Ok, got it! Thanks Jason.
SRI - Cobb or K&N?

Ok, got it! Thanks Jason.
WOW...regardless that the K&n made alittle more ponies..both intakes made 25+ hp over stock according to that dyno. Do you have any other mods at all..anything over 15 hp for a sri is pretty high..regardless wow. Back to the intake question..get what you want..there all wayyy better than stock...the corksport is nice piece..PG makes a good product..K&n is nice..little spendy..but dealerships seem to overlook K&N when it comes to warranty prabs..and the Cobb intake is very nice and good priced..and is perfect if you plan to go with more mods and tune your car...Good Luck.
i believe you can buy the AEM plastic straightener by itself... i remember seeing it on that "roadmember" site.

While we are partial to our intake, we must stress that no matter what intake you get, you must support it with proper tuning. Intakes make power because they alter airflow, which alters load readings which alters boost. A properly tuned car will make much more power, more reliably than just an intake. Although, our intakes do rock!

Yes, we recommend tuning for any intake. We have found that on modern, turbocharged cars, intakes require tuning no matter if you have an EVOX, STI or an MS3!
We have no release date at this time. The new ECU is going to take some time to figure out.
Yeah - here's our blog post that talks about the staged gains:
http://www.corksport.com/blog/staged-dyno-results-for-2010-mazdaspeed3/
A quick quote from there to answer your question:
"Stock vs. Power Series Intake System
Our $239 intake system includes our aluminum turbo inlet pipe, billet MAF housing and CorkSport Dry Flow Air Filter. Again, this package includes the turbo inlet pipe -it is the only system on the market that is packaged including the inlet pipe -all others are marketed separately. The torque gains were nearly 20ft lbs increase on average. We also saw large sections of torque gain that were up to 33ft lbs of torque. The horsepower gains were equally impressive with the largest differential being a 36whp gain over the stock numbers. Our system works great, we have put a lot of time into the design and validation testing of it and it generates some serious powerat $6.63 per horse at the wheels."
To echo what Travis at Cobb was saying earlier, the diminishing returns you see in stacking mods on top of each other (the blog post details intake, intake + racepipe, intake + racepipe + downpipe) really speak to the value of a tune. Gains should go up markedly from there with the tuning.

get a tune, you will have very substantial gains if you go to a reputable shop.

Why has no one mentioned CP-e's SRI ?
The Nano is also a pretty good SRI considering it has an aluminum MAF housing, air straightner and a pretty good bracket
I'm thinking probably because it's pricier when purchased new. On the other hand, when they're sold as used, the price is pretty much the same as the Cobb piece used. I got a great deal on a used cp-e SRI and couldn't be happier
I have a corksport sri... actually it came from my cx-7 but it fits the ms3 just fine. I love the quality of it as well as the appearance. i can't say much about performance, because I switched it over the day after I bougt the ms3...however the sound and added hp feels better overall in terms of performance, but much of that could be in my brain...

Had a good friend of mine back when I had my Integra do a full breakdown on CAI's vs. Short rams.
Yes the CAI will usually jump your HP a little more than a comparable short ram on a dyno. But the problem is you aren't moving. There is no airflow into the engine, definately nothing near what it is when you are at speed. Once you are at 15-20 mph, the airflow is constant and a short ram isn't pulling a much higher temp/denser o2 level.
The other thing he mentioned was that since the CAI's are longer, they are just a bit slower at initially pulling in air than a short ram, so even that starting first 50 feet HP gain is questionable.

50 ft. HP gain? Traveling distance at launch I presume. Where does that number come from?
When you hit the throttle WOT at launch the air draw through the intake whether SRI or CAI is very powerful. We're talking about a tiny sub-fraction of a second to move colder than engine bay air outside that extra 3-4 feet to displace the volume of warmer air already present in the tube. We're talking about huge amounts of air being sucked into the engine when you go WOT.
