Thanks. Looking for area tuners in VA/NC now, probably going to go ahead and get a down pipe installed as well.

It's all about Money. A company needs to pay to have an item tested and certified in order for that company to legally say that their item is CARB legal. Yes, it's the same intake, and yes, it's only 2008 CARB certified.

Bummer.

OP, I highly recommend torqued performance. He even has maps specifically for this intake. Look it up on his website, torquedperformance.com

Hope that helps !

So is everyone pretty much in agreement that this is safe for a stock tune but that you don't see much if anything in gains until you get a tune?

Or are there people who have gotten gains with this intake while maitaining a stock tune?

And I realize Subarus are not known for doing well with an intake and without a tune but I don't know if they have changed the past couple years.

You will notice a difference, however it is not safe to use without a tune. Running lean = Bad JuJu

Running lean is definitely not a safe bet.

A shop once left my airbox clasps open for a couple days on the 09 I had after doing a lttle work, I was wondering two things...why am I missing 4 miles per gallon, and why can I hear my bypass valve.

I bet the same thing would happen if anyone added an intake without a tune.

I don't know if the OP had answered or not but have there been any water issues? Here in Nebraska, snow, huge rain puddles, and other muddy things are always lurking around on our streets at different seasons. Heck, even the car washes spray water up under the car now here. I am about to do this mod just don't want to if you have had any problems with water getting up in there.

And did you still have the stock ECU program on it? Was wondering how that has been affecting it too. I cannot get away with a voided warranty. Will be getting rid of the car once it hits 30,000 miles and that will kill the trade in.

Read the rest of the thread. Those questions have all been answered already. Here's the bottom line from what I've personally experienced with the Prodrive CAI on my 2004 WRX:

-ANY cold air intake that is a certain length below the headlights runs the risk of ingesting water if you enter a deep enough puddle or if rain directly contacts the filter. Water finds a way in and if the intake gets submerged, the water will be sucked into the engine. If the MAF sensor senses water, it will kill ignition and you could get stuck in the deep water. Or if the filter gets wet enough and that water hits the MAF sensor, it will kill ignition as you drive causing dangerous engine stuttering and a check engine light. Also, if the filter gets wet enough, your engine might not start for a minute. Basically, if you run through deep puddles or run the risk of doing that during a storm, then get a shorty intake instead or some other intake better protected from water. Or, you can avoid all deep puddles.

-ANY intake you put on your car, regardless of who makes it, will change the way the engine runs. Don't get a tune and you will lose MPG, increase the amount of black soot coming out of your tail pipe, cause coking of internal parts like the plugs, and cause a few other potential problems with the engine. Is that enough to warrant a tune? That's up to you. So with the price of the intake, you should also budget for the price of a tune if you care about taking care of your engine long term.

Hope this helps. Again, this is my own personal experience with the Prodrive CAI, not a reflection on this specific AEM intake.

Truer words have never been spoken!
For the 1,245,899th time - You will not gain much, if any, hp from an untuned intake. Your car will not run very efficiently & you run the risk of damaging your engine if you run any aftermarket intake UNTUNED! I would not feel very safe driving aggressively on the the stock tune (it sucks!). Running the stock tune w/ an aftermarket intake is just plain dumb. Most OTS tunes have specific maps for the AEM - cough up the $75 - $150 bucks & do it right!

Even with a tune after market intakes carry higher overall IAT'S which can quickly hinder performance. My. 02

True for short rams. AEM's CAI sucks air out of the foglight area (sealed off by their baffle plate), so temps should be a few degrees lower than the OEM airbox.

Question CAIs and warranties

Does installing any cold air intake void the manufacturer's warranty? And what does it do to your mileage?

I have a 2011 STI and am considering a CAI. Should I hold off until I am ready to pull the trigger on an upgraded exhaust and retune?

Yes; you're asking for a warranty denial if some dealers find that you're running anything other than stock configuration.
You should wait for a retune. Even a Stage 1 retune will net you much more of a performance boost than an aftermarket intake on the OEM tune.
You couldn't pay me to put an aftermarket intake on a car with the OEM tune - a complete waste of money & you run the risk of damaging your engine.

BTW - Stage 2 is where the fun really begins - definitely do that first.

As I stated before, it's not a good idea without a retune.
I installed a Harman Motive after I went Stage 2. I didn't retune for the intake & it introduced more lag & didn't give me any additional performance, so I sold it. My AEM CAI had the same result until I rescaled my MAF. The retune was necessary to get your AF mixture consistent & correct throughout the airflow/rpm range.
No matter what vendors/manufacturers say, ALL aftermarket intakes require a retune if you want to play it safe with your engine & if you want the additional power. Without a retune, all you've got is a loud sucky noise & a slower car.
(Sheesh! Hasn't there already been about 1.8 million posts confirming this already?!)

^^Look up 5 posts. What he said.
Torqued Performance has the best OTS (Off The Shelf) tunes. I've got a local guy who whips up excellent custom tunes. I prefer OS to AP since OS is much cheaper - $180 for a Tactrix 2.0 cable & about $75 for a map vs. $600+ for an AP.
I also like OS for logging - free software & can use a WB 02 sensor for fine-tuning your fueling - see Romraider.com for free software.

Thanks

Default deep puddles

how deep we talking for deep puddles? i just bought a 2012 wrx hatch, and i really want to get to modding, but everyone keeps saying wait until your warrnty wears off..36 k or 3 years... weigh in anyone?
and then for the water thing. I understand that AEM makes filter mask to prevent dirt and water from entering.. anyone have this option or have any feed back on it?

You'll be fine unless you completely submerge the right front fender well (we're talking about 12" of water). The risk of hydrolocking CAI's has been greatly exaggerated.

Since an intake will net you less than 10 ponies by itself, you'll get more bang for your buck by going with a downpipe & a Stage 2 tune first. One caveat though - once you do mod the car, your local dealer may see fit to refuse certain warranty claims if they think your mods contributed to the problem. IMO, the risk is worth it - I went Stage 2 before my '09 turned 10K miles & have been happy ever since. I haven't had any warranty claims other than a noisy bearing in my tranny that the service tech (and resident Subie tuner) fixed for free. Good luck & have fun with it!

My mate has a factory 2010 Sti hatch and mine absolutely smokes his off the mark and all the way through, so very very happy

For the OP, do what you want, its your car. Congrats on gaining 5 - 15 hp, or if any.
