Which Intake are you getting?!
 

So far I have only seen 3 intakes being offered on the market for the FR-S. Obviously, there is probably more, but from what i've read on the boards the main ones are:

1) Injen
2) Takeda
3) Airaid

Which intake are you getting for your car and why? If it's not on the list, please let me know which one.

Im really partial to injen, but from what i've read the SRIs are losing a little torque, which is what this card needs :( May hold off to see the development.

I'm gonna wait as well. See what AEM and K&N come out with.

Also, I usually wait for the second version for them to work out the bugs. Also, I want to see a CAI, with a good tune.

May want to add a poll, but definitely Injen for me. The fact that they used my car for development aside (full disclosure), I like the look the best and the all the R&D and production is done local to me. The performance is definitely where I had hoped it would be at, and I've been driving on the prototype for 1500 miles, already.

The sound is amazing, too, but I'm sure they all sound better than the stock intake.

AIRAID is a close second, but the Takeda offering looks highly shady to me, especially since they don't post dynos or proof.

Besides, I know someone who used to work there, and I'm not impressed at all. ;)

How about none.. I'm not yet convinced that intakes make any power. I'm thinking the stock intake without the noise pipe and resonator is just fine.

dyno graphs aren't proof or you don't believe the numbers?

I beg to differ.......

I have serious doubts about the veracity of their claims. :)

One of my main concerns is that this is a 3rd gear pull, and the baseline numbers are pulled 3 weeks before the newer intake is installed. All baseline dynos have shown an increase in power just after the standard break-in.

By comparison, the Injen intake pulls are done back to back and 3rd gear shows 12hp at peak.

I ordered the Injen intake today. I hope have it sometime next week.

How do you guys think the injen would compare to the Airaid,

does anybody know if SRT if making an intake

I agree with your assessments and you make valid points. You may even be 100% right.

But don't say they are not providing dynos because they exist.

Can you comment on how Injen's intake feel? (Try to be unbiased). I know most probably close to redline it must pull GOOD. But what about the rest of the revline?

Haven't seen Injens final product yet, but....I need a closer look at the inside of that Takeda box. The AirRaid box is a good design but isn't absolutely optimal for minimalizing turbulence on the way in. While the difference is minor, its still a difference.

I'm waiting for Perrin. I like how it goes up under the bumper instead of in the engine bay like the rest. Also after reading their posts on here and seeing how much they are dedicated to this platform, if anybody is getting my money they will be one of the first.

Doesn't really tell me anything. Is their "Big intake" a Cold air intake?

I'm sure the dyno graphs are close to accurate.. What I don't believe is that the intake itself makes a whole lot of power.

So naturally, you're thinking.. "what an idiot, clearly if he could read he could see that the dyno plots show around 5hp gain on average." Seems pretty simple right..

I disagree. I don't think the intake is really making that much power. What I think is that the power gain is a byproduct of leaning out the a/f ratio at higher rpm's.

I'd rather wait for a good tuning option to adjust a/f ration's to max hp the proper way. I think the stock system is just fine.. though I hate the noise generator and the resonator. I'll cap those and be happy with the stock system until I reach a point when I can see proof that a tuning or turbo and tune require a replacement intake to improve results.

I think this argument is basically "what comes first, the chicken or the egg?"

You are right the HP is made because the a/f is leaning out, but why is it leaning out? Well, because of the intake. That is one of the things a tune will do, lean out the a/f a little bit because stock is too rich. So again, which made the power, the a/f leaning out ok; but what leaned out the a/f ratio?? The intake. So if a=b and b=c, a=c

Anyone feel free to correct me. :happy0180:

Oh, no, you're right, I didn't know they had posted a dyno when I made that last post (until you posted that link). I had just been requesting info from them for a month and had no reply. :)

Honestly, I love the intake. Aside from just how gosh darn cool the guys are down there, this is my first tuner part, ever. Yes, I'm a noob, sorry. :(

That being said, all I can do is compare it to stock. It's a huge difference in sound and throttle response, and the car clearly accelerates quicker (especially at high RPM). Even at low RPM, though, the increased airflow (or something) makes the engine feel much more responsive, which I completely appreciate.

I really hope everyone picks the intake they prefer. I like some of the other offerings a lot, but the reasons I stated above made Injen my favorite, aside from having met all the guys. I love the look of the polished tube coming out of the black airbox. :)

I am torn with all of them. I think I'm just going to wait it out a little longer and get one later on.

Thanks for the feedback. :happy0180:

Since you didn't read the blog. The big intake is a race version of the intake they are developing. This intake will require a ECU tune.

I'm waiting on a FI option, preferably a turbo, hence why I chose none

So if we agree that the reason an intake makes power is because it lean's out the A/F ratio.. Why shouldn't we all just go out an buy an SAFC? You can get them for $200 or less on ebay. Then can trick your car into leaning out the A/F even more than an intake.. probably make more power in the process.. and you get a neat little digital screen in your interior.

