That last bit about A/F measurements before and after a part installation... I'm subscribed now. This has been extremely informative backed by real world results. That is an unexpected amount of detail and transparency. Thank you SOOOOO much for such a high quality video. Amazing job!!
I would really like to thank you for creating such detailed videos for the new gen twins. I also appreciate how everything is backed up by dyno data and how you explain such complex tuning topics in simple terms for the average joe. Thank you! Looking forward to future videos.
Thank you so much for all these scientific tests for the community. The difference in pipe ID at the maf area (yet giving similiar datalogged values) could be due to the stock maf being at the vena contracta area (ie the narrowing of flow just after every pipe entry) since its just after the "bell mouth" of the stock filter box. Thus the flow is seeing a smaller effective pipe ID (which happens to be the actual physical pipe/collar insert ID of the K&N. The community would love you if you can do this datalog test on the other competiting enclosed aftermarket air filters, eg AFE Power (which happens to have the maf also down stream similar in location to the K&N. Lastly, there is quite some talk about how the three (helmholtz) resonators along the stock intake track helps with bumping power at certain rev ranges (as opposed to just sound) but no scientific tests so thats something the community would appreciate for sure...
I did not notice dips or troughs in the powerband after putting the intake in. I played around with the resonators as well. However there are distinct changes in the sound of the intake without them at different rpm ranges.
@@stratifiedauto just the assurance i need to do away with the stock intake! Was afraid i will expose holes in the powerband when i remove the stock intake and resonators.
I liked the explanation of how a MAF works. Generally a six inch rule applies to having the tubing be the same ID and of similar straightness/curvature prior to the sensor. That is if you want to avoid a tune.
Glad to come across your channel and surprised to see that BC license plate! Just got my 2023 BRZ a month ago and looking forward to modding it in the next few years. Interested in your shop since you seem to specialize in the BRZ!
Absolutely. We will use it in time attack this year and for classing purposes and track purposes NA is best. But for a street car forced induction would be lots of fun.
Man, I don't know what you're doing with your mic, but it's buzzy as hell. Both the video from 6 months ago and this one. I don't know if you're clipping or if it's just a bad mic, but maybe try turning the input gain down and then boost it back up in post.
Hi, I can't figure out what the torque line is with the K&N intake. Is the highest torque line the one with the K&N between 3000 and 3500 rpm and between 5000 and 5500 rpm? I would like to understand if at medium rpm there was an increase in torque or a decrease
Are the blue lines for the torque? If yes, there is a sensible gap in some ranges (3000-3500 and 5000-5500) and I would know if the gaps are in favour of K&N intake or not (because I can't understand which is the line of the new torque). These ranges usually are the ranges of rpm you use the car on street, for this reason I'm interested more
For the sake of comparison, did the stock airbox have the charcoal filter removed? There have been a lot of videos showing similar dyno gains just from removing the charcoal filter. If these gains are versus the factory airbox minus the charcoal filter, that's awesome. But, if the factory airbox still had the charcoal filter it's possible that any gains are more or less illusory.
Have you guys tried removing the charcoal filter with the BRZ/GR86 on the dyno ? I've heard that just by removing the charcoal filter gives basically the same output when putting an aftermarket filter.
You guys should test the perrin cold air intake for this car. They claim that it has the same inner diameter as the stock intake, so it shouldn't need a maf sensor re-calibration in the tune. I'm curious if that intake has any benefits on a stock tune, or if you would still need a tune to see any benefits.
...basically, waste of money (as already proven by Australian & European tuners)... If you do it, purchase Perin intake - the filter is at the very front... O yea, there is an amazing sound... and that's it.
Did the stock airbox have the charcoal pad in it still? If so that is where your restriction came from. Most likely could have had the same gains for free removing the pad.

Thank you! As an engineer I find these details important.
I'm happy to see the gain, and I'd be grateful if you guys could do more comparison tests like other carbon intake system (GruppeM, Blitz, etc.).
If they send us an intake we will throw it on and test it.
It is not mentioned if the charcoal filter was removed from stock air box on first run.
Been waiting for this new video! Thanks for putting out more BRZ content!

