Aem air straightener for Mazdaspeed CAI

[ericrapp]

Just wondered if anyone has installed this fixit for the Mazdaspeed 3. I purchased mine from JSC for so inexpensive that what the heck! I have my opinion anyone else?

Yeah I have had mine on since October. Have had no problems. Before I used to get more of a stutter at highway speeds when you roll onto the throttle but now its pretty much smoothed everything out. (yes it wasn't below 3000rpms). Its well worth the 15 bucks.

I installed mine a few weeks ago... I thought I noticed a difference at first, but now I don't think it's much different than it was (it wasn't bad to begin with). I haven't logged it before and after though... so I'm sure the MAF readings are cleaner. My butt datalogger just can't pick up the difference.

I was having a random misfire last fall that threw the code. I thought it was an ignition problem, and may still be. I still need to swap out the plugs to the colder Densos but she seems smoother all the way up the rpm band now. I also am using the infamous Butt data logger for now!

How did you guys install it-
With the AFS vanes parallel to the MAF(per the AEM instructions)? or
With the AFS vanes at a 45 degree angle to the MAF(per the MS instructions)?

I installed it parallel to the MAF and haven't had a problem with it.

 

[ericrapp]

oh boy, i did not know about 45 degrees. i installed with splitters being vertical.

Thank you!

air straightener to old style ms cai?

Can I add the straightener to my old style ms cai? I see they are only like $15.

 

[Rotus8]

Should work, no problem.

 

[MS3Steve]

I got my MS CAI in spring of 08 so I believe it is the "old style". I put the straightner in fine and even though I dont have a dashhawk according to what I've read on here it should be helping out.

 

[SomnoSpeed3]

Cool. Was it hard to do? I am sort of a mechanical idiot but hope to change that. I gotta start somewhere.

 

[Bonafide_Spd3]

I too looked at this, all it does is control the air going through the cai? What is the positives of that? I don't know much about this piece. I got my ms cai in fall of 07. It should work

 

[ericrapp]

It is very easy, be sure to line up the vanes though. The purpose of this piece is to decrease the turbulence or swirling at th MAF. I did not think it would do much. But it sure did wonders

hks air straightner?

does anyone knows if the straighner fits the hks reloaded intake.
thanks in advance.

 

[DaleNixon]

^ No need. My LTFTs and STFTs are perfect with the HKS SRI.

 

[Bonafide_Spd3]

What do you mean it did wonders? My cai runs great. Don't see how it would make it run better than it is now

 

[ericrapp]

I did not think i had issues. Now the motor seems to rev much smoother and from 4500 up. it just pulls till redline. Fifth and sixth seem to be affected the most though. I have hit the redline in fifth without realizing that i could be there already. That never used to happen. And sixth just gets silly. Now i have had a bunch of things going on with my car and modifications. Problems and lotsof good things too. I also was having random misfire codes that Mazda was looking at last fall before i put the car up for winter. Maybe it is a combo of the Densos ( colder ) and the air straightener or something else? But my motor is running great right now and the car is strong like bear. i am just an opinion. i have no data to represent. I have checked afrs after bolting on bits worried i might be lean (HAHa hardly)but do not data log. And my project is far from complete also. Folks said there was a problem with the MSCAI so for fifteen bucks what the heck. When you see the piece you will see why it might make sense in some applications.

Hks

I would not think you would need one with the HKS. It is a fix for the AEM Mazdaspeed Cold Air

Redline in 5th? Jesus! How fast is that anyway?