I understand what you are saying. But, I guess my preference would be to mod the car with more control and safety. Doing so by properly tuning the engine to add less fuel is better than tricking the MAF. By tuning you know exactly what you are doing and are in full control of the parameters. You set a proper building block for future mods as well.

Now having said that.. I'm not out buying a tune right now either. I think the current option(s) is too expensive.... way too expensive. I'll wait for a while until competition brings the price down. Anyhow.. sorry for the tangent.

I'm not claiming that an intake is unsafe or bad form. I guess I'm just bucking the trend a little bit. For years companies have been making millions selling us air pipes they claim flow more air and "allow the engine to breath better". I think a little differently. The engine is a suction device and the only issue to worry about with an intake is being below the restriction threshold.

Let me illustrate.. Pretend you are sucking air through a normal drinking straw. You can probably get enough air to breath, but not if you went for a run. So let's make that straw bigger.. say its the size of a 2' long vacuum cleaner hose.. Now you can get as much air as you want no matter what you are doing because you're well past the restriction threshold. Would your ability to breath be minimized if you curved that vacuum cleaner hose a couple times? No.. it's still easily big enough to give you enough air. If you can already get as much air as you can suck in through a vacuum hose to your mouth, would it be more helpful to switch to a pipe that is twice as big? Nope.. you already have no restriction, so what good would it do? I think Subaru and all other modern car manufacturers are smart enough to make that intake system easily exceed the restriction threshold. They know that people will let the air filters get way too dirty as well, so I have to believe they compensate for this potential by making all intake

Here's an interesting video: If you haven't watch might car mods, you should.. it's really entertaining. It's slightly different because they are testing the theory of "cold air intake" and we're talking about full intake redesign from throttle body forward.. but if you pay attention you'll notice that they talk about restriction as well..

One last disclaimer: I'm not saying that aftermarket intakes make zero power. I'm sure the design of the piping is slightly better than stock and I'm sure if you shorten the total path of the piping you can increase responsiveness a little bit.. I'm sure the simple design of the intake isolated from the a/f issue can make a 1 or 2 horsepower, or quicken response a hair, or at least make a better noise... which can impact perception of performance. So I have no problem with other people buying intakes.. I'm just not running out to spend $200 on one myself.. not right now at least.. maybe in combination with an FI system in the future or with a good tune setup, etc..

I agree with you 10000%. I agree for real with every single word you said. I just wanted to point out the leaning out was a byproduct of the intake (which I know you already knew as I've read other of your post and you are very knowledgeable.). You are absolutely right that the real benefit of the intake will be with a tune. Thank you for inserting way more knowledge into the thread than I did.

I was going to go with Takeda myself, but the way they handled dynos made me think twice. I'm not about to shell out 350 bux for a smoother looking stock intake, ya know? I'm going to wait for more third party unbiased dynos to appear, or until a company offers me an intake to do my own third party dynos... but we know that isn't going to happen.

While the car is under warranty, I'm keeping the stock intake and tune. Maybe when it's out of warranty and if I decide to keep it instead of trading up, I'll go for an intake or FI kit. But for now, it's staying stock power.

confused here. All I want is a little more power as I currently own a BRZ and jump on hwy ramps a lot.

From the graphs I've seen, it looks like these intakes lose power in certain areas. Are they all like this or are do the gains far outweigh the losses? WTF?

(sorry non-mechanic here, just using some common sense.)

Im waiting on APEXI!! Their filters are the bomb!!

Sadly I wouldn't count on them, when was the last time they brought out anything new to the market?

The injen one looks like crap!
I suggest everyone wait for AEM. They have been working on it for months. On a wide variety of cars here on the forum. Not just one frs and one brz in a weeks time
Seen their shop and design process so I know the final product will be top notch:thumbup:

None of the above, either PERRIN or TRD if they come out with one. That or whoever comes up with the CARB exempt intake first.

CARB exempt or CARB legal?

CARB exempt, although all items that are CARB exempt are smog legal.

Once an aftermarket part is smog legal it is given a CARB EO number making it exempt from emission control laws in California. EO stands for Executive Orders. You can read more info on it here: http://www.arb.ca.gov/msprog/aftermk...es/amquery.php

:thumbsup:

Ah, okay,

Yeah, the Injen intake is being submitted to CARB for certification. You should be able to get a CARB sticker for it, like all of their other intakes.

Have you guys been following the Airaid development thread?
http://www.ft86club.com/forums/showthread.php?t=8104

For the price that one looks like a sure winner. Injen has a nice looking system as well.

I have, but I prefer Injen's polished pipe, purely from an aesthetic viewpoint. :)

I'll wait for SRT's intake......

None right now. Until there's one that can be proven not to cause any lean or rich deviations from the OEM specification.

I want these to be effective mods but I struggle to believe the manufacturer left easy gains on the table. It would make little sense unless some last minute issues were discovered and a short notice type redesign caused restriction, interference or temp issues.

What would it take to prove that, out of curiosity?

Not sure. I know some people have the A/F ratio printouts that can show it. I just don't want something to affect the engine in a possibly negative way, wether it be within 1 mile or within 10,000.
