Trying to decide whether or not I need to invest in one.

 

I bought one with my AEM CAI, and I decided not to install it since you have to cut the intake and put it in that way, its not a simple bolt on.

 

well i just blew my motor from not havin it....so i think ill be investing the money for one into my next cai......

 

already had a recall from AEM, apparently the rubber pieces were falling off and getting sucked into the intake!!

 

Dont you have to like practically drive underwater to blow your engine or is it really that easy?

 

ttt

 

well like i said..... i was just goin through a puddle... although my splash gaurd was kindve missing ....... but i had gone through them b4 and never had any problems.... :: guess someone was tellin me its time for the
DOHC

 

Shoot that sounds like a symple bolt on to me. Go to get a plumber and borrow a pipe cutter. You will get a better cut than with a sawzall. Then install the bypass and rip around town.

It is worth the protection.

 

I know your supposed to put the bypass valve towards the top of the intake, but would it reall ymatter if you just put it in between the two main pipes? Then you wouldnt have to cut anything, and itd be easy to install

 

I was thinkin of getting the bypass because I blew the motor on my GSR last year in FL in a huge rainstorm. I dont think I'm gonna get it though. Me and my friends just went to Seaside NJ and there was flooding when we were about to leave the next morning. So we all just pulled the AEM's off the TB and went through whatever deep(1ft+) we had to. No problems at all. Just keep a screw driver in the car.

 

That sounds like a lot of work. I would do the upgrade and not worry about it. I think my wife is looking to score an aem intake.

 

I think just to be on the safe side - it would be wise to get one.
Mine is in the garage waiting for me to get home from work this weekend so I can put it in!

I also think it kinda depends on where you live and how much rain or potential flooding there might be in your area!

peace

 

how much are they?

 

Thats what my friend did to just drove trough the puddle (no inner fenders though) and it bent a rod in his 'Teg. They had an article in sport compact(i think) about them and they were testing them on the owner of AEM's NSX. They had the filter in a fish tank and at 60 mph the water never got close to the motor.. It was interesting.

 

no need to worry about puddles. you should have a sticker on your intake pipe stating the depth of the water before engine go boom

 

Yeah but there is always that one situation where the intake can do something and screw up your motor.

I think the bypass is $40.

 

Although the by-pass valve costs a lot of money for a valve and it would take a while to install, I think it would be a worthwhile investment...in the long run, it would save (if you have it) your CAI from damage...

Actually you are the only one who can answer that. If it is worth it to you and would make you feel better then purchase it.

But in my opinion you don't really need it. Another easy $45-$50 for AEM to pocket. Not saying that it couldn't happen, but it would certainly take more than a puddle to hydrolock any motor. And if your splash guard is missing then, thats all your fault (its there for a reason).

Back in the days when I used to be younger and way before I was even here, my dad owned and operated a partnership with his friend Tom. They owned a body/performance shop. He shared an old tactic used back then, "which was to actually pour a little water down an open carburetor to clean carbon buildups off of the head and pistons". A little puff of stuff out the exhaust pipe and still ticking. So just going to show that a little water in an engine isn't going to hydrolock it.

Even the sticker on the intake states if anticipating driving in 16"'s of water (less if vehicle is lowered) remove CAI intake system. So just my thoughts on the topic.

 

Oh yeah, it would probably help if people didn't try to drive wide open in the rain too.

If you remember the article with the NSX and the bypass valve, it was a WOT run all the way up through 3rd gear. It took WOT to get the water to come up in the tube, and it was completly submerged.

My point is, if you aren't opening it up a lot, you aren't sucking as much air in, and in turn this weakens the chance of large amounts of water getting in.

 

Blew my motor without one. Small rainstorm, didn't see the puddle, 50 yards later a loud clank - goodbye #4 rod with a nice hole in the block. Several thousands of dollars later and 1 bypass valve (did not matter what it cost) I had my motor back. The bypass valve really works too. I have been riding down the road on a few occations and heard a gurgling sound which is the valve doing its job, back off on the throttle so the water will drain and everything is OK.

 

I have the AEM Cold Air Intake and the bypass valve installed.. it was only about 15 bux more ... Just make sure you mount the intake securly or it will bounce around and tear like it did in mine..

 

Did we help?

 

for sure, thanks a bunch

 

anybody else???

 

I have AEM CAI and I don't see the reason for having one after waht I seen about a month or two ago. I was at my local speed shop and the owner was doing a swap an his Civic CX hatch. He thought it would be ammusing to blow the CX motor for the hell of it and that is what we did. The motor had about 160,000 miles on it. We opened the hood and put some vice grips on the throttle cable in the WOT position and proceeded to start the car. Lets just say the car bounced off the rev limiter for 17 minutes and only blew because we diconnected the intake off the filter and sprayed water directly into it. We did this for about 4 to 5 minutes. When we first sprayed water in it (about 20 sec) the bogged down and we thought it was over. Nop, not at all. Then the car came right back up to red line and did this several times before it threw a rod throught the block. We actually had to spray water in the intake for about 1 full minute without stopping to get motor to blow. I agree with RedRacer when it comes to this subject because I am the one that talked him into getting the AEM CAI for his car. Just my .02.
