So the Cp-E 3" CAI has no advantage over the MS CAI, since it still has the bottle neck of 2.75" where the sensor is. so it would seem smarter to get the MS CAI, since u can have it and still have ur warranty.
Has no advantage? First of all, I think people are getting confused over the meaning of the "green warranty." Here is an exact quote directly from Mazda:
"MAZDASPEED "Green" Performance Accessories must be specifically approved by Mazda for their particular application.
These parts are warranted for the first 12-months/12,000 miles from the date of purchase, excluding labor."

In no way does it indicate that Mazda has to honor your warranty if your product has a green warranty. It says the product needs to be approved by Mazda. So you need to check with your dealer if they will honor the warranty or NOT. It also says the MS CAI has a 12,000mile/12month warranty,
whereas our CAI carries a lifetime warranty.
And regarding the MAF housing. We're all engineers here, and we've all been trained in fluid dynamics. We know that there is a restriction created when you change pipe diameters, but what Mazda did was take a shortcut when they made their pipe. We went through the extra effort of appropriately sizing the MAF housing so that the fuel trims almost exactly matched the stock fuel trims. If you don't do this, like Mazda didn't, then you may inadvertantly change the air/fuel mixture at closed-loop cruise.
Mazda (or whoever designed their intake, more on this later) took the easy way out by using a pipe that is *close* to (but not the same) the diameter of the stock MAF housing. That way, they don't need to machine a dedicated MAF housing, and can save money by keeping the entire pipe one diameter. So that decision wasn't based on flow restriction, it was based on *cost savings.* The people who think this was done for more performance are living in a dream world (sorry). We, on the other hand, know exactly how we altered the fuel trims, and we made sure that they were consistent before we shipped the product. Did Mazda do this? Your guess is as good as mine, but we have the data to prove it.
We also went through the extra effort of machining an airflow straightener out of billet aluminum, to match our billet MAF housings. If you look in your cp-e intake MAF housing, you'll see one. Why did we go through the extra effort to make these? Because if you look at your stock airbox, you'll see the same style airflow straightener. This is to ensure that the MAF samples the air consistently. Without it, the MAF won't measure the incoming air correctly and may result in erratic performance. This is why we call our CAI the "XCel," because we can guarantee no CEL thanks to our properly engineered MAF housing. We spin them on a CNC lathe and machine them to a diameter with a tolerance of about +/- 0.005", or about three times the diameter of a human hair.
Plus, Mazda has not, and will not post a dyno graph for their intake. So their intake could theoretically make 100hp, or -100hp. So until they actually dyno their product to prove it's effectiveness, like we have, how can you compare the performance between our CAI and theirs? You KNOW how much our CAI makes, but if we said our intake made 20hp with no dyno charts, would you believe us?
And this whole misconception that Mazda designed the CAI just isn't true. Just because it says "Mazdaspeed" on it doesn't mean they made it. If you look at the SPEED6 Mazdaspeed CAI, you'll notice it is IDENTICAL to the AEM CAI. Mazdaspeed bought the design from AEM and put their name on it. I'm not sure who made this particular SPEED3 pipe for them however.
Everything isn't always as it meets the eye. I know everybody on this board isn't familiar with cp-e, as we're new in the SPEED3 community. But what you'll learn, and quickly, is that not only do we engineer our products, instead of just throwing parts together and hoping they work, but we're also straight shooters. We share data with our customers, we love teaching people about the ins-and-outs of the turbocharged MZR, and offer the highest quality parts on the market. I think this will become clearer to people in time.
If you guys every have questions about why we made something the way we did, instead of assuming just ask the makers! I'm almost always on the boards and am happy to answer any questions you guys have. When we say we make the best parts in the business, we're not kidding, and we'll be happy to explain exatly why if you ask us
