I just bought my 2012 Blue BE last month. I am thinking about doing some light mod on my car. My first choice was P600 but I couldn't find anybody who could install P600 around my area(MD). Since AAM was near my area I am thinking about putting AAM 90mm premium exhaust, AAM midpie, cobb ap, E-tune and thinking about 2.75" intake or just HKS drop in filter. My question is do I really getting benefit out this intake beside sound without doing larger injector?? And I am also wondering how much power bump I could possibly gain with these setup. Also, If anyone has better idea for smilar setup please advise me. And please excuse my broken English lol..

drop in filter. The intakes dont really do anything and are not needed until you are going aftermarket on the turbos.

Not true. There is not only some hp/torque gains with a correctly designed intake, but also a increase is boost response. There is a reason Nissan changed the inlet pipe design on the 2012's.

Drop ins do nothing.

If you want to see some dyno sheets I can dig some up. Any of the long term members of the board have seen all the testing I've done regarding inlet/intake mods. The gains depend on supporting mods, and if the tune is customised for the changes that are made. A 2.75" intake is limited with the newest Cobb software, and with the right supporting mods can max MAF voltages at about 16.5psi just as the stock intakes do. A 3" intake will lower said MAF voltages and give headroom for tunes above 16 psi thus lending more horsepower to be made. The HP/TQ figures we have seen on the dyno with stock turbos would simply not be possible without a intake change.

+1.

There are definite gains to be had with intakes on stock turbos, especially large MAF housing intakes like the one made by Gotboost. I have the Akuma, but would have gotten his if he'd have gotten them out sooner.

But before going to larger intakes, I would go with downpipes and injectors. I think you'll get more gain out of the downpipes than intakes. After downpipes and injectors, then I would go with a large MAF intake.

I previously read on another intake thread that one of the possible downfalls with an aftermarket intake if less efficient air filtration then the stock paper filters. Is this still the case or have the more recently released intakes, gotboost for example, providing better filtration with the optional pre-filters?

I got them from gotBoost and I have the exact setup that you were looking for, shoot me PM if you want to check it out

Prior to releasing his intakes, Gotboost shared with NAGTROC the makers of the pre-filters, Outerwears. They make the pre-filters in just about any size/shape imaginable. I shared your concern about the aftermarket filters, so I got a set of Outerwears pre-filters for my Akuma intakes, which use K&N cone filters.

Just curious, why do maxed out stock turbo cars do fine with the 2.75" intakes if they're running significantly more than 16.5psi? Look at Sleepdoc for example. 19+ PSI and he ran consistent 10.0 times @ 136-138 MPH?

I don't want to change my downpipe and injector. Without those changed is intake still give better performance?

That was fine with the old versions of the Cobb software but the newer versions changed things and we were seeing MAF saturation way earlier than before in relation to boost levels.

I wouldn't have come out with a 3" version if it wasn't necessary.

BTW, I'm the designer and manufacturer for the Cobb intakes. They are really obsolete now if you want to run higher levels of boost........(like over 16 psi)

I'm currently running 3" intakes, 1000ID injectors, and full exhaust and I think in every respect this setup takes maximum advantage of the stock turbos and engines capability, I would recommend doing injectors and intakes together just as they allow a lot more freedom for the car to richen up at higher speeds (but there are better placed people to advise about that kinda stuff) I think it should also be bore in mind that downpipes and intakes allow your turbo to operate more effectively by removing the most restrictive aspect of the exhaust and freeing up airflow which both aids spool, temperatures and stresses on the turbo under normal conditions comared to a standard setup.

Here is some proof your statement is false:

This dyno sheet is from a customer......not me.

Green is before intakes, Red is after intakes, but not tuned for intakes yet, The customer said he ended up with 515whp after tuning.
