Has anyone removed the charcoal filter above the air filter? There are so little posts in the Mazda community, but this in the Subaru Crosstrek community is a must do.
The few posts I have read, talk about it improving sound and giving nominal gains in horsepower

I will now make your charcoal filter disappear.

>POOF<

Now go check your intake box. Like magic, the charcoal filter is gone!
While I'm at it, I am going to go ahead and lubricate your muffler bearing for you. Done.


You could always try one of these!

I am completely kidding by the way. I am amazed those things still exist.


There are no (cheap) magic solutions to power increases on these (and most) modern cars. Gotta spend money to make moar faster. For the Mazda 3, the best bang for the buck (and most essential for any additional gains from additional bolt-ons like exhaust, intake, etc.) is an ECU tune via Orange Virus. Just the tune alone before additional bolt-ons, you can gain 15-25 (proven) HP. Bolt-ons can provide further gains with additional tweaks made to your tune. Expect minimal to no gains (maybe even loss) in power with bolt-ons not accompanied by a tune.

Yeah on certain cars in market areas that are ruled by nutso socialists
(cough cough California cough cough)
However they're doing it, they've managed to sell automotive snake oil for over 20 years! I am willing to bet a lot of those sales are people who bought one purely out of curiosity (despite their skepticism), popped it in and either realized it was junk and tossed it, or simply forgot it was even in the car and there it remained until a mechanic found it and told them what a piece of junk it was long after the return period had expired. Brilliant business model!

Actually the charcoal auxiliary filters are OEM, part of the PZEV system. Its there just in case a stray microgram of benzene should float up through the intake when the car is not running and try to escape into the outside world....

Muffler Bearing and Tornado Air??............ Good job kid

Cars in California and where CARB is taking over HAVE (you should go check) a secondary carbon filter above the Air Filter under the upper lid (As Arathol said) OEM to keep gas Vapors from escaping when the cars are turned off. It is for a PZEV rating.

Its not for the minimal of minimal HP increase, though mainly for the possibilty of higher fuel economy and since I have a manual transmission I would love an extra decibil of noise telling me when to shift gears as I have for so many years, without having to go ricer and install an intake or exhaust

Uh, isn't that what the tach is for?:|

Theoretically yes, but you can't really watch the tach and drive at the same time.......If you have been driving a stick long enough you know when to shift just by listening.
Paris Im assuming you drive an auto and let the car do it for you or really new to manuals. The ability to precisely hear the engine tone allows you to shift gears properly without having to look down and left everytime you shift FFS.

I assume by referring to me as 'kid' you are trying to insult me and have therefore completely missed the sarcasm (and the additional comments taking into question the continued existence of such a ridiculous product like the Tornado Air). I did, in fact, state below that comment that I was actually kidding. And since you are the one asking about the filter and it requires not a single tool to open the air box, YOU should go check. I have opened that airbox many times for one reason or another and never once was there a separate charcoal air filter.

I will admit I have never come across a charcoal filter in any car as all my previous experience is pre charcoal filters (and my 3 doesn't have one either despite being a newer generation of automobile!). So this is something new I am learning! As Arathol stated, "Its there just in case a stray microgram of benzene should float up through the intake when the car is not running and try to escape into the outside world", it is in fact for CARB jockeyed states like CA. Personally I'm waiting for the day they put charcoal underwear on cows. I have heard their gas emissions can be detrimental to the ozone layer as well. ;)

I also will not argue with you about the increase in engine sound being beneficial to driving. ONE of the reasons I put a custom exhaust on my car is because I found not being able to hear the engine when I heel-toe was due to the fact that I could not audibly hear my RPMs over the road noise ( and my deteriorating hearing ). Now, after a throttle remap to get rid of the lag, plus the added noise, my downshifts are as good as they were back in the cable throttle days. But, lets be honest. Most kids put a loud exhaust on their car for the sake of farting loudly around town and because their friends all say it'll add 15 horses. And most of them drive automatics anyway so that just further proves the point.

What triggered my smart-assness probably has to do with the fact that so many posts on this forum would be answered by doing a little leg work (or searching). It takes minimal effort (as you are already at your computer) to Google (20XX Mazda 3 charcoal filter, intake filter, CARB weenie filter, etc), OR you can walk to your car, pop the hood, pop the two little clips that hold the airbox closed and take a look for yourself! You could even look for that PZEV rating or whatever on your car. A sticker? Maybe a logo somewhere? I dunno. If all else fails... ask Siri!

I'm no fogey, but I am definitely not a kid. I just have sarcastic tendencies. Now, with all due respect, get off my lawn, Junior! ;) I'm done ranting.

I bought my 2018 Mazda3 brand new in California (Touring sedan 2.5L 6spd MT; made in Mexico) . It also does NOT have a charcoal filter in the airbox.

I picked up on this and thought I was just imagining things after I tore mine's out. I haven't done anything else to the car, until installing my RMM today.. but I like the tiny uptick in noise it makes. Totally unnoticeable to the casual passenger.. You'd have to turn off the infotainment & drive on a fairly smooth road to even hear it.

This is interesting, thank you for sharing your experience. Does the car make such a noise that you can't hear the radio? By the way, there was an unpleasant smell in my car (a musty smell of dust, if you know what I mean) and I thought that if I change the air filter, it will somehow help me. But I was wrong. Later, I watched videos on YouTube about how to get rid of this smell in the car and I learned that ozone generators do a good job with this. If you know anything about this, please share it with me. So, I read a bit about them on damagecontrol-911.com and realized that it should be used carefully to avoid problems.

No you probably won't even notice the uptick in noise unless the radio's off. I don't listen to radio/music when I drive so I noticed it right away. It's a very muted subtle increase, I actually wish it was a little louder. If you're driving on a old/badly paved road, the road noise will definitely drown out the engine/intake noise.

The ozone generator helps to remove odors, bacteria, and viruses. It's recommended to turn on the ozone generator from 30 minutes to 2 hours. After that, you should ventilate the car. Frankly, I don't use an ozone generator, but I've heard it's a good thing.

You may be confusing the engine air filter, and the cabin air filter.

How long have you been driving manuals? I rarely look at the tach once I’ve driven the car maybe 5 times. You have to look at the road and listen to your car. It’s part of the general reason people still drive and love a stick-shift. Not to get too Japanese on you, but you have to be “one” with the car.

An ozone generator is unnecessary. The easiest way to fix this problem is keep your air on, but turn the AC to just fan for the last couple of minutes of your drive. Do that a few times and it should be fine for a month or two. If you start smelling it again, repeat. It’s mildew building up from condensation in your AC ducts. Or pay for the ozone generator. Either way the problem will return within the same time period. 🤷🏻‍♂️
