Picked up the Mazdaspeed CAI for the MS3 today. Trying to make time for before and after dyno runs next week.
At least you could take pictures of the thing so we can see what the kit looks like.(pics)
And how about a scan of the instructions?

Lets try this.



Includes the filter cleaner as well. Got it from Ron Tonkin who had a GB at $310.

Yeah i meant UPS. Theyre just 2 minutes closer than fed ex. Now my intake is sitting about 8 minutes away from my house, totally inaccessable. But anyways its not your fault that they dont deliver on saturdays. BTW thanks very much fo rthe quick turnaround and awesome service. Definitely top notch.
 
anyone have it installed yet? sound? performance? comparison to cpe?

also, how long will the group buy price last for?

javanc, any way i could see it since im in cupertino now?
 
I would say no. Why pay $400 for 4-6 more HP? Doesn't that sound silly to you? You could pay about $1600 for the CAI and the CAT back. That would give you about 30-33 more HP. (Depending on what you read.) That might be worth it, but certainlty the CAI, alone, is not.

Anyone that payed $400 US for a CAi kit for a Speed3 did not look around CP-E and Mazdaspeed units are $300 + or -
Read some of the replies a little closer or perhaps I'm confused about your post.

What I am getting at is that paying $300 for CAI (Again, without installation charges...and if you want Mazda to honor your warranty, they have to do it.)that gives you 4-6 more HP is not worth the money.

Stop right there... How do you know the Mazdaspeed CAI for the MS3 only gains 4-6hp?!? No one, to our knowledge, has yet to dyno the Mazdaspeed CAI. The CP-E CAI has been dynoed at around 15-20hp over stock, and while I don't expect the same for the Mazdaspeed piece, it would most likely not be only 4-6hp.

And what makes you think your warranty is voided if you install the Mazdaspeed CAI yourself? I'd like to hear that explanation.

On further research, I stand corrected on the CAI. I was looking at a CAT-back system as well. I posted another question about the CPE CAI and turbo back combo that maybe someone can answer.

On the warranty issue, I am afraid you are mistaken on that one. Unless you are certified by Mazda definitions (which there are many ways that could be accomplished --- are you a licenced mechanic?), modification of the vehicle can void the warranty to any parts affected by said modifications. Per the Magnuson-Moss Warranty Act, parts of the car that are NOT affected by the modification are still under warranty and the dealer must prove your modifications caused the problem.

Example: You decide (and I am assuming you are not a licenced Mazda mechanic) to install the CAI yourself. You end up blowing your turbo. Mazda says you didn't do the install properly because you were not qualified to do it in the first place and that is why the turbo blew. You say you did it right, but yet you are not more qualified (officially) then anyone off the street. You could fight it in court if you like, but you would more than likely loose. The Mazda dealer has a lot of discretion in determining the cause of a problem and the more direct interaction there is between your mod and the problem, the worse it gets for you.

Second case: You install the CAI yourself, and 2 days later your radio stops working. You are still covered. While parts of the drive train, exhaust, etc., may not be covered anymore, the CAI has nothing to with the radio and no dealer would ever try to argue that with you.

I have been here before. I dealt with this for years with Infiniti and Toyota. I know the law on this one well. Read this...

No doubt you are correct, but what about installing a CAI could possibly harm your turbo unless there actually is something done incorrectly? For sure, putting a nut or bolt or band clamp through the impeller will hurt the turbo, but c'mon.....that isn't Mazda's fault.

Have you seen the AFRs this car runs? It's begging for a CAI and a downpipe at least, if not a turbo back.....it runs so rich that folks are speculating that the factory ecu was programmed with these modifications in mind.

Granted, that doesn't help a warranty issue. Dunno. But when the mags are reporting 30 additional hp from the Mazdaspeed CAI and 3"cat back, and at least one tuner has shown that completely removing the OEM cat back doesn't do much for engine output, well.......the CAI seems pretty sweet to me.

