You cant expect people to shell out another $500 for intakes without dyno proven gains vs a Stillen setup, otherwise stock for stock or with the same mods on the same car for an even comparison. Just my $0.02.

-We have done a comparison of stock intake verse our intake and the only mods the car had on it was a catback on our mustang dyno
-Saw 20whp increase (dyno results are on the first page or 2 of this thread)

I can absolutely see your point of view however consider the following....
Our products have always spoken for themselves and for our price your getting better intakes designed and tuned by someone who is a professional.

All of the other intakes including stillen, injen, and aem go for over $500 on there website and unlike theres we include free coding if you have an uprev or cobb AP, or your welcome to come get a tune. I dont see any other manufacturer of intakes offering that high of customer service in order to make sure everyone has a great set-up for there car.

Anyone who gets a set please put up a review!

Also a WAY Better design then Stillen.

You're offering a free tune, I know that, but does your tuner know enough to tune for every other combination of bolt-ons? At this point in the 370Z's marketed life, a large portion of owners already have invested in an exhaust, other intake mods... etc. Or are you only offering a tune if these intakes are the only mod? Also, Cobb dropped support for the VQ37.

Other than slightly different bends, I don't see how this design is that much better considering it still makes the same amount of gains. If it were truly a better design, not only would it be cheaper (not considering the tune), it would produce better power. Seeing as Stillen's primary market is Nissan, I don't see how you can necessarily surpass that kind of massive engineering manpower. Akuma is just entering the territory of the VQ.

First of all, it is not a real tune per se, but an adjustment to correct the fuel multiplier so that the engine will read correctly with the increased MAF housing diameter vs stock. My understanding is that there are no other air/fuel or spark adjustments. This is nice of them to provide though, although it is necessary as well.

I dont think the bends are a problem on the Stillen as it is quite straight before the MAF. The only "advantages" that have potential are the one piece design for looks and possibly a bit better airflow and the increase in piping diameter to 2.75" vs the Stillen diameter of 2.5".

However, we do not know how the diameter increase actually affects the overall power curve because we do not have a direct Stillen vs Akuma comparison with all other mods kept the same. This is why I mentioned a few times that we need that before people should shell out any money if they already have the Stillen Gen 3's.


Stillen has professional designers as well, although I do not doubt that Akuma does as well. Show us a dyno please with a direct Stillen Gen 3 vs Akuma 2.75" comparison to demonstrate the "better intakes" comment. If the Akuma intakes dont make more power, I dont see how they would be better other than aesthetics, which is a lot to spend $500 for. Nobody is bashing, we just need to see results vs your competition to buy into these at the price point they are selling for. The longer that people go without seeing evidence, the more they probably will think there is no supporting evidence. The same thing went for the Kinetix manifold for the 370Z which was never shown to have gains. Turns out, it did not make any gains, which is why Kinetix never provided dyno evidence to support their part.

Getting comparisons are always hard!

To get the most out of long tubes is tuning and a good shop fan! Evening road tuning if possible, closer to simulating road air temps/density helps get the most out of them.

Cause in the end a pipe is a pipe no magic vudu!

Yep, but we need them for sure on this similar of a product. A lot of us are very curious to see how the consistent 2.75" diameter affects the power curve. That will make a difference over the 2.5", we just dont know how specifically.

Exactly my point. Stillen's engineers are VQ masters. Not only that, but Takeda has also released their cold air, which is VERY similar, but offered at a slightly different price point. From what we've seen on forum member's cars, the gains are also very similar. I don't know about the piping on that product, but 2.75" piping will reduce intake velocity, obviously, and so it might make some difference.

Otherwise, I'm just gonna call it here and just say they're all the same damned thing. Pipes.

I'm just gonna add that the advertised gains on the group buy page was 8-12whp last week and has now been changed to 12-14whp.

Dyno will tell all. Maybe Akuma could send a set out to someone for a before/after dyno with other mods kept the same to avoid bias.

Seeing as they were previously trying to source a Z in NJ for doing comparo dyno runs, they would probably have told us if they reached a result. Since such a thing has not happened, I guess we're still waiting on legitimate, concrete dyno evidence.

They have a car for comparison dyno runs in NJ. Just waiting for the intakes to be done and I'll head up there so we can see the difference. I'm sure with Johns(akumas) knowledge and craftsmanship it will see more power then the stillen gen 3s! I have been to the shop and saw these intakes on a car they are specifically made for our cars with performance in mind. If John thought the stillens made more power he would have them on his Track car trust me he wants to go fast. I believe he made a better design and we will just have to see how it goes with the dyno, I'll be sure to post up the charts asap either way

We have concrete evidence of how they worked on a 370 with stock intakes and without stock intakes earlier on in this thread which i have mentioned already. The car we dyno'd was johns 2012 370z the first run is with an invidia catback and stock intakes, the second is with the invidia catback and our intakes which made 20whp over run number 1. If anybody has any questions i will be happy to post up the dyno sheet again to satisfy everyones concerns

We have no exact comparison to the stillens or anything yet only comparison from stock intake to Akuma Rev 2 Intakes
