P5 and cold air

[MrJoel]

I have been looking into intake options and I have some questions. My main concern is the issue with water and cold air intakes. AEM has the bypass for their CAI but they don't have a CAI for the MP5. Injen has A CAI for us but since it is one tube there is no place to mount the bypass.
So has anybody had any issues with water really getting up behind the bumper.
And wouldnt a oil treated filter really stop water that splashes onto the filter fom entering the intake system?
The only other option seems to be the short ram system but that does not help with the air temp issue.

What do you guy think? What are you runningfor you intakes?

No matter if you get the AEM or Injen you will usually need to cut the pipe for the bypass valve. I have had both intakes and prefer the Injen over the AEM. All you need to do is get a valve and install it on either make of intake.

i've been looking for an intake too...i've been talking to AEM...they said they have no immediate plans to make a CAI...unless we all petition for one maybe...in which case i would go for the injen...

based on some of my friends cars the AEM cai works better then the injen...but the injen is still really good...

as far as water goes...i thankfully live in az where water is not a big problem...but with intakes getting a little water in the intake is inevitable...which shouldn't really cause any problems...however...it's when you get into deep water that you will run into trouble...my bro doesn't have a bypass valve on his AEM and it's fine when it rains...just don't submerge it in water...i can explain more if you have any Qs...

 

[Sir Nuke]

I have the Injen CAI.....if you look where the filter really is...you would have to do one of two things to get enough water in there to do any damage....either one...be stupid enough to drive your ride through standing water that would certainly come in your door if you opened it...or two...have someone in front of the car with a 2 1/2 fire hose blasting it...

HOWEVER...for those that want to add the bypass valve...what you do with the Injen to install it WITHOUT cutting the pipe...is for starters you need to ensure you have the correct size...and you install it in front of the MAS ...INSTED of the red hose for the connection form the pipe to the MAS. THEN there is no pipe cutting required. Seen it done.....worked like a champ.

The Injen looks really sweet...all that polished Aluminum...and if by chance your car is RED....well all the soft parts are bright red...it only adds that much more to the engine compartment of a red car.

Sir Nuke...question

Being one of those "never can be too sure" people, I'd like to throw on an AEM bypass. My injen is on the way (separately) and I need to order the bypass. Could you tell me what the diameter size is to put on the Injen (2.0 L) ?
Thanks!

I don't want to trust my memory...and I am now at work and do NOT have access to my car or my STOCK system....all you need to do is one of two things....you can either wait till you get your INJEN and just measure the diameter of the pipe...and get one that the INSIDE diameter of the ends is that size....or go out and slip off the intake from that side of your MAS and measure it there....either way you will get the same measurement. Just ensure you specify the size you want when ordering it from where ever you get it from.

thanks man, I appreciate it

Waste of money

Let's stop and think about this for a moment. Are you planning on driving through any water that is more than a foot deep? No? Then what's the use in wasting $50+ for the bypass valve? I've had my CAI on for about 4 months now an I've had no problems. As a matter of fact, this past weekend, it was raining so hard here in the DFW area that there was localized slooding everywhere. I drove through most of it with no problem. There was only one spot that would have come up past the bottom of the door, but was I stupid enough to go through it? No. So I guess the moral of my story is, anyone who drives through water that deep deserves what they get. BYPASS VALVES ARE A WASTE OF MONEY. But if you really want to waste your money, feel free, I just thought I give my opinion.

slooding = flooding

Damn I cant type today.

Custom CAI

I made a custom (getto) CAI by removing the intake resonator, and plugging up the old hole in the air box, and cutting a new hole in the side that faces the right side of the car, I cut out the chunk of gold looking metal that holds up the radiadiaor fluid resivour, relocated it, and ran a 3 inch diameter PVC pipe to a 90 degree angle piece down to another pipe that runs all the way down THROUGH the plastic bottom peice benith the car. The pipe sticks out about an inch and I covered the end with some screen to keep any large rocks or other stuff from getting sucked it. I also angled the tip of the pipe so that at freeway speeds air will push right into it. All this cost me about 10 bucks at the local hardware store, and the car dose seem more free revving. I also have a K&N filter panel. sense my intake is RIGHT by the ground water is a big issue for me, thankfully all I need to do if I expect rain or a big puddle is pull over and yank the long section of pipe out so that way the water would have to jump about 2-3 feet up to get in the intake. I'll post pics soon for anyone that cares....

