There are several other dyno videos showing 5-10HP from charcoal filter removal. There is more to an intake than just slapping a filter on a tube. Intake resonators that tune vibrations and harmonics are a real thing.
Tested with OEM filter, high flow filter and removed the filter altogether. You’d think if the air box was a restriction you’d see something. However if you wait a few hrs between pulls the first pull will generally read highest. So when you’re talking about a few hp you have to be pretty methodical.
@@wayward03 i think it will perfome more than 10% because they are free hp with same wieght .. any ways waiting for the numbers ... I dont know why they dont show us 😒
@@stratifiedauto I don't think anyone was expecting 30whp from an intake. But there has been dyno runs w/o the carbon filter that has showed some gains with stock filter. Itd be nice to have another data point, even if it is just 2-3 whp at 8k rpm lol
You still have the accordion intake tube. Gotta get a smooth one. Then the real purpose of an intake will show, which is throttle response. Not horse power or air flow. Along with a throttle body port, it's worth it to me
You should try the charcoal delete, i have seen this subarus getting up 10hp only by the charcoal delete... you can say that the "conic" air filter does not have any charcoal delete, but i really think that the stock airbox is a lot better than a conic filter on a stock engine aplication...
should of done the K&N filter without the carbon filter that restricts it alot..and the stock airbox willl keep the air cooler over the 3d printed intake,.
My 86 came with a KN, i put a std filter there instead, dynoed less hp with a KN on my other track car, so it has OEM filter aswell. OEM doesn't look cool but works well in many cases :)
@@stratifiedauto my track car is actually 40years old, bur porsche made the filter very big and with lots of folds/filter area, Which apparently worked well :) Though for sure not all old cars do that.
What is that carbon doing and why is it tied to compliance? Is on the intake so it is taking air out of the environment, not exhaust, I don't understand the reason of carbon before the engine, there is nothing to clean on the intake.
All this talking. Didn't tune the car at all. Before or after. Even though its been shown again and again that the car like the Gen 1 learns and goes back to how it was. It's the 2020's not the 1990's!
Since my tuner said "lack of oxygen" was holding me back (from more than the 226 corrected HP) I'm working on getting cool air in without using a snorkel from the radiator area (and blocking some of the radiator). I have a 3" aluminum tube going from the box/MAF to the throttle body. I will insulate the tubing. I already have gold reflective tape on the box. I have cut a rectangular hole in the fascia so air can go straight into the airbox through a fabricated rectangular tube.
Can you try and make that intake to not get heat soaked? I'll definitely buy one just for that induction howl. I'm not worried about making more power. I just don't wanna lose any over stock.
@@stratifiedauto I for one would be interested to see what the difference would be using the Technocraft intake resonator blockoff, and a post-MAF silicon hose, those together plus removing the charcoal filter and using the k&n filter should be the equivalent of a full cold air intake
Well, the air filter restriction is not really a problem for pretty much all modern engines. So the power/torque gain from intakes comes a lot more from having the air flow in more efficiently and not carry up heat with them from other sub-systems (manifolds, even the engine bay itself is a pretty warm region compared to where the air feeds of the OEM-like intakes take the air from). So larger open-filter intakes may gain sense when the power output is increased by a lot or some specific goal is on the list (sound).
Some intake manufactures on MAF based cars also play a little with MAF housing size to adjust what the ECU is seeing, read less airflow and gain a bit from this ECU reading offset.
@@stratifiedauto thanks for the reply! I tried a Diono 3RX but there’s a gap between it and the BRZ seat cushion at the back. I also tried our Britax Grow With You ClickTight Plus Harness-2-Booster but the base on that thing is too wide. Are there any tricks to getting either of your seats to fit? Thanks!
I actually went for the smallest seats and did research on the Porsche forums for small base seats. The 3 stage seats or seats with things like cup holders won’t fit well. Maybe I should do a video on fitting car seats.

Great video! Thanks for comparing. Looking forward to a potential carbon filter video.
The hood supposed to be down (with K&N filter)
I was excited to see 0 - 60 time... I mean that way i will understand how much performance is gained .. anyways thanks for the great contant 💪
I think you'd need a 1/4 mile to show much.... the most I've seen is 10% which is noticeable but not night and day.
@@wayward03 i think it will perfome more than 10% because they are free hp with same wieght .. any ways waiting for the numbers ... I dont know why they dont show us 😒
Love how honest the tests were. Keep it up.
Really I appreciate your review and information 👍
Thank you very much.
Please Keep up with more updated and videos
To get more power all you need is header,midpipe and tune
Looks like it so far.
Do without the carbon filter
The gains will be similar to what you see with the intake. A couple hp.

Would you recommend the grimmspeed post maf hose?
Subscribed because of this video
You will love the next one ;)

For modern cars the intakes are pretty well designed.

Soaks up fuel vapors coming out of manifold once car has been shut off.
@@stratifiedauto ok that makes sense

Yes this was all tuned for and datalogs verified for consistency. The MAF housing we built is identical to OEM to not throw readings off.

More air, cold air, always helps. Engine is an air pump. Making flow in and out as efficient as possible is key.
tell me you got a scoop or the GruppeM??? lol

We will be trying just that soon.
I regret so much, I bought the carbon fiber half-open intake before seeing your video😂
It probably sounds nice.
The BRZ/GR86 is advertised 170KW in USA and 174KW in Australia. The extra 4kw is the charcoal filter we do not have :)
Video next week will reveal more :)

How much did the overall tune net with the mods in the test drive?
Have a look at the previous video where I cover the tune in detail for pump and e30
I'm excited to see the potential of the newer 86 platform
It’s quite good!
will an aftermarket catback makes a big difference or keep it stock but go catless?
Catback adds a little. Most of the power gains are in the header and tuning.
Really excited to get that e85 tune at your shop last time i was there your guys are still sorting things out to move the dyno to that bigger space
Car sounds great is it an el header?
Uel in this one.
How much calibration did that MAF need with the intake on it?
We sized it to OEM spec. So none.
@@stratifiedauto that speaks to the design and how stable it keeps the airflow over the sensor as well. 👍

What car seat do you guys have in the back? How well does it work?
I use 2. A maxi cosi rodifix for a booster and britax emblem for my 7 and 3 year olds. They work great and yes the BRZ does school runs no problem.

You said do do
7:26 💩🤣
Would love to see y'all Dyno the MST cold air intake. It has an open top that seal with the hood.
If they send us an intake would love to test :)
If you want power, engine swap or Forced induction
Sure, and for some it will be up their alley.
