really?? care to explain? never had a prob here or for anyone that I know of.

I thought the need to tune after installing a CAI was only for WRXs?

I've had my Cobb installed for over 3 years now (no engine management whatsoever) and it has never given me any problems. The only thing I can think of that would go wrong is sucking up some water, but that's pretty easily avoidable.

i've had my Injen for 4-5 months now and no problems yet. I did reset the ECU though.

No problem with my CAI, either, except for some undue attention from the local authorities...

Well I made it through some Oregon rain and puddles with an Injen CAI. I had no problems what so ever. I was careful though too. I just pulled the CAI our for some cleaning and it was not too bad after 1+ year. A worthy mod, just be careful.

As for the tuning, that is on a WRX. Injen, AEM, and early versions of Perring/APS, caused problems for the mafs and sent it all to hell. I am glad that I don't have to deal with that :D

no problems since last feb. with my cobb cai...

Rule #1)

NEVER discuss car modifications with a Dealership!!!

(well there are one or two exeptions, but I dont think they apply in this case)

^^ that is by far the only rule you ever would need to know about modding.

<--asks my dealership about mods all the time. hell they sell deadbolt turbos. the parts manager has a beast of a wrx. they are a mod friendly dealership and also sell performance parts. gotta love prestige subaru in asheville nc.

Why would you PAY someone to install a CAI? It's a super fast and easy install. And no, you do not need EM for it. I would suggest resetting the ECU at least though.

And to iownaspec: yes, prestige is the ****. Those guys up there are wonderful!

not everyone is super knowlageble in cars so they dont like to risk messing stuff up

just find people in your local area to help you install one its not to bad

as holy said earlier no EM is needed, i have intake headers-high flow-catback, with no such EM and my car is fine

plus i wouldnt talk to dealers about mods because rather do em myself then trust them since warranty would still be voided if you get water sucked into the motor

CliffNotes: If you do put one in make sure you can tune your engine (i.e. engine management) or you'll be in for a very not-good surprise

EM for CAI? :confused: Sounds Odd.

What EM needed?
What the suprise?

That falls under the "one or two exeptions clause" :p

I also deal with my dealership for modifications and stuff, but usually I just go in and buy parts or have something installed, or just talk for fun, probably cause I know the maintenace people really well (one is a club member) and ive known a person in the parts department for awhile now too :) And im sure there are a few of us who are like that as well with dealerships, and there are one or two good dealerships around who do deal in aftermarket stuff legitimatly, but going blindly into a dealership asking mod questions isnt too smart...

the cobb cai they sell claimed to be quite good in avoiding water into the engine... and its engine, not motor... those remote control electric wrx are motors, scoobies have engines

I dont see how a cold air intake could hurt an N/A car, other than watter, on the maf on an older one.

http://www.100megsfree4.com/dictionary/car-dicm.htm#MudAndSnow

motor:
[1] An electrically driven power unit (electric motor). This term is often incorrectly (but commonly) applied to an internal combustion engine.

1) i was incorrect. it IS the WRX that needs tuning and someone said it would cause supeer-lean conditions. or was it rich. either way...

2) I know next to NOTHING about cars. I installed my intake in 20 minutes. A CAI i would expect wouldnt be much harder since i assume the only difference is running it thru the fender

The 100megsfree4.com definition sucks, cos it regurgitates itself:
motor:
[1] An electrically driven power unit (electric motor). This term is often incorrectly (but commonly) applied to an internal combustion engine.
[2] Rotating machine that transforms fluid or electric energy into a mechanical motion.
[3] An engine
[4] An automobile.
[5] Attaching a generator to a battery in such a way it revolves like an electric motor.
[6] A starting motor. See starter.
[7] To travel by automobile, as in "Let's motor down the road."
Generators don't revolve, much less rotate. Definition 3 stuffs it right into "engine". This thing is a mess.

Further, if "motor" was actually misused instead of "engine", when it's as accepted as "Department of Motor Vehicles" or "Motor Trend" or any of the aforementioned motor-this, motor-that, then it's commonly accepted, and you either roll with it and let the thread stay on topic, or you look like an arse.

Guy on WRXForum gets all anal when you say "wing" instead of "airfoil" or "theory" instead of "hypothesis". His self-righteous correction of a community and industially accepted term, often when used correctly outside his little world, is some lame shot at looking knowledgeable.

Don't be that guy.

I love these motor vs engine fights in every thread.
I don't know much about cars but I figure:
An engine is a type of a motor. A motor is more general. We use the word engine to describe the motor in our vehicles. Your vibrator has a motor :D. It transforms energy into motion.

I installed my Cobb CAI 2 months ago. Seems to run fine, but there is a loud rattle at 4k RPM with WOT. I used some 3/4" PVC foam weatherstripping to help fill the space where the CAI passes through the fender. It helped some, but not completely. Does anyone else have this problem? Any fixes. I haven't been able to pop the hood open at 70+mph and WOT and see where else the rattle might be coming from.

maybe its rattling on the backside of the outside fender metal?

