Im considering the sealed version, but i cant for the life of me see a benefit over stock+drop-in, really. And the "elite" version is just retarded. I might as well get the Gruppe-M.

Heat soak is only an issue for the first 1-2 sec off the line, so most likely ill end up with an Injen for sound + aesthetics, and upgrade my fmic later.

As another member said, if you really wanna hear the turbo spool go DCI and go DownPipe. These two things will be automatic sex when you drive.

Oh, and don't forget the tune!
The higher the boost the better the orgasmic sound lol
You can run the microfilter without the cowl. I've been doing it for over a year with no problems. Sounds way better and I'm sure there is a slight heat difference.

Haha I've got the standard aFe intake (the "pro" DCI intake), was able to buy it used for $200. I couldn't justify spending opver $500 on a "sealed" intake that's not actually sealed:

In addition, from what I've read it's much more important to get max airflow from your intake (cold air is a plus) and upgrade your FMIC to significantly reduce your IATs. I don't track or drag my car, but since I decided to go FBO and this is my DD, I decided to upgrade everything (from intake, to DPs to my CP + DVs) to make sure once I start running higher boost that I don't break down on the side of the road.

I know w/ the Injen intake, some people have had fitment issues when they upgrade their CP/DVs/BOVs , especially when people run meth. Just something to be conscious of.

If you don't want to go the Dinan route, get the Stett or similar product as it is a true CAI. I've been running the Stett for over a year now and it does everything you want it to.

The majority of intakes in the engine bay with open filters will perform similarly. So its highly based on looks.

Obviously you want cold air and more air flow so an intake that does that would be the optimum choice, however, on a turbo platform the efficiency of your intercooler plays a role in your intake air temperatures too so upgrading that would behoove you a lot more in my opinion.

The N54 aFe Stage 2 SI does product benefits over the stock+drop in. I know cause I tested it and posted the results:



What makes it even more interesting is that the test was done in more harsh weather condition than with the stock+K&N drop in filter..

The Elite version of the intake is to remove that last stock limitation and that is the stock snorkel

After my review of the stand alone and Elite version of the aFe Stage 2, aFePower did notify me that they will be releasing a gaskit kit for this current SI model intake.

Further more they are coming out with a new version that will be exclusively designed for high PSI use. It will also be completely sealed with no nead of gaskits and it will be bigger.

Stett and Dinan are not the ONLY true CAI products out there.

The main objective imho for intake, get air in faster and easier. IAT is a far second to this first objective. Let the fmic do the cooling job.

I agree, I was the one who made it known it was not "truely sealed" which is correctly an enclosure. I was just as disapointed as you were, but worked around it. The facts stands it produces BETTER performance than stock+drop in filter does.

Yes FMIC is more important at this time for you.....
