REVIEW: Simota Carbon Charger for a 2010 Mazda 3 (2.5L engine)

Recently I had the opportunity to work with Gary (protephile on M3F)@ West Imports. He was looking for a Test Fitter for the new Simota Carbon Charger for the 2010 Mazda 3 (2.5L). I have a 2010 Mazda 3 GT 6 speed, and have been with M3F since shortly after the 1st Gen came out way back in 2004. I never had any firsthand experience with Simota, but on the Internet and this forum especially they have a trustworthy reputation with their products, so I jumped at this opportunity. Plus it gave me the chance to own the first one available in North America.

So after working out some details Gary promptly shipped me the kit, as seen here:

It comes with everything you need to install the system on your Mazda 3. Once the stock system is removed, the Simota install is very easy, and it comes with directions. I have also written up a more detailed set of instructions, for someone that has never installed a system before. I feel the write up should help people save some money by being able to install it themselves, plus it is fun working on your own car. Instructions thread:

As for the install, it was very easy as I mentioned, the kit comes with everything you need. The quality of the parts is excellent and everything fits properly.

I was a little worried about the Check Engine Light coming on after the installation, even after Gary said that it would not. And of course he was right.

I let the car warm up properly, checked for leaks, found none and took it for a nice long drive around 1 hour 30 minutes. During the drive I tried a lot of different speeds, at cruising speed the intake is not heard. Only at hard acceleration and high RPM driving can you hear the intake. I have had quite a few cars with intake systems on them:

2002 Eclipse GT, Dodge Neon, 96 Grand AM, 2000 Hyundai Elantra (same engine as a Tiburon), 2000 VW Jetta 2.0 and a 2002 Jetta 1.8T.

The intake brands have include K&N, AEM v1 and v2, Weapon R, Generic and of course Fujita. This is my first experience with Simota, and I must say I am very impressed.

The sound is great, and the added response is great. I know a lot of people myself included have commented on a "dull" spot in first gear, it's kind of like a little lag. After the install of the intake it is nowhere as bad. Obviously don't have access to a dyno, so I cannot comment on real numbers, but you can definitely tell that there is more there, and the intake makes the 2.5 sound like it is supposed to.

PROS:
-The ease of install and fit.
-The sound.
-The response of added power.
-Price of a brand name component.
-A great salesman, well I guess that isn't related to the intake but Gary knows his stuff.
-AND the BIG one, No CEL (Check Engine Light)

CONS:
-The filter support is a little tight but can be adjusted slightly (nothing major)
-And if you aren't careful, you can scratch the CF filter cover with the metal support (nothing major).
Nothing is perfect that is why I listed CONS. But as you can tell they aren't anything major.

If you have any questions let me know. And in talking with Gary, we thought it would be an excellent time to do a group buy on this product. So for questions relating to that shoot him a message, as he is easy to get a hold of.

very interesting! i'm glad to see more products coming for the car. adds a little variety, and i've not seen this brand before but it looks very nice. i have a couple questions/concerns that i'm not sure you could/should answer as i'm not trying to put you on the spot. does the dev of that device visit our forums? i see that he's on M3F, as you said, and i only ask as CS is always on these boards commenting, etc.

i know you don't have the dyno numbers, but does the company that made the intake? CS had very detailed numbers, noting differences with heat in the engine bay (heat soaking, etc).

also the carbon fiber looks great! but how easy it is to change the filter? it looks quite encapsulated.

and i noticed you listed the CEL as a pro (as it does NOT turn on) which i assume is noted due to the CELs we've heard about with the new CS intake. it'd be fair to note that the CS intake CEL issue is handled quite effectively by the piece they have shipped to those that have experienced the CEL.

i'm just kind of coming up with these on the spot as i look at this part. it looks great and looks easy to install (per your other post which was quite detailed. great job on that!). btw...cost was not mentioned in this post. HOW MUCH IS IT?! :D

ps - if you happen to have a vid of it with the car running so we can hear it in action, that'd be stellar. :)
 
Yes Protephile (kargoboy@hotmail.com) is on this site as an authorized dealer but he frequents the other site more often.

I believe the new intake would still be too new to have good dyno numbers posted. But here is some information from their site:
http://www.simota.com/main.htm?pid=23&Focus_ID=38&Class_ID=38&Sub_Class_ID=48&Brand_ID=&Prod_ID=100

As well I am sure you could find some dynos from previous generation Mazda3s on the other sites. I have had experience with a but of different intakes and prefer the Short RAM style, unless you are sitting there idling there is plenty of air still coming through. Plus on our 2010s there is still part of the fresh air ducting bringing in air around our filter.

