Not surprised by the stock filter vs K&N. This isn’t 1999 anymore… a good quality paper filter can flow very adequate, enough to negate any power advantage of aftermarket drop-in filters.
@@martinrps13 yeah but, K&N allows more dust and sand particles to get into the engine, and for the price of a K&N filter i can buy 5-6 normal filters that will last me about the same nr of miles as K&N recommends to use their filter.
@@martinrps13 there is a video on youtube where a guy test K&n vs other air filters. Performance Air Filters - K&N vs AEM vs BMC - DYNO TEST is the video title
Awesome video man, good to see some gains. Fun story, my friends old 2001 forester picked up huge. Last summer he called me up saying it was running weird slow and sounding funny. Between the 3 huge vacuum lines pulling crankcase back thru the stock intake, and it being SOOO heat soaked, it was literally recording 65 degree celcius intake air temps at part throttle, and like 55 at WOT. It was pulling all the timing it could and still detonating its ass off. I put some piping onto it, put a cone filter in the fender well and added a catch can. Thing was recording 30 degree intake air temps at crusing and 28 WOT on the SAME AFTERNOON
Experimenting with new cars like this is fun. You never know what your going to learn. Some things you change may do nothing and other thing can be revolutionary. You never know. Awsome video.
yes, and the new 2.4L seems like something decent for modding. ive seen enough people with mostly stock bottom (changing the headgasket) on the FA20 push 300-400whp which is more than double its own output. this engine supposedly has stronger internals as the FA20's problem was that the rods were skinny and angled for easy assembly
You saved me 60 bucks sir thank you! I was considering buying the filter for some gains that i read on forums but im glad to see videos of proof for myself
Excellent video man! You just made a ton of 2nd gen owner really happy 😂. Can’t wait for a legit intake to be made, or at the very least do this to mine
@@Eugen-Eat 13% loss ratio that is 29.094+223.8 that is still over 250 infact 252.894hp to be exact pretty good for stock car with a simple intake hack this car with full bolt on and a tuned will do 280 fly wheel hp which is honnestly just about perfect for a back to basic front engine rear wheel drive sports car.
@@patthonsirilim5739 No, even with FBO it will never do 280hp ))) the fact that he uses an inertia dyno confirms the numbers are a bit inflated. On a retarder type Dyno like Mustang these cars make under 210whp completely stock. An air filter doesn't have any effect.
Love the testing. Def worth removing the diaper lol, kinda surprised the k&n did nothing but I'm sure the engineers used a good flowing stock filter being a sporty car. Def a Toyobaru, the engine cover, air filter and engine/exhaust sound confirmed its not a typical Subie boxer. Lol
I have to assume these runs were done in 4th gear which is not 1:1. I recently had my 22 brz with charcoal pad removed, catback and front pipe on a dynojet and it made 205\165. But that was in 5th gear. All the people going around saying how these cars are so underrated are doing the dynos wrong and getting false high numbers. It seems to be a trend across the board, not just with BRZ\86s.
What exhaust is this guy running? It sounds really good. Edit: looks and sounds like a Tomei later in the video.... DAMN man lol. I know it's gonna be too loud for me IRL.
I think the gr performance filter is just a k&n filter rebranded, or functionally equivalent. Someone on the forum that got one said the maintenance instructions were to use the K&N filter cleaning solution
It makes you wonder if that filter membrane is something there on purpose, meant to be deleted for "special editions" that gain a few HP as part of the package......
awesome video, are there any cons to taking out the charcoal pad? is there any benefit keeping it for a daily driving car/protect it in anyway? Thanks!!
Pretty sure it's just a dumb American requirement for emissions reasons... But it doesn't actually reduce emissions. This is why USDM version is officially stated as having 228 hp, while the EU version is 234
Yes, the engine is underrated. Toyota's 4-cylinder GR Supra makes 255hp, they can't advertise a GR86/BRZ making roughly the same crank power while costing $17k less, so they lowballed it to 228hp.
Nice work showing that a high flow filter doesn’t always mean more power, still like them for their washing ability which saves money later. But I know these cars have a quiet induction noise, did the K&N improve the intake sound a little?
The active sound is still on so no noticeable induction sound increase at least to my ears. Removing the 1-2 (baffles/silencers??) on the intake would probably be more effective for that.
@@solly1g that's a resonator on your intake. Yeah it reduces intake noise but it also softens the air hammer that happens when your intake valve closes. If you delete the resonator, you'll get more intake noise but you'll also get less air in every rpm range. They actually help performance
@@HunterTuned I'll take a set I message u on fb as well. How u want me to pay ? Threw website or cash app ext? And there 14mm injectors right? Toop feed 2200s
I took mine out and after about a week I put it back on. Felt like I lost throttle response after the ecu adjusted itself. It’s possible that you’ll get an Hp increase top end but seems like you’ll suffer low end. Maybe messes with the maf/throttle mapping…not sure
33 view... haha. Man did you see the boosted boys kswap a frs. Used the stock frs trans and all... with a/c... should check it out. Maybe build one or something
I wouldn't recommend removing the diaper for warranty sake and also it would lean the engine out a little bit due to the MAF not being recurved. Depends on how rich they tune these cars. Although, I can see where down the road when these cars get more miles, that part is going to be an issue. Why would they even do such a thing that may lead to another clog? Noise dampening (smell dampening) or no, that is what is called over-engineered. A new intake with tune would be the way to go for sure, unless your dealership is a butthole for any aftermarket parts. LOL Nice info though!
100% wrong on everything you said 😂 the filter does not effect warranty in any way shape or form and removal of it will not change your MAF reading only changes in the diameter of the intake piping where the MAF is placed will lean out your fuel mapping due to improper MAF scaling 🤦♂️
who told you this. this is a 2022 car not a 1984 vehicle. the computer knows exactly what fuel/timing/air. If you go up or down in elevation does the car lean out? no lmao because it has a computer to make adjustments. foolish comment you must be old as hell
Good to see some actual dyno runs for these kinda mods!
With a car this light I imagine every hp is more noticeable.
Not surprised by the stock filter vs K&N. This isn’t 1999 anymore… a good quality paper filter can flow very adequate, enough to negate any power advantage of aftermarket drop-in filters.
Put some miles on both filters and then you will see why the k&n is worth it….flows better under restriction due to contaminants
@@martinrps13 yeah but, K&N allows more dust and sand particles to get into the engine, and for the price of a K&N filter i can buy 5-6 normal filters that will last me about the same nr of miles as K&N recommends to use their filter.