Oh and dcomiskey.....I know you from the vortex, I think. Gotta say, this is a whole 'nutter world. IMHO, Whoosh is not "rice", just real turbo engine doing what it does. It's pure. Turbocharged is not the propriety of Japan. Plenty of deadly serious BMWs, Porsches and Benz whoosh. Few "tweetle" and "honk" however.

Fart cannons are quintessential rice. Tweetling and honking BOVs are rice. Big ass wings are rice. Poor tuning of superb engines is.......unfortunately....Japanese. Can't hold a candle to Bosch here. 9.7:1 AFR on a DISI engine? I rest my case.

This car was meant to have a CAI. Ain't no doubt about it. Make it so. ssssssSSSSSSSSSSSSS.......Whoosh........

Not trying to beat a dead horse here...but I just talked to Mazda again and they stated very solidly that the Mazdaspeed 3 CAI and CAT back exhaust combination adds 35 HP and 30 ft-lbs of torque. They have done the dyno and confirmed the numbers. They did not dyno the CAI alone, but clearly, I don't think it would add 25 HP by itself. (As I have read elsewhere.) In any event, at least we have some data now from Mazda that gives us some solid numbers. I even found this on a drivingsports.com:

"They brought one custom MAZDASPEED3 to the track, outfitted with the same goods you can buy today for your street car. Cold air intake, cat-back exhaust, coilover suspension, and lightweight aluminum wheels with 245/45 tires. On the dyno, MAZDASPEED’s factory-certified full-warranty accessories gave this car another 35 horsepower and 30 foot-pounds of torque. And they let us drive it. "

Oh yeah...they wanted $1400 for the all the parts and $450 for installation...

Keep looking around. Dyno plots will be showing up for just the MS CAI shortly. I picked one up from Ron Tonkin, a vendor here, for under $300 a week ago. Another Mazda 3 forum GB sold maybe 50 units. My daughter was sick the first few days this week so I have not had time to get before and after dyno runs yet.
The dyno runs will be up shortly.

Hello all,

I just purchased my MS3 less than a week ago and I love it. I think it is rare to find a car that is so practical / functional, has a good amount of power, and is reasonably priced. I don't care what the magazines say about the WRX (AWD beating our car), they just don't look as good. I've owned a supercharged G35 coupe (the dyno charts were amazing) and it cost me 2.5 times what I paid for this car and it is almost as fun to drive. That said, I simply love this car. (Except for the stereo -- the lack of an mp3 player option just is beyond me.)

Anyway, the reason I am here, is that I want to know if anyone has any official numbers for the Mazda CAI. My dealer offered to put it on for $290 plus labor. (He said it takes a little less than an hour to do the job - so about $420 all together) However, my concerns are two fold:

1) Is it worth the $400+ dollars? If the HP / torque gain is <10% will I even notice it?

2) If the gain is more than 10%, with the problems with wheel hop, launching, and torque steer at the current power level, why bother in the first place?

What do you think folks?

Here are my initial test results with the MazdaSpeed CAI:

I ran 3 runs in 3rd gear WITH the CAI. Here are my results (Mean values of 3 runs each):

Stock
3rd Gear: 224.0 HP @ 5300 RPM, 238.8 ft-lbs @ 4233 RPM

With MS CAI
3rd Gear: 247.5 HP @ 5200 RPM, 273.0 ft-lbs @ 4267 RPM

The gains

HP: 10%
Torque: 14.3%

Based on Mazda's baseline figures of 263 HP @ 280 ft-lbs Torque, the new numbers should reflect my measured gains and would be 290.5 HP @ 320.1 ft-lbs of Torque!!! That is a gain of 27.5 HP and 20.1 ft-lbs of Torque!

I will do more tests when it dries out here and try doing it in all gears. BTW, I only took measurements without wheel spin. In some cases, I had to feather the throttle to prevent it.

Torque Steer? This car is solid! Even when it slips, it feels good to get a little feedback into your hands. On dry pavement, it can slip a little in 1st or 2nd gear, but you get used to it and it is VERY controllable.
