I own both a 2008 Mazdaspeed3 with mazdaspeed CAI installed by my Mazda dealer and a 2008 RX8 40th anniversary edition with Mazdaspeed CAI installed by my Mazda dealer.
I have NOT had a single problem with either car or either Mazdaspeed CAI. What I have had is greater performance, better fuel economy and lots more smiles and fireworks every time I push the accelerator pedal. I use both cars in all kinds of weather, including rain, cold and snow. And both cars go through the automatic car wash with no problems.
As a longtime Mazda and rotary engine car owner and former Mazda racer, I speak from decades of experience here. Remember the same people who designed the parts that helped me race and likewise helped the RX8s win the 2010 Rolex GT championship, and the same people who built many of the parts for all the winning Mazdas including the 1990 Le Mans winning rotary 787 are the same people who designed and tested the Mazdaspeed CAI .
Until you have run one yourself and can speak from first hand knowledge, don't diss the CAI, whether from Mazda or AEM (which is a great builder). It is the safest and cheapest way to boost the performance of these cars. I know fellow RX8 club members with turbos and more and it is a constant battle to keep from breaking their engines, and many have, costing them lots of money. With the high compression of the renesis engine, it is only safe to run low turbo or supercharger boost, even with electronic engine management gear.
The CAI doesn't radically change the compression characteristics, it just makes the engine breath better with colder denser air for greater and more efficient combustion and horsepower production. It is safe for your engine and easy on your wallet.
Hey if you can get your dealer to agree,in writing, to cover your engine's warranty with an AEM CAI attached, great. I just know this, YOU ARE COVERED WITH THE MAZDASPEED UNIT, PERIOD.
Modifying your rides is fun, I have done it for decades. Just be smart about it, unless you have deep pockets.

Show me proof of this performance boost you speak of, for a CAI on an RX8
What like 5 hp and 1 torque for a couple hundred dollars .... hardly what I call a boost
They're just noise generators ... which is cool ... I love the sound, sound is good.
But nooooOOOooo butt dyno in the world is sensitive enough to pick up any gains in power from a CAI on an 8 .... just not going to happen

I dropped my Rx8 zero to sixty time by .3 sec and upped my top speed from 145 to 150 under cool conditions. Most car mags have found anywhere from 8-12 hp increase with the mazdaspeed CAI. With torque up about 5%
Hey you don't have to believe it, who cares if you don't believe it or want one.
Drive one and then talk negative about it OK. I have raced RX7s in SCCA since my first one in the late seventies, both normally aspirated , and turbo-charged (Racing Beat hand-built racing rotary engine with large single turbo in FIRST GEN RX7 ; Mazda single turbo in SECOND GEN Turbo II, and Mazda twinturbo in THIRD GEN RX7).
I don't have to make up figures, I have driven the cars and had the times. I know the cars and what works. What do you really know, or is it what you have heard ?
BIG DIFFERENCE

As for the MS intake giving 8-12 hp increase, that's a tough one. that MIGHT be a peak number at the flywheel but definitely not translated to whp.
Trust me, I've put over 120+ RX-8's on dyno's over the years and have yet to see anyone make a significant increase with an MS.
I even dyno'd my car with the racing beat and then swapped to the AEM (which is the same as the MS) and HP were within 2 hp which is well within the margin of error for a dyno.

My times are real, if you can't duplicate this there must be another variable. I don't dyno so much as do real world times on the road and the track.
I stand by my results.

I will not have an endless debate with you about having a car set up the same way for testing, I know how to do that. And I will not debate you on my abilities to launch and drive through the gears the same way over and over. I have posted thousands of consistent laps in over thirty years of rotary driving on the street and at tracks like Lime Rock, and the old Bridgehampton, and Mid Ohio, and Road Atlanta, and Road America, and Sears Point and others.
The car is faster after the CAI, and that is the last I will post about this. Believe it or don't.

I am not debating you, not is this an endless debate. I am merely attempting to engage in a productive discussion regarding the variables possible when discussing times or hp figures.
If you are not open to such topics then that is fine with me.
Besides, ignorance is such bliss.

I have the aem cai and live in north jersey so basically the same weather as canada would get. if you honestly have the time do both. Buy the cai for spring summer and fall. And build your own for the winter. Yes I have gone threw car washes and I had to drive threw the feezing rain today.. I've never been more scared in my life. And I like to drift when it rains or go snow drifting. Twice I've had the check engine light pop up while drifting in the rain and snow. It goes away after like 30 seconds. I mean I guess that's when the water evaporates or somthing but having a cai in the winter is scary. It probily rocks in the summer but I want to switch. I'd rather not have to worry about flooding my engine and enjoy the corners as much as you can while they are wet(:

Not sure if u decided on a CAI yet, but on your concern about sucking in water: what about adding a water bypass valve? I know AEM makes them for other applications, i'm sure you could adapt that into the system for the 8.

Good decision to get the CAI. I have them on both my cars, my 2008 40th Anniversary Edition RX8, and my 2008 Mazdaspeed3. The performance difference is real and I have had no problems with either car or CAI unit.

Stupid question, feel free to hit me lol. But I know the aem and mazdaspeed are pretty much the same. But my question is do they make the same sound and are as loud ? Do they also give roughly the same amount of performance (I know there's not much)?
Flame me my flame suit is on lol

Cai
The reason to buy the MS CAI over the AES is because you will have a Mazda warranty on the CAI and the attached engine with the MS kit. You are not covered by Mazda for an AES CAI. You might find a dealer who agrees to cover it for you, but Mazda is not obligated to cover non Mazdaspeed products.
The peace of mind should anything go south with your CAI or engine is worth the extra price. I have MS CAI on both my 2008 40th anniversary RX8 and my 2008 Mazdaspeed3 GT and I sleep better knowing they are covered and my engine warranties are still in play.
Use your head here, or you could be paying for an engine repair yourself latter.

What I drive
Yes I am a Mazda driver since the seventies.
I have owned eight of them, including six rotary cars, a RX3, RX4, all three generations of RX7s and now BOTH a 2008 Mazdaspeed3 GT and a 2008 40th Anniversary Edition RX8.
I used to race the RX7s in SCCA back in the early eighties.