Not only is the charcoal filter a restrictor, but its not replaceable. So eventually it will become MORE of a restrictor and become more clogged
It's not often that I lol at a car video, but you did it. Nice work man, you're a funny guy. Not like a clown.

Sweet! And fun to see another who has those MN/WI plates. Thank you for posting
Just goes to show how a lot of these companies claim that their products make more power when in reality it's the damn charcoal filter 😂
Do one of these for the grimmspeed post maf hose if you want/can. I wonder if the combo of k&n+removed charcoal+tube will give more gains or not.
The D4-S (dual injection) system belongs to Toyota...the rest of the car is Subaru (minus the rear suspension differences btwn the two cars)
Minus the body as well, Subaru designers never come up with a very nice looking car.
Excellent video man! You just made a ton of 2nd gen owner really happy 😂. Can’t wait for a legit intake to be made, or at the very least do this to mine
I just got one of these a couple months ago and I’m super happy to take the diaper out of the air box 😂 [how’d that get there!?]
Thanks for the true look at intakes
I take out the charcoal filter on all my cars. It's just to eliminate smell/emissions after you turn the car off.
223.8 whp is very good. That amounts maybe a bit over 250 bhp (15% trans loses. Others calculate with 18%)
18% are for AWD automatic. A manual RWD would be like ~ 13% loss.
18% is too high haha

...is it easier to gain hp (w/o going tooo crazy) or lose weight throughout the car? both cost money and gains are minimal
Those new brz look pretty good. Great job as always brother. 🤙
Same with GR86, they're lovely cars!
"Do you think any vape clouds will go through this?" I'm dead lmao
My 2006 V8 Lexus has the same weird charcoal screen. I may be rippin' that thing out this weekend.
It's a Subaru engine with Toyota D4S fuel injection system. Direct and port injection.
Just running stock airbox and filter and a cold air snorkel on mine. 👍
Love the testing. Def worth removing the diaper lol, kinda surprised the k&n did nothing but I'm sure the engineers used a good flowing stock filter being a sporty car.

