I've had my MSCAI for over 15,000 miles now on my 2008 with no issues what so ever...
Now, whats this I hear about colder plugs burning more fuel, etc...?
Where can I get more info on this...? Hmmm....(scratch)

colder plugs don't burn more fuel, they are colder for a reason. The higher the number on the plug, the colder the plug.
In my high hp turbo car I run a 7series plug.
Most stock cars, na, run a 5, in a turbo car I would recommend a 6.
I highly doubt you will see any change in fuel economy from changing the heat level on the plug. If it is fouled than thats one thing.
But typically you want a colder plug for high heat turbo cars, so you don't get predet, or even worse just burn one of the plugs right off, then you have those pieces of metal rumblin around with your piston and valves. not good.

+1 colder plugs = less chance of det
You shouldn't be worried about pre-detonation at all as long as you are running 91 octane or better. If my car pre-detonated at 91 or better I would have Mazda running around to make me a happy man. There is NO reason the car should pre-detonate under stock or approved Mazda upgrade conditions.
More boost and or advanced timing, the colder plugs. would then help, IMo. The Mazda tune, she is a funny thing. every one should pull their plugs, do the free mod while in there and see if you are too hot or cold or rich or lean. You young fella's should know, if you can not wide band the o2. it's all you have to see the air fuel burn result. Again, my North East Coast Old guy Sticky tires opinion

uhhh.... (dunno)
If you do not use a wide band sensor as you modify a car, how can you be sure you are not running into a lean condition under load or at all. Some people can tell you from experience that not having not enough fuel or too lean will do bad things to the internals of a motor. My point should have been that if you do not wide band your car, to be sure it is running safely, you should 'read' your spark plugs. That is what us old folks used to do. To check the spark and fuel results of modifications to the engine. And yes rich is safer, but the car is not running to its potential. Sorry for mix up elie

CAIs are absolutely useless on turboed cars.
all it does is mess with your MAF and sends false readings to the ECU.
this is the fact, and is most likely why mazda doesnt want to be behind a part like that......
....now if u run speed density, or MAP then that's another story. unfortunately MS3s dont.
CAI is a waste of money IMHO. get a good drop in filter and it will give you better results without interfering with MAF readings.
and to those who will puke at me with "dyno this, dyno that"
show me 40-50 back to back runs on a dyne, then we'll talk. consistency is what u want in a street car, NOT being able to have a good run once a week.

I wouldn't make statements like this until you first hand know what you are talking about...
Mazda themselves claim a 30HP increase from their CAI and CBE...gains mostly coming from the intake. Cobb, BEGi, CP-E, AEM, Injen, etc all have shown gains...consistent gains... I was one at first was skeptic about intake gain claims for this car...until you first hand experience the difference you won't believe it... Its a known fact that the MS3 stock intake is the MOST restrictive intake out there...
Fact, upgrading your intake on a MS3 will yield you HP; and not some measly 5HP either!!!! Enough horsepower the cause traction issues...
You're about to get piled on... (wedge)
(lol2)
I had my car at the dealer today for the fuel pump TSB, and the service manager looked up the intake recall...said it only applies to the ones made in the last 4-5 months. Apparently the "older" ones don't have the same problem, but I wasn't aware that there's been any revision to it?
He said I can keep it and as long as there's no CEL it's fine. Even if they found it was causing a CEL it would be covered by Mazda.
So I guess I'm in the clear.

Good info, thanks.
Seems if all that is true then I to am in the clear. My CAI is about 1 year old and has never given me a problem.
yep.
There are arguments as to the difference in intakes; SRI, CAI, affecting the temps. But all of these flow more volume than the stock. And Turbos love lots of air and no resistance on the backside. All motor a bit different. And yes cooler air is a good thing in a performance vehicle.
One thing to remember with SRI or CAI is the intercooler. On a 65* day the coldest your intake temps will be is................65*. Doesn't matter what the temp is going into the turbo...no matter if it's 75* because of a CAI or 100* with an SRI......... it will be 65* after the intercooler.
MS CAI on this car is for keeping the warrenty and good looks.
I have both the Cobb SRI and the MS CAI. I run the MS CAI because for some odd reason I get better MPG with it?????

i have bothe and im sticking with the cobb. i havnt had problems with either.
testing has showed that while car is in motion the diffrence in air temps of the cai vs the sri are negligable. i didnt belive it untill i used my dashhawk and noticed no diffrence. when your sitting at a light the sri heats up faster but the cai heats up as well. i just switched over to the cobb sri (cobb AP) and the sound is about the same. i was more at ease when we had a big rain this week driving around then i was with my cai. granted the chances of hydrolock are low with a CAI its still higher then a SRI.