As for the filter changing I knew I would be asked this question, so I took some pics. It only requires the removal of 4 screws and a little twist and you will be good to replace it or clean it. See below:

I don't want to bash on anyones practices, but I like the fact that this one work right out of the box, with no problems.

Gary is working on a GROUP BUY, so you will be able to pick it up for a good price. Around the same or less than the other Intake options.

I'm Canadian so we get bad weather, so I will have sound clip eventually.
 
sorry, but I would not trust any intake that includes a "breather" that allows unmetered air in after the MAF sensor has done its job.
 
No, the intake itself. The stock air box has a baffle to quiet it down, an aftermarket intake doesn't have this, and there is increase air flow.
 
i knew that lol...but what purpose does the breather serve? anyone can answer this. i'm not saying it's bad...just not sure how that works better than the stock line from the intake.
 
This is the quote I have been given people, that asked the same question.

Quoting a random performance site:

Due to emission requirements many modern engines have to re-combust their own breather fumes, tending to result in a loss of power, due to coking up of the intakes, throttle bodies, inlet valves etc, and lowering the airflow into the engine. Breather filters such as this allow the venting out of these fumes.

Engines will always realize more power when they are not forced to reburn the hot waste gasses of previous combustion cycles. The more worn the engine the more fumes it will have, making matters worse. Even on a new competition engine there will be more fumes (than a road engine) vented from it due to the engine being built with larger clearances - to reduce friction and allow greater heat expansion.
 
sorry, but I would not trust any intake that includes a "breather" that allows unmetered air in after the MAF sensor has done its job.

I don't think it makes a lot of difference, as a lot of cars have run them in the past.

That breather doesn't allow any air into the engine's combustion process, it's a valvecover breather. It replaces the vacuum source that the factory intake uses to evacuate crankcase pressure. That being said, adding vacuum to the crankcase is a good thing because they're a critical component of the positive crankcase ventilation system. Change the vacuum values of the system and risk blowby on deceleration. Remove the inlet vacuum source and the PCV won't open on deceleration to prevent blowby.

On the other hand, there are benefits to avoiding bringing oil vapor into the intake tract, which is where catchcans come in handy. They get you the best of both worlds.

i'd rather Wingzero not be the one 'defending' this product or its accessories. it'd be nice of the vendor that is selling would add his thoughts to this post and answer questions. it's not really fair to Wingzero.
 
You shouldn't take what JeebusM3 as a grain of salt as it is only formulated opinion. Whereas Jason, knows what he is talking about and breaks down the positive and negative.

There's no real positive. You are trading trace amounts of oil that the car was engineered to deal with, for blow-by.

As Jason stated, ideally you would have a catch-can.

I've been a vendor on this site for years. Among many of the new products I've brought to the U.S., the Simota line is one of them. Their intakes have been very popular with the Mazda 3 crowd. I just don't get a lot of non-Protege support here but the Protege people are very familiar with me and my reputation.

That breather doesn't allow any air into the engine's combustion process, it's a valvecover breather. It replaces the vacuum source that the factory intake uses to evacuate crankcase pressure. That being said, adding vacuum to the crankcase is a good thing because they're a critical component of the positive crankcase ventilation system.

Thanks for insight. I was not aware that my test-fitter was going to post a review on this site. Good luck with you own intake design, it's very nice as always.

There's no real positive. You are trading trace amounts of oil that the car was engineered to deal with, for blow-by.

As Jason stated, ideally you would have a catch-can.

A catch-can is a nice addition, I agree. You can also run your own breather tube if you want. it's not difficult. This is the design that Simota has offered.

That said, I'm not going to allow this thread to turn into a bashfest.
 
without getting into any of the details, i wanted to say thanks for coming onto the board to post and show your presence. i think it's important that people get their say and freely express their opinion, but it's best to hold back until all the details are out on the table. plus i like to see as many options for our car as possible. it's a win win.

Not sure what you mean about the details...it was a test-fit and a review. The product will continue to evolve.
We all have problems with a first version at times, just ask Jason about their own intake.
As for showing my presence, lol, I've been showing up on this board and posting
every day for about five years, well before I was a vendor I was a Protege owner.
Your comments are welcome any time though. I don't stop any civilized discussion---just read all the posts about the V1 MSP Thunder manifold!
