I sucked up water in my Injen CAI trying to get home. It flooded bad over here! I parked into someones driveway and I prayed that I didnt get too much water in my engine. I pulled out the spark plugs and cranked out all the water. It works fine now though, a very scary situation! Has this happened to anyone? with the Injen intake. My damn Bypass valve didnt do ****! I may need to get a splash guard.

 

Man I was so freakin scared! Another reason water got in so fast was because I cut out the front piece of the plastic fender wall. Right underneath the cone filter. (where the 3 screws you undo to put in the filter) I even made a custom scoop, from the outside right to the filter. The scoop got "curbed" out awhile back , so there was just a large hole on the bottom for some more air flow. But now I might cut 2" off the intake pipe where the filter connects, to raise the filter up a little more. Who ever has the Injen intake w/ the Bypass Valve knows that the filter is right at the very bottom. The filter practically touches the plastic fender. Well, i had a lesson learned and now i need to make a few adjustments!

 

i had a question- i just ordered(like an hour ago) the injen cai for my 02 lx b/c i got tired of seeing my ghetto intake ( short style "ram air" attatched to stock hose and the MAF and shoved in the little hole) i put a water bypass valve on right after doing that because i drove in a slight drizzle, not even actual rain, and my car all of a sudden wouldnt accellerate hardly at all. i live in waco tx and dont get a lot of rain, so should i put the bypass valve on the injen or not? will there be a noticable hp difference? any help will be nice

 

LEAVE it off!!! i am running the injen...the cars NOT lowered...I took some measurements....for you to get water up to the cone filter such that it will actually suck water into the engine you have to get the front of your car running through water a little over a foot deep....I don't know about you...but I will NOT drive my car off into water that deep....for any reason....I will pull over...turn around....find another way....or just park, lay the seats back and go to sleep if necessary.

The other member that hydrolocked his engine I know....his name is Patio...and yes he lives in houston.....his car is lowered about 2 inches...and ran off into some REALLY high water.....like a wake from another car washed water as high as the top of his headlights...and that did him in......

Personal opinion here.....ditch the bypass...and keep your ride out of high water....after all....if you want to go in for those activities.....go out and buy a 4X4 and jack it up.

 

I would have to agree with Sirnuke.. I have had my Injen on for about 17k miles, driven daily through an Oregon winter. I do not have a bypass valve or a splash guard and I have had zero problems with it.

 

ok, so no on the bypass.... another question- in the pic of the ingen, it shows the whole intake pipe as one piece- will i need to cut out a section to put in the maf and oxy sensor, or is it in sections?

 

oh yeah forgot to mention- sirnuke- my car is lowered 1.5 with the eibach springs- this wont be a prob? i was worried more about water and mouisture coming in through the front of the bumper

 

It's actually two metal pieces so you don't have to cut it for the 2.0L version

 

<<< the infamous one

ask me about bending shift forks too! :thumbsup:

the by pass valve will do nothing (easy way for AEM to make money eh?) UNLESS the filter is COMPLETELY Submerged, even then some water may still get into your motor, whether you spend 40 bucks or however much it costs or not.



<<cars in the shop

 

the picture you have seen or are looking at is the intake for the 1.8L motor....the 2.0L intake is two pieces..



see?.... :{D

 

NOPE no problem at all.....and when you get your intake...go to www.protege50nline and to their TECH section and get the instructions from there....they are way better than the ones from injen.

if you follow the instructions from Injen, THEY have you totally removing your front bumper to put the intake on!! geeeez....that is so TOTALLY not required....the other instructions tell you how to do it.

the total install took me about an hour.

and water is NOT going to splash on the filter coming from anywhere...its nearly totally inclosed inside the front fenderwell...NOT air tight..or water tight....but I honestly believe you would be hard pressed to be able to get the flter wet using a FIRE HOSE!!

 

Yep I have about 10,000 miles with my Injen living in norhtern Oregon as well. And it rains like a **** here. Although I think Oregon is less prone to floods just cause it does rain here all the time, and the roads are setup really nice for drainage and what-not. I don't think I've ever driven through any water yet that has been too much deeper than my 40 series tires.

 

Guess it doesn't really matter if you have a bypass valve installed on your CAI or not, if you go through a flood of water, you're gonna suck it up like Citizen did. So everyone who says it's not worth it are probably right, especially since putting it on will lower your gains that you might as well keep the stock intake.

 

First, don't drive through huge puddles. Second, if you do as soon as you hit the puddle and notice it's a big one, kill the engine. I mean dump the thing turn the key and put on the hazards. It may suck to have to tow or push your car out of the puddle but it's better than Patio's dilemma.

Alsom injesting very small drops of water into the engine will at worst lower the efficiency as it is evaporated upon combustion, but anything more than a few drops per cylinder and you could have compression problems. I would still get a splash guard of some kind. Build one from Home Depot parts it'll take ya an hour to make.

 

how would i fabricate myself a splashguard? and where would this be mounted? in front of the filter?