EDIT: better response - OMG a subaru that RATTLES???? *gasp*

Sorry...i have about 304398458 quintillion rattles, squeaks, rubs and bumps on both the inside and outside of my car. Chasing them is getting droll :(

I Have had my Bomz Racing AKA Ebay intake in for about a year now and the only problem I have had is that when at a complete stop and then flooring it my car bogs and sometiems stalls but I was told to get a High Flow MAF. I have had a few run ins with water since I got the Vis Racing CF Hood and the Air Filter sits right under one of the vents a bit of water does get on the Air Filter but the K and N has been really good at keeping water at bey plus a little sheild from my local Autozone for rainney days takes care of the problem. Plus the intake has been dyno proven to give 10HP and 11 LBS on the GC/GF series search the threads there is dyno sheets and everything all for 55 shipped :banana:

One other thing I did note after having it installed was that right before my car shifts at WOT I hear this rattle from the driver side in the dash :confused:

hey man my cobb cai is actually doing the same thing right now... after i run my car hard and the fans kick on my cai is or was bouncin all over in the fender... it scared the $hit outta me at first.... i just moved the stripping on the end of the intake back up to were it was supposed to be in the fender.. it has been all good since... this sounds tacky but if you put a piece of electric tape on the back side of the piece that stops the rattling inside the finder it may help out... softens the nooise a lil anyway...

Okay, here's the million dollar question: For those of us with an '05 wagon, how is our install? I've read where the Injen CAI for '05s is not for wagons cuz they don't have the room in the fender without the fender bulge. I've also not seen a Cobb CAI for an '05 engine. Any help or info would be greatly appreciated! :confused:

I wouldnt try putting one in unless youre pushing a lot of HP. I've heard guys say its slowed them down actually. If you are going to get one, put in the money and get a nice one thats well designed so that it doesnt create turbulance by the MAF sensor. Unabomer has a FAQ about CAI's...and just about anything else youd like to add to the car. I forget if hes on here or I-club though. It is also a good idea to get an EM system to deal with the higher airflow rates.

Filter's on backwards, imp!. Cheers! :alien:

Seems attaching a cone filter directly to my MAF has produced a substantially higher air flow. That's the reason for doing it, right?

Well, the increased airflow is monitored by the ECU and compensated for by dumping a proportionally-increased amount of fuel. The stock 2.2 just can't handle all the goodies and blows unburned gas out the back.

So now, do I get a fatter exhaust to better handle the increase in air/gas flow? Or do I simply replace the stock airbox and use a K&N drop-in?

Opinions welcome and thankfully received...

VooDoo, the Injen intake RD-1222 does fit the wagon quite well, I have it on my 05 RS wagon.

All this talk about reseting the ecu has me wondering...How do I reset the ecu??? I know it's a beginner question, but will somebody humor me?

reset the ECU. This can be done by killing power the ECU or by simply pulling off the neg. battery terminal and pressing the brake pedal for a couple of seconds.

stole that from here: http://forums.nasioc.com/forums/showpost.php?p=3195353&postcount=1
(ps- I believe the rest of that post is won't do anything for NA cars)

to mention, is this stickied or in a FAQ somewhere?I did a couple of quick searches for ecu reset, and didn't hit any title pages. There's one on scoobymods.com but it's kinda of excessive.

Hot air intakes are dyno proven, but when dynos are run, the hood is open so the itnake can suck cold air. Sooooo, when you are driving down the road w/ the hood closed, the air underhood heats up, making it harder to gulp air (even with the air moving, you still get very high underhood temps!)

Anyone have a Cobb CAI for an 02 RS for sale? Sigh, I want one so bad, but I don't wanna fork out $280 to get one brand new.

And yes, the short air intakes...uh... I found absolutely no increase in performance. especially on hot days. It just sucks down hot air thats floating around the engine bay. I'll never use one again.

For crying out loud! Didn't we just have a thread discrediting the difference between short ram temps and CAI temps regarding when the car is under way? In motion, the difference is negligible at best. First one to find the thread wins a cookie... it's here somewhere.

I thought the original thread (where someone actually measured the fender and engine bay temp) was from Scoobymods.com. The difference, once the car was in motion, was only a few degrees F.

Why are you going to have the dealership install something as easy as a CAI??? Installing one will take to ten minutes with a screw driver. When you have to get it serviced, take the thing off and put your stock intake on. Otherwise, start doing toe touches every morning so when the time comes, you can grab your ankles for support while the dealership sticks it in dry. :devil:

Do what I did, go on ebay. Find the cheapest no name brand CAI for your model you can, buy it. When you get it, throw away the filter it comes with, go to advanced auto and buy a K&N cone filter for $50, stick that on and now you have a K&N CAI for about $90 :devil:

Another thing, when you buy a cobb, injen, AEM etc CAI, You are only paying hundreds of dollars for that little brand name sticker. In fact, AEM CAIs come with K&N filters, so you pay 250.00 for intake. The filter costs $50.00, the same piping design costs about 30.00, so that means the little sticker costs 180.00!!! Do yourself and your wallet a favor, use my method and spend the money on a new exhaust.

Have you ever heard of heat soak??? I wrapped my CAI in exhaust wrap to keep temperature down, and my CAI goes all the way down into the fender and takes advantage of the nice little vents on the side of the bumpers on my 02. :D I will admit however, that before I wrapped it, the CAI was still taking in hot air. :(

Rule #1)

NEVER discuss car modifications with a Dealership!!!

Rule #2)

First adjust the nut behind the wheel.

:D

Serious question: Any science behind this, or is it more NASIOC speculation? The bit I was referring to went full tilt with temperature sensors and everything. Your source air is probably the coolest of the bunch, but by how much, and is your wrap actually helping or hindering the situation?

I was told wrapping the pipe itself makes little to no difference since air travels too fast in the pipe to the throttle body to warm up.

That was my impression as well, but I'm open to seeing anything that is measured instead of assumed.
