Has anybody else had this issue with the AAM's? Im just about to get mine tuned, Im currently running them with the restricters in.

I would like to point out that technically it is not an issue of the intakes themselves. A cold air intake is just a pipe with a filter at the end, the issue I had is that my tuner, for some reason, could not adjust properly the MAF scaling.
Also, in my post I'm referring to the intakes in R-Line mode, in S-Line I bet you won't have any problem. Don't get me wrong, they are definitely very good intakes but after having tried the G3s too my personal preference goes toward the Stillens. Unfortunately I don't have a dyno comparison with the AAMs in S-Line and that's what I would like to see to see, I can just speak about butt-feelings haha.

Unless of course you have the AEM CAI, which has a computer chip (which fails) to trick the MAF sensors.

I have had my AEM intakes installed on my 2013 for a few thousand miles now and have had no issues. Im aware that the boxes sometimes have issues, but I am fortunate enough to not have them yet.

I am planning on getting a tune and using that wiring as a jumper and then tuning the maf with maf scaling by someone who knows what theyre doing.

No need to spread misinformation however.

@cdoxp800: afaik with 2.75'' intakes MAF scaling is apparently necessary.

Humm. I have the Akuma intakes " 2.75" pipe and all we did was change the fuel multiplier.
Seems the tuner did it the really HARD way.

Have you dyno'd? You won't know a drop of power unless you do. A guy from Indy drove here, never had a complaint. Had it tuned for months. Did a dyno day and had less HP than stock. Sell that junk and get a real cai! Tricking the ecu is like a gt wing on a corola. Its pointless and ghetto.

coolvans1988 · 12-12-2013, 06:50 PM

Did you do your tune at Specialty Z?

I ordered my set of the AAM CAI, since theres some issues based on your review with the uprev tune when doing the R-Line mode. You think its possible to still do the tune while in S-Line mode?

Leuz · 12-12-2013, 08:48 PM

CAIs in S-Line mode should not have any problem. I used them in S-Line on my stock Z without a tune with no problem at all.
Technically you should not having issues in R-Line mode either with a proper tune. I "think" we were not tuning the MAF scaling correctly but, at the same time, I also don't know of anybody that has successfully tuned them in R-Line. I'd love to hear from them tho

My AEM's paired with pulley's untuned and broken O2 sensors gained 16whp on top of the full exhaust. Had things been running perfectly and with tuning, I don't doubt the gains would have been 25 or more. Unfortunately I didn't know about the O2 issue until after FI so no info on after it was fixed NA.

If stillen makes a 2.34" ID pipe the whole way from behind the filter to the TB, then so should everyone else since that's the ID of OEM too.

I am planning on getting a tune. I've had a few people recommend to me going with a CAI with a larger diameter such as the AAM 2.75" and the Admin Tuning 3" for more flow, but considering what you are saying perhaps it would be best to go with Stillen, Z1, or the like if theres no plans to enlarge the ID elsewhere. Does anyone else agree with Synolimit?

Any updates on this anyone ? Anyone find success with this intake ?

You running stock throttle bodies? If so, why run a larger pipe. You'll just have a bottle neck at the bodies. People have run larger pipe and said them have picked some power. But I haven't seen a dyno chart to prove it.

It looks like I am going with Synolimit's kit with ported TB at 63mm to go along with my FI TDX 18" + FI RHFC. So for intake I will decide over AAM or z1. Leaning to AAM unless I can find a reason not too. I am assuming the AAM 2.75" intake over the 2.5" Z1 should benefit but I would rather not assume. But perhaps keeping everything more consistent around 2.5" would be best. I don't know. Maybe makes no difference. Presently searching for an answer.

If you can. Do a before and after dyno runs.
