So I realize the whole cai thing has been debated to death, but I have a bit of a weird situation that I would appreciate any advice on. So I have a 2012 mustang v6 at with my mod list in the sig. So when I bought the car it came with the throttle body and k&n intake I just assumed it was a good setup however driving my buddy's 11 3.7 at with a similar setup to mine his throttle response and overall rpm band seemed better. Investigating this it seems the k&n typhoon intake is not so great even compared to the other small gains from other cai's and can make lower end throttle response suck. Apparently they took their dyno readings with the lid off the intake :( and their site has that in very small print and the metal tube seems to really heat up.
So it seems i need to replace this btt I have none of the stock intake parts, other then what the k&n re uses, I do have the stock throttle body though. I was looking at getting the car re tuned for 91 from steeda(free tunes) since they finally got no corn 91 in my area. So my thought was maybe putting on the steeda cai since I have their tunes, however I dislike the fact that since you have the larger maf housing you can't octane tune down without switching the intake back out
So it comes down to buying a new cai from say like roush or airaid, trying to get a a factory intake setup and installing or just getting the steeda and 91 tune and hope I don't need to put 87 in again anytime soon.
Anyone have any advice on a cai they like ? Seems from what I have read the cai provide very little over factory without a very specific tune, and the steeda cai pretty much requires 91 and their setup which could be an issue down the road.
I'm really surprised k&n would pull a afst one I've always had good luck with them in the past, but guess the 3.7 is a much more modern engine.
Thanks for reply's

I also have a 2012 V-6 that I bought used with a K&N Typhoon intake already installed. I added a BBK throttle body and shorty headers. It still had poor throttle response until I got a 93 octane MPT tune and my throttle response and power is fantastic. The Typhoon does not hurt anything it is the stock tune that is messing up your throttle response. The Typhoon with the lid on gets cold air from front intake just like stock and there is nothing better. Don't bother with a new intake it won't fix anything. Spend the money on a 91 octane MPT tune instead. You will not be sorry. They have been tuning Cyclones forever and no one beats them AFAIK.

^^^^^^^^ This Exactly ^^^^^^^

Your throttle response increase came from the MPT tune. Changing the TB and intake probably hurt the throttle response. MPT tunes have given me better throttle response than any other tunes I’ve ever used except Dyno-Tuning (in person, on the spot, and expensive). I’ve had a ton of different tunes, and MPT was by-far the best of them all for a naturally aspirated setup. MPT specializes in v6 tunes btw.

If I were going to replace the intake, I go back to stock (including the TB), then get a SET of MPT tunes and carry a tuner in the car. Then, on the off-chance that you can’t find 93, 91, or whatever octane in your current area, just load the appropriate tune and keep rollin’

Well it does seem on newer cars the tuning is the main thing. I have heard goods things about mpt on the forums, I originally went with steeda as they advertise as the "safe tune" but even they admit they are a bit conservative.
Assuming paying for 2 tunes mpt could probably make a 87 or 91 tune , that takes advantage of the throttle body and intake under both circumstances or at least doesn't need the swap to the stock setup and switch back assuming fuel drained and switched.Or is truly the stock setup isn't actually that bad and a tuner can make a more streamlined tune with those ?
For the record my daily drive is 110 miles highway overall, in the morning at 4am I can really open her up, but in the afternoon with traffic and semis blocking both lines, i'm lucky to keep the cruise set at 75. So I need a tune that still maintains decent manners.
Thanks

This is indeed the case, you won’t see any improvements here unless you have made other modifications. On a stock late model engine, the CAI is just for looks mainly. The difference is in the tune, and it’s quite safe from MPT.

Thanks for the help it's funny how cai and throttles are always pushed as the best basic starter bolt ons, but yeah it really did seem like my buddy's had better response then mine and that's considering I have a tune. I don't plan on doing headers on the manifolds as I don't want to crack the engine open at this point, so it does make sense that the cai and throttle really aren't making much of a difference since the manifold vacuum is the same force all the air in you want but if you don't have bigger ports it's just gonna push it back out and might even create turbulence in the airflow.
Seems like a stock setup and good tune and the suspension and chassis mods are the way to go. I know my borla cat-back is purely for sound but boy does it sound awesome.
Then again i was taught on old chevy small blocks and a carb is really nothing more then a toilet bowel with adjustments.

This is the way to go …

A bigger intake tube doesn’t put more air in the engine in this case. The engine can only draw so much air, and the stock intake already exceeds the Max CFM the engine can ingest. Yes, a CAI often disrupts laminar air flow and makes tuning more difficult and can cause stalling sometimes.

You can do things that make more power and low end torque besides a tune. I still have a set or ported intakes I need to install that can add 25 HP. The Cyclone engine is very responsive to mods that allow it to breath better. The Cosworth heads flow very well stock so anything that gets them more air will show up as power.

That video gave a very good example of how important a closed air cleaner is to the engine. I have alway kept the lid on my K&N and it feeds air from the stock intake through the grill.
I also have a 2012 V-6 that I bought used with a K&N Typhoon intake already installed. I added a BBK throttle body and shorty headers.

The best thing you can do for your car is change the gearing. Your car comes stock with 273 gears. I have a 2014 mustang V6 and swapped out my stock 273 gears for a 355 gear set up. Night and day difference. I did not want to go to 373'3 or 410's because the 355's are a good balance of off the line giddy up and go and still having a lot leftover on the top end. Good luck, Denny Mangano.

This is true but my Stang came with 3.31 GT gears option from the factory so I am keeping them. Changing gears can be problematic judging from what I have read online. If they are not done right they can be really noisy.
crjackson - You were right 100%. Switched back to stock throttle body and intake with the steeda tune and a lot better response, didn't feel like I was fighting it get up to 3k rpm's. Got both a 91 and 87 mpt prx tune setup , mostly just gonna run the 87 but a lot cheaper to get both at once.
When to comes to the tune though even 87 all I'll say is dear god, don't know what magic sauce mpt has, but MPT makes the steeda tune seem like a slug.The throttle response is so light, I'm actually having to remind myself I don't have to push down hard or I'll rear end someone. I didn't get a whole lot of time to test cause of course we I am we get snow in May, so just a light trip round the block but again dear god, those guys know what there doing. I did like my steeda tune for the most but it honestly doesn't compare.
Appreciate all the advice and post's, I'm quite happy with how things turned out.

I actually switched to 3.31 from my 2.73 as I wanted to stay in a factory ratio , and it's a good daily driver ratio. But yeah my mechanics had to install ford racing ones 3 times and couldn't get them to stop squealing, and they marked shimmed them etc.. even brought my back to watch. So we switched to a a ford oem replacement since it's a factory option set and 0 issues. Guess the racing gears have a hardened surface and are known to be a bit noisy.Fortunately for me they are awesome guys and only charged me for one install and set of parts.

@crjackson - You were right 100%
Glad it all worked out. MPT is a great group.