@kiangloongng1322 did you happen to get the intake installed?
I would be curious to see you test the mst performance intake next!

Just got my 2023 BRZ a month ago and looking forward to modding it in the next few years. Interested in your shop since you seem to specialize in the BRZ!
Absolutely we can help. Give us a call!
will this intake cause a check engine light on the stock tune?
It will not.
Great video, sounds I'd pretty good but I daily my car and hardly even touch 4k rpm so I think I'll wait and do some other upgrades first!
Let me know if we can help you with those. We have extensive experience with the chassis.
Thanks for the great collection of videos on the gr86. I got the k&n intake thanks to you, but also bought the velosatech snorkel.
Good combo! Let me know if we can do a tune for you to tie it all together.
good efficiency in delivering the technical data. other youtubers take note. Get from Point A to point B and leave out all the conversational BS
Glad you’re enjoying the content!
would you consider turbo or supercharging the car? I know HKS is making a GT2 supercharger kit which makes around 300hp to the crank
Absolutely. We will use it in time attack this year and for classing purposes and track purposes NA is best. But for a street car forced induction would be lots of fun.
AH, the hockey puck mod! Thanks for doing these tests. Would changing the snorkel at all help with the power gains?
Perhaps something like a ram air would help but it takes away from the radiator and cooling stack real estate.

Torque was not affected much by the intake. It was all in the top end.
Are the blue lines for the torque? If yes, there is a sensible gap in some ranges (3000-3500 and 5000-5500) and I would know if the gaps are in favour of K&N intake or not (because I can't understand which is the line of the new torque). These ranges usually are the ranges of rpm you use the car on street, for this reason I'm interested more
Torque is in blue yes. The intake tube has high top end hp. The red line. They are darker.
So, both the torque (blue) and the power (red) lines with the K&N are the darker ones, correct? Thank you for your help!

Check our earlier video where we removed the air filter out of the stock intake.
Have you guys tried removing the charcoal filter with the BRZ/GR86 on the dyno ? I've heard that just by removing the charcoal filter gives basically the same output when putting an aftermarket filter.
No but we tried removing the filter altogether in one of our videos. That made no difference.

I'm curious if that intake has any benefits on a stock tune, or if you would still need a tune to see any benefits.
Would be interesting to see. It’s hard to imagine making a lot more power than this but won’t be able to tell until we test!
What header is that at the end?
JDL
@@stratifiedauto Do you know if they have optimised the piping for the new 2.4l?
Is this test with the stock exhaust? I can’t really tell in the video but it does sound aftermarket. Thank you.
Aftermarket full exhaust.
Thanks for the video!
I’m surprised to see a positive result, but I did it for the noise. Too bad the exhaust drowns it out.
You can definitely hear it in the cabin.
so is this intake relatively safe for owners that don't want to do ecu tuning?
Yes you can run it untuned as well!
...basically, waste of money (as already proven by Australian & European tuners)... If you do it, purchase Perin intake - the filter is at the very front... O yea, there is an amazing sound... and that's it.
It does add some top end power…
Agree@@stratifiedauto
Awsome review thanks🚀
Thank-you!
Great video
When will the EL header video be released. Would like to see the same el with cat and without as well.
We are editing it right now. Target is this week.
Metal intakes get hot. Plastic or silicone is much better.
We will be doing a little bit to mitigate the heat in the engine bay.
Great info.
Is that all K+N sound on stock exhaust?
The intake is loud I won’t lie. But it’s a very nice induction growl.
Did the stock airbox have the charcoal pad in it still? If so that is where your restriction came from. Most likely could have had the same gains for free removing the pad.
It did. We did testing on the stock intake removing the air filter altogether on the last video.
@@stratifiedauto yeah. But that little nubby hot air intake didn't do any favors.
How well did the box seal to hood?
Quite well. The mounts allow for movement so the hood acts as another mount.
Nice hot air intake
Once the hood closes it does shield the intake from hot air.