theres people with the stock intake box on the FA20 pushing over 300whp. not sure what advantages this would give
@@invertedv12powerhouse77 best one sis corsa it adds 20 hp 19 tq if tour tuned but its illegal in most states 😭
I wonder if taking the diaper off ruins the factory warranty.
hah!) thank for charcoal filter tip!!! didn't notice it's there))) jdm's didn't getting that one!
I’ve seen people take the snorkel in the bumper and make it bigger for more air
I'm waiting for green filter to make a air filter for the 2.4 brz
Is that wheel hp? Because Toyota/Subaru claims 228hp
They should give an factory option for no rear seats - they are useless weight addition because they are never used!
Seibon made a carbon fiber rear bench delete that looked slick. I assume they will make one for the 2022 as well. They've already got cf hoods ready
Great video! Thanks for making this.

Thanks so much!
BRZ has Subaru engine with Toyota transmission
And Toyota injection, because Toyota is famous for it.
@@roboticvenom1935 yessir
What do those charcoal pad filters even do anyways?
Thanks for the vid. Do you know if the stock filter was like a GR performance filter they advertise or just “stock”. Thanks
Was stock whatever the factory came with when it was on the assembly line
I think the gr performance filter is just a k&n filter rebranded, or functionally equivalent. Someone on the forum that got one said the maintenance instructions were to use the K&N filter cleaning solution
what are those wheels size?
Does anyone know if it ends up throwing any codes after removing the charcoal filter?
Nah its pure for emission only, won't throw any codes at all
would removing the charcoal filter void the warranty tho?
Not sure.
No.

Thank you very much for your Test and information.
I have a question please.
What was the temperature outside at the time of the dyno?
Did you get a check engine light after removing the diaper?
No
Is that wheel hp? Because if so then thay is a huge difference if the stock is 228 crank hp no?
Yes, the engine is underrated. Toyota's 4-cylinder GR Supra makes 255hp, they can't advertise a GR86/BRZ making roughly the same crank power while costing $17k less, so they lowballed it to 228hp.
When I took out the "stock" filter, mine says "GR" Filter and it looks almost identical to a K&N Filter... I have a premium trim GR86
Subaru doesn't have that!
218 at the wheels? Seems like these might be a bit underrared from the factory.
They are, otherwise they wouldn't be nearly even with slow WRX STI's(literally watch them on a roll race it's so sad)
@@roboticvenom1935 Yes. I've seen that. Was quite surprised! Though, it makes sense, the WRX is like, what, 700lbs heavier?
K&N Filters rarely provide much horsepower, but they do filter significantly worse than normal filters. They're not worth running.
I had a 1st gen BRZ, glad I got out of it before the market started going down..
What you got out?
What the hell!? Why toyubaru would put such a weird restriction? Those are basically 2 filters!
The charcoal is so that fumes don’t leak out into the environment out of the airbox
A lot of it has to do with noise and turbulence. Induction noise is one thing companies try REALLY hard to keep quiet.
Toyota GR86 has a "GR filter" that's superior to cheap one Subaru uses
But as someone who just daily drive this car, I don't think removing the filter is necessary as I don't see any real changes at lower RPMs.
Everyone is saying this car, along with many other modern cars, don't respond hardly at all to intake mods. I never understood that.
Nice work showing that a high flow filter doesn’t always mean more power, still like them for their washing ability which saves money later.
But I know these cars have a quiet induction noise, did the K&N improve the intake sound a little?

I took mine out and after about a week I put it back on. Felt like I lost throttle response after the ecu adjusted itself. It’s possible that you’ll get an Hp increase top end but seems like you’ll suffer low end. Maybe messes with the maf/throttle mapping…not sure
@@mizzta21 that’s interesting, maybe I’ll just go for a drop in filter since Toyota offers a GR branded one.
