Airaid Track Day Filter pre-installed

[kanniiee]

So I purchased my 15 GT in December with about 16,000 miles on it. The previous owner installed the Airaid CAI linked below. I noticed that the car "flutters" under acceleration fairly often. When I had the catted longtubes and custom tune done a few weeks ago the tuner mentioned that I have some odd bursts of Air across the sensor when he was dialing it in but he tried to tune some of it out. I can still feel it now but I am trying to figure out if the issue would be this "track only" CAI with the aggressive filter and no box?

Any input would be helpful. Contemplating swapping the CAI for a different design just to see.

That said, she put down a lot of power. More than the tuner expected for an A8 with just full exhaust and a CAI. 412/381

The "track use only" crap is just marketing BS. That intake is fundamentally no different than any other open box except clearly it has a airflow "smoothness" problem.

Personally, I would migrate to a Steeda CAI (proven results), GT350 CAI (from Ford; I use and prefer this; flows almost as much as the ugly PMAS), or an Injen if you want an enclosed box that looks damn near stock (except for INJEN being molded on it).

I would go back to a factory box and appropriate tune FIRST to ensure there are no issues that are unrelated to the intake.

The regular air raid sealed box or livernois windstorm version is a great intake. When cruising my IAT are usually 3-4 Celsius above ambient. Even sitting in traffic they don't get extremely high lIke some of the Temps I've been seeing around here with open box setups. Once you let er Rip again they fall right back down pretty quickly.

I also notice on the page it says that it's no tune required. Meaning it has the reducer insert in front of the MAF. Maybe this is also affecting things with the tune. Just tossing some ideas around.

I looked for a reducer insert but I don't see anything. I guess I will pull the trigger on a new tune required CAI and have them adjust the tune after I install.

There are so many options to choose from. Choosing between:

Steeda ProFlow Cold Air Intake - Tune Required
JLT Cold Air Intake - Tune Rquired
Airaid Cold Air Intake - SynthaMax Dry Filter with sealed box
PMAS Cold Air Intake System Velocity With Tune Required

Does it really make much of a difference? I will be getting the tune revised at no cost so that is not an issue.

Any open box intake will run higher IAT Temps than closed box 100% of the time. Yes it does.

The reducer insert on the s550 can't be removed by just removing it per se. It's moulded into the intake tube right in front of the MAF. You can remove it with a dremel tool.

You'll know if its in there. Stick your arm through. If it fits it's not in there (unless your skeletor), if it doesn't fit it's in there (unless your hulk hogan)

I've noticed a lot of the kits have a "no-tune" insert which is what I was looking for on mine. Basically, this just sounds like a bottleneck to me.

I see what you are saying now.

It looks like the intake tube is the same on your box kit as mine but I don't know if its possible to just order the synthamax filter and box only?

It is not a bottleneck, the stock MAF diameter is bigger then the TB.

I'd go Steeda, airaid, or PMAS. I have an airaid and dyno'd just as high (and higher than some) as steeda and PMAS equipped cars at two local dyno days. I really don't think it makes that much of a difference.

A tune without that vs with that MVT insert will always make more power without.

So call it what you will, bottleneck, restriction, modular venturi tube. Remove it and get tuned and you'll see more power.

Quoting John N @ Lund Racing, from just yesterday:

...Its not going to make much of a difference for the cut out insert.

Really the whole point of my post was to gather any experience or ideas about why the air could be surging and fluctuating so bad with this current setup. I am probably going to order a new PMAS intake and install myself. Then I will have my tuner run it again. I just don't know what the previous owner did. My tuner has been doing this a long time and said he hasn't seen fluctuations like that before.