 

[scott42]

Ben, so you are saying that you are 100% sure that no water, if driven correctly, could EVER make it to a point where it could cause damage?
I'm a big fan of piece of mind, because when you think about it, would you rather spend $50 bucks and KNOW that nothing will happen, or not; and always have the possiblity of a non-warranty covered mishap occur?
I've already lost most of my hair...I just don't want to help it along unnecessarily being worried about engine seizure...

Ben, I have tried to make this point time and time again....some people just want to be SURE!! LOL.....once you go to install the CIA....you will get a real first hand look at where that filter is....and THEN you will understand why we tell you its not something you should waste you money on.....

OH.... SCOTT42....the instructions that come with the Injen prettu much SUCK....however....if you will go to Protege5Online.com and find the Injen Install tech article....there are some VERY helpful hints there and actually a complete procedure for the install that will save you a TON of time if you follow them.....point in case....the Injen instructions tell you to REMOVE YOUR FRONT BUMPER!! get real! you do NOT need to do that...and the instructions I just mentioned tell you how to do the install with out removing it.....piece of cake!

oh yeah...and Scott...if you STILL insist on getting the AEM bypass valve....if you go straight to the AEM website...they are only $38 there.

 

[big_ben]

I am 100% positive Scott. I not trying to make fun of anyone that has bought one or is going to buy one. When I read it for the second time it sounded like I was comming off as an a$$hole. I'm not trying to be like that. I'm just stating my evidence backed opinion. Do you know how much water your engine has to ingest to crack the head or blow the head gasket? IT IS A LOT! Not to mention that your car has to be submerged at least 2 feet in water. Do you realize that is almost past your knees! Like I said, if someone drives through water that deep in a car and not a truck, you deserve a cracked head. I wish I had come up with the gimick of the bypass valve. I'd be rich from selling the public the horror story of pistons bursting through the hood of their cars.

Thanks for the feedback

Hey guys I really appreciate all the info (especially the instructions warning Nuke!) I don't think you were being a jerk at all ben, I've read most of your posts and respect your opinion (You too Sir Nuke), you seem to really know what you are talking about. That's why I asked. Again, this place is great for this stuff. I'm really a rookie when it comes to this stuff and its good to know that everyone is so free to volunteer information.
Thanks again guys.

 

[Sir Nuke]

SCOTT....something else....if you do NOT reset your ECU its possible that you MAY get a "CHECK ENGINE" light...or at a minimum you may have a rough idle for a while till your ECU "relearns" your set up...

this is something else that NONE of the instructions tell you to do....so.....when its time for you to do the install....

DISCONNECT THE NEGITIVE TERMINAL OF YOUR BATTERY!! then get in your car and mash the breaks a few times...this discharges a few capacitors in the system....THEN install the system....hook the battery back up......start your car and let it idle for about 10 minutes...and you are all set...

 

[scott42]

thanks Nuke, once again!

Anytime bud, that is what this place is all about....helping one another.....

Couple of follow-up questions here on the Injen CAI... first, what does MAS stand for and if I didn't know what it stood for am I best not attempting to try to do this install myself? Is there any drilling required for installing it on an Auto? Also, will the Injen have any effect on warranty or emissions inspection? Thanks for all the great advice you guys provide!

MAS = MASS AIRFLOW SENSOR, the thing with the blue dot on it

no it will not void warrenty unless you hydrolock your engine, the dealer will blame it on the CAI (which they did not make/install) and that is your own fault and you will have to pay for it yourself

affect emissions? no
