Aem air straightener for Mazdaspeed CAI

the first time i put it on, i put it parallel with the maf. this time i went with 45* from parallel with the maf

Understood, but would that be putting it straight up and down (45 degrees rotated left from the MAF), or would it be a full 90 degrees from vertical, (45 degrees to the right from the MAF)? You went 45 degrees in which direction? Just curious.

i went 45 degrees counter clockwise of parallel with the sensor. understand though that I think you are over thinking this. There is no horizontal effect or standard on this. If there were the instructions would be to make sure that the car is level, the sun is at its 12 o'clock position, etc....
 
I just got one delivered and it came with a ridiculous sticker I would never put on my car and a foldout with more stuff they want me to buy, but no instructions. Good thing for forums or I wouldn`t have any idea how to orient the thing.
 
Sorry, GoFast. I think I'm confusing you. As you stand in front of the car with the hood up, looking at the intake, you will see that the MAF on the MSCAI sits off to the the right at about a 45 degree angle from vertical. I took the instructions (including the AEM photo) to mean that I was to align the vanes on the straightener parallel with the part of the MAF that extends down into the intake.

So, if you put the straightener in so that its vanes line up paralled with the internal part of the MAF inside the tube, it will be at about a 45 degree angle to the right of vertical. Am I making any sense?

I was just trying to see if you went to the left or to the right of that alignment. If you go left or counterclockwise, then the vanes would be pretty close to vertical as you look at the tube. If you go right or clockwise of being aligned parallel to the MAF, then you end up 90 degrees to the right, if that makes sense. I could draw this out.

It sounds to me that you are saying that you went counterclockwise of being parallel to the MAF. To me that would have the vanes of your straightener lined up pretty much straight up and down. Am I understanding this correctly now.

If this makes a difference it would be good to know how to repeat your alignment.

BTW: I have no intake related CEL's. I do have CEL's from my catless exhaust, which comes with the territory. lol.

Just got my straightener in the mail. No instrucions or paperwork. Boo! I think I can figure it out though thanks to the link with the pics. Anything I should be careful of?
 
the vid

helped me out a ton. stopped my small stutters and fixed my ltft's. yeeeey no more cel or stutters.
nice nice. I was looking at the you tube and recall when we first saw that on the forum! It still looks like driver 311 and Laloosh have the fastest quarter milers according to dragtimes.com. But it looks like someone here is closing in on that. What is your build date 32007? Mine was 2/07 with a delivery in May and dealer installed Cold air.

JSC speed helped me out alot on this and linked me to the aem cold air intake install, which included the picture of the straightener. Maybe Josh could help anyone else who has questions about this piece!
 
Nothing crazy you should be good. I did disconnect my battery for this one though. i took it easy till i had quite a few restarts and some miles on it before i got pushed it very hard. good luck
 
I understand what you are saying, I just didnt understand the relevance

No s***. It's either the vanes are parallel with the MAF or they are angled at a 45* angle to the MAF. This guy is going to confuse the **** out of people trying to sound smart. (deadhorse
 
There are other threads here on this (several). I posted the AEM install on one of them, but will post again here. Since the MSCAI is just a rebranded AEM, just follow the instructions and the pictures.

Installing at 45 degrees to the right of vertical is the same as installing the straightener parallel to the internal shape of the MAF, because the MAF is that many degrees to the right of vertical.

Just forget the degree thing and line up the vanes of the straightener with the internal sides of the MAF, it's all the same thing. Here's the instructions, look at the photo at the bottom right of page 6. That's how you need to line it up.

Does anybody have a link to the Mazda directions or at least a copy of their drawing/photo of the installed piece? Because all this s*** about the rotation has my head rotating like Linda Blair`s.
Bottom line: Does Mazda say to install the thing the same as AEM (parallel to the MAF) and it is just terminology or does Mazda say to have the vanes going across the MAF on a diagonal?

**I ripped this off of another forum**

Just line the vanes of the straightener parallel to the sides of the MAF. It's that simple. Parallel to the MAF is 45 degrees from vertical. All the same thing. Match the AEM photo, tighten it all up and drive the thing. Don't know who made the other photo, probably not AEM or Mazda, just some guy's own idea.

Initially that is the way I had it orientated and still tripped a CEL. If you have the AEM version of the cai, then follow their instructions. If you have the MS version of the intake then follow the mazda instructions. There has to be a reason they did it that way. Since following the mazda instructions, I have had no cel in over 400 miles. Before it took me about 200 miles to re-trip it.
