So where are the true CAI's for our car?

[Crusty Old Shellback]

We now have two companys that have produced an intake system for our car. While I applaud their efforts, they are not a true Cold Air Intake as advertised.

What they have manufactured is not much more than what one could do with some Specturm tubing and a couple of connectors. One of our members has done this already.

If they say it's a true performance system, then where are the back to back dyno test on the same day, within a few hours, to show the improvements?

What they have basically done is removed the OEM Hiemholtz (sp?) sound canceling system and put on a direct tube and filter. About all that really does is increase the engine intake noise. There is no Cold Air coming in nor is there any air being forced into the intake via a ram air system as stated by Weapons R.

This is not an attack on either company, as weapons R seems to think, but more of an educational exercise for those who do not understand the intake system.

If either company can show imperical test data that proves their system actually increases the HP of the engine, then great. Please share it with us.

Having built several Cold Air intakes and Ram air systems over the years as a hobby, I have learned a few things. It's not rocket sience like some would want you to beleive.

I know that the Genny is hard packed with equipment under the hood and may be very difficult for these companies to spend the R&D money necessary to develop and produce a true CAI and that's fine. Then advertise your system for what it is, a intake system that removes the OEM sound canceling intake system. If you have test data that proves a HP increase, then great, provide that and market it as a performance system.

With either setup it would be pretty simple to run a hose from the front grill to the intake and supply cold air.

Here is the kit weapon r sells and at $60 I'm pretty sure it can be done for cheaper as a DIY with some dryer vent and a velocity stack.

If you routed that up behind the heat shield you would get some cold air benefits I would think.

I just went and took a quick look at my '12 R Spec. and a picture of a 4.6 engine bay.

Seems that from the factory, they coem with a Over The Radiator, ram air Cold Air Intake. Those two vents on top of the radiator feed directly into the air box. There is a secondary inlet feeding the main air filter box as well.

So would a good high flow air filter be better than the tube and filter?
Can the factory OTR be enlarged and used to feed a filter system?
Where does the secondary air feed that comes into the bottom of the air box come from?

Yeah an OTR solution could work. Maybe someone could email Vararam and see if they would be interested in working on a Genesis? I don't know of any other mfgr that makes an OTR.

For those that don't know what I'm talking about here is an OTR system for a Pontiac G8.

Aftermarket CAI systems (IMHO), will produce little (very little) of a hp increase. Everyone on these forums just craves (as do I) for ways to increase - and to individualize - our Gennys (mine is a 2012 4.6l to which I have done a Borla catback). A true "Ram Air" system would be quite expensive and truth be told - there is a very limited market for our cars.
I live in the Peoples Republic of CA and the gov agency here called CARB (CA Air Resources Board) must approve ANY CHANGE like a CAI: it must go thru testing by them (think $$$) and receive an approval number that is listed on their website. If you install any aftermarket part to the intake system that does not have a CARB approval number, then your car will not be able to be passed by Smog Checks. My previous Lincoln LSC with a 4.6 (some say copied by Hyundai) had a K&N cone filter that passed smog many times until last year - but that cone filter had never received a smog approval number from CARB and my car was rejected until the original "plumbing" was put back. Fortunately, I had saved my old intake system and re-installed it and took it back (and - it seemed faster - I must say, although I was able to use a K&N (with an approval number) in the "stock" filter location).
So, be careful making any changes as the gov may be looking - not to mention possible warranty issues.

Yep, good ol CARB hit me as well last time I ent to get my '04 Chevy smogged. Seems I didn't put the CARB sticker on the tube for the new intake and filter so they wouldn't pass it. Luckly, like you, I still had the stock box.

Since our car already has a OTR, I'm just wondering if it could be modified to flow more air. Or does it need to be?

To tell the truth, until someone comes up with a tuner for our cars, it's all really mute. Yea we can throw in more air and a free flow exhaust, but to take full advantage of it requires a tuner.

Now if you just want the sound, then yea, go for the aftermarket "CAI" and exhaust. But that's really about all your going to get out of it is a bunch of engine noise.

I have done cone air filters on three Genesis. I used the largest I could fit, which was a K&N #1040. I used the stock oem intake tubing, and retained as much of the oem intake cool air as possible.
I never did any dyno testing, but every dyno test I have seen has had the hood up for additional cooling. Having the hood up negates comparisons as now a cone filter is fully exposed. Nevertheless, I "felt" power gains, but you know how accurate "seat-of pants" dynos are....
I concluded that intake air temperature was more important than airflow resistance at normal driving modes (except WOT). Made some measurements comparing OEM to my open cone filter; and could never quite match/better the temperature differential of the OEM.
So now on my '13 V6 (my first V6) I am using the OEM set up with a bit of aluminum-faced insulation zip-tied around the tract, and a K&N replacement filter.
I did look into an over-the radiator intake ala Corvette. Not possible without a lot of engineering. You'd have to lower the radiator and then split the intake system to accomodate the hood latch.
Also looked into direct pathways from grill to airbox. There is simply no room.
Hyundai has done all it can be done already.
The Weapon R intake tubing kit mentioned above may offer something. I'd propose drilling a 3" diameter hole in the bottom of the oem airbox through the metal beneath the airbox. This would gain access to the space occupied by the backs of the fog lights. It is "dead air" in this space, but it is separated from the engine compartment and undoubtedly cooler air. This would be virtually non-detectible.

Crusty, I wish you could take your experience of making actual CAI and make the OTR Ram Air one fit.

If I only had the time, I would.

Between work, building custom Harleys, racing down in Baja, my Woodworking and playing with trains, I'm a bit busy.

Maybe one day I'll take some time and take a look at it. Right now the Genney is more of a fun family car for me.
