Kinda' what I had thought after researching. Prior to research, I had high hopes of 15HP gain....... NOT !!!!

It is a common belief that an CAI will free up power gains, which clearly is not the case. Coming from a 2010 STI I learned that any power mod will require a proper tune / ECU re-flash.
In order to get the most gains from a CAI, you must re-scale your Mass Air Flow sensor. Your MAF sensor directly controls your fueling in open loop, so a CAI will make your car run very lean therefore you car will not produce sufficient power. If a CEL (check engine light) is triggered which very well possibly can happen, the car will inadvertently run in limp mode which just dumps fuel and will run extremely shitty. My best advise is not to mess with it until a proper module is built to piggyback on the ECU (very much like the COBB ACCESS PORT) or open source tuning capabilities with a laptop computer.
Hopefully someone down the line will be able to break the code.
I will be standing by until then...

A few points.

- Running leaner is one of the factors in tuning that creates more power, whether it's safe or not though....
- Popping a lean/rich/MAF sensor sensor CEL will not throw a car into limp mode, at least not a Subaru \/

CAI may give you a little roar in sound plus a few ponnies gain at best.
I concur with proper tuning and a little time for ECU to adopt.
Speaking from own experience with almost the same 3.8 Lambda engine in my coupe.
Mine gained 15% whp after a painstaking 2 hrs dyno tune and it paid off.
And all I did was adding a CAI and CBE.

Refer to CEL PO171 (System too lean). I got that from trying to lean it out get the most power more that one occasion... Tell me about a problem I haven't had... I had a GRB STI. 2 fully built motor tuned for E85 @ 450hp/420tq (tuned by Phatron from Phatbotti Tuning) I loved that car to death but my wife just had our fifth kid and i was dumping too much money in that thing, it had to go... (Please don't take any offense to what I wrote, it is not my intention, we aint supposed to be ruthless on here like we do on NASIOC/IWSTI LOL!!!)
I find myself wanting more out of 5.0 Equus everyday... Whether it be a CAI, full exhaust header on back, I wish I could tap into an open source program to tune my shift points and advance timing curve.
As you can tell, I still have the tuning/mod bug.

I wouldn't want to go to bed with the CIA.

You'd never wake up. LOL

Engine #8 here (mostly improperly built by 'reputable' shops). The bug never goes away. Part of the reason I got the Genesis as a DD, because there is so little support for it but it still makes enough power to leave me completely disappointed. The long warranty also helped.

The intake test in the video is not particularly a great test because it really depends model to model. The intake becomes a restrictive at different points. Some of the GM LS series motors with intakes actually see decent gains with no other mods, while a WRX/STI will see about the same kind of gains from an intake only with a turboback exhaust and accompanying tuning. It really just depends on the car in question.

That being said, manufacturer quoted gains are, without exception, always going to be completely bogus.

LOL!!! you got that right!


Who on here is located in SOCAL?

A CAI is kind of like shoes. Better ones will help some people, but won;t help everybody. I had a 3000GT VR-4 and I can say for certain that I gained more ponies from adding a K&N CAI. I felt it in the seat as well as on the dyno. It's been a few years so I don't remember the numbers, but it definitely helped. It only cost $80 at the time and it was well worth it.

Like "Brafatal" said, it depends ont eh car. If everything is already maximixed for performance you won;t see an improvement. But I suspect that Genesis sedan airboxes are designed with quietness being prioritized over air flow so I'd guess there is something to be gained with a CAI.
