter so it wouldn't take on any more water, got home and drained the crankcase and the water had made it into the engine oil. I think shes ok now tho.

[[ion] C2]

so tell me, how did water get in the crankcase and in your oil system if you sucked it through your air intake. lol

[CactusWill]

Ask my ecotec. Maybe he'll talk to you but he won't talk to me :(

washes down the cylinder walls..... Goes through PCV tubing...

Quick question: I want to get cold air for my Alero, but I've been told I would have to replace the whole exhaust? Is there any truth to this?

nupe...

[Nate's Alero]

:lol: Quick question: I want to get cold air for my Alero, but I've been told I would have to replace the whole exhaust? Is there any truth to this?

umm no? just get a CAI and install it....it would help your alero breathe if you got a new exhaust with a high flow cat and muffler....but its your choice

[-Alero-]

you would be pretty god damn suprised how fast water will go from a liquid to a gas in that combustion chamber

[jeenysrider07]

i finally got my cai today i tried to add a video but i dont know how it wont let me. But anyways heres soe pics

[jayson_waltz]

looks pretty good, but that looks like the ebay filter. you should def. replace that with an AEM Dryflow or a K&N sometime, they are lots better quality.

[jeenysrider07]

ya it will be replaced but it will do for now

[Midgear]

sounds bad ass at WOT doesnt it.

[jeenysrider07]

wot?..

[Kilroy]

Wide Open Throttle

[jeenysrider07]

thanks yea it does I love it it sounds like a beast

[darksobsession]

what's that round filter thing in the first pic?

[AlbinoMonkeyRat]

lol it's an inline filter

[darksobsession]

lol it's an inline filter

doesn't that impede the airflow? why a second filter?

[meadus101]

go read from page 1.

[darksobsession]

go read from page 1.

i did, but the link doesn't work. is the inline filter to trap water?

[digital0129]

i did, but the link doesn't work. is the inline filter to trap water?

It stops water from being sucked up into the intake. Its like having a large hole in a straw, its impossible for the water to enter the engine this way.

[worknprog.99]

i have a cold air intake fender kit in mine and where the kit goes water almost cant get to it if you got the same one......so like someone else said unless you ddrive through a pond you will be ok lol

[darksobsession]

everyone says the sound is louder, but i can't tell. what's is supposed to sound like?

[ALERO81]

I may be dumb here ...but what is the 2nd filter for the one by the tps sensor ?
would it not just suck in most of the air from there ? 1st time I have every seen that ?

[bratch15]

Wow...People really don't read the threads from beginning to end.
