Well I think you know the difference between need and want, at least I hope so.

You wanted the cool noise/look the intake gives you, as it does nothing for your car without a tune. The stock airbox is quite good, so there is no "need" to replace it. Maybe with a tune you will get couple HP more, but not worth the money.

General consensus on the forum is that if you install an aftermarket intake, you should get a tune right after that. I'd read this:

If it were me, I wouldn't just take a manufacture's word that it's safe. Especially since the 2015 is so new and the tuning for it is still getting developed.

It's your car and I'm a random dude on the interwebs. Hope it works out...

I do know the difference, thanks. I also know the manufacture claims acceptable A/F ratios on the stock tune. That's also why I stated, if you install this product, you're doing this at your own risk! Need I say again, AT YOUR OWN RISK. Don't be the fat person who sues MacDonalds because daily, you ate large sized quarter-pounder meals with a diet Coke and have a heart attack at 45. I actually had a heart attack at 36, but I'm 5'11" and maybe 170. Family history sucks. This also may have skewed my vision of acceptable consequences but I know, I have to pay for my actions. I'm not going to blame you if I blow my car up. I'll be the first person to call myself an idiot. Once, just once.

That being said, here's another short video. Windows up and you can hear the woosh better near the end of the video. Flyby's hopefully in the next couple hours. Then, I'm staying out of boost as much as possible, for a while or until tuned.

Enjoy and be safe! So far, I'm lovin' it.

OP: Great review! Thanks for posting your feedback, images, and video. We are very pleased to see that these units are being installed already!

Correct! We have confirmed that this intake will function perfectly on the stock tune with 93 octane fuel. We saw great power gains with safe AFR's on this fuel type. 91 octane users will need a tune. We are finalizing our tunes and should have them available for EcuTek users very soon.

It is possible that a dealership will question your intake installation if a warranty concern were to arise. This will vary from one dealership to another.

We have performed extensive testing to verify that this intake provides improved power in a safe manner. During testing, we monitored vital sensor readings, including AFR's and Knock, to be sure we were developing a safe and effective product. This intake kit provides both power and improved engine noise.

Check out more details regarding our testing results in the thread below.

Feel free to shoot us a PM with any specific questions!

Thanks again OP!

This might be dumb, but what about 92 octane? Obviously, the higher the octane level, the lower your chances are for knock.

Thanks!!

Uploading flyby now. Done on a back road, safely and below the posted speed limit. Yeah, I think it's faster or I'm disillusion or very possibly, D, all the above! You be the judge...

Watch on surround sound with sub-woofer for full enjoyment.

Well if it's a 2008+ then you risk blowing up. I don't understand why people try and "what if" when it comes to crap, do you have a spare motor or the cash for one to "try" and play what if?

To each their own I guess. Just be smart and try to be easy on the car if you do this install prior to a tune.

Found the results but they are not labeled too well. There really needs to be more information on the conditions each dyno was performed with, otherwise they are not very useful. One tests indicate the vehicle was driven "some" the others do not even say this. These tests should not be compared/used unless they are run under identical conditions and prep, with the ONLY thing being different is the part/exhaust/gas etc. Temp? Was any of the gas 10% ethanol? How much driving behind each car/ecu learning happened? I could go on. There are just too many variables being changed or unknown, making the results worthless imo. I'll give you that it does help performance.


Can Mishimoto explain the how this works for 2015 models and not others?

Did I read correct that if you have the intake + custom exhaust a tune is needed due to lean AFRs on 91 octane gas?

Many states/areas do not have 93 octane gas... 92/91 is also very common.

Hey man, thanks again for the write up, got my intake in the mail today, installed it, referenced your pictures a couple times. I took out a hell of a lot more clips and screws bolts etc than you did haha, I'm not sure how you did it taking off so few. Took a little over 2 hours but it's in there.. Took a short ride, didn't get over 4k rpms on the trip, sounds great though. Could have been placebo effect but the car didn't seem to have the common "jittery" throttle issue.. Idk though, Probably only drove 15 miles and I was pretty gentle.. Did you notice anything similar?

Throttle definitely feels more responsive, no doubt. Sorry, maybe I just got lucky with the 5 clips I pulled. I spent a fair amount of time looking from the top when I was removing the stock intake before I went under.

I know it wasn't the best write up in the world but I'm glad it helped some. I'm guessing this wasn't your first time under a car either? Like I said, I love this thing so far! About 100 miles on the odometer since installed.

I think we're trying to give the ECU a chance to learn and adjust slowly under lighter loads. I also plan on a tune in the next few months. Plus, it's not smart, at least in my experience, to hammer on any car with a new major engine component installed, right from the start.

With respect to the OP's installation as an example, how is this a CAI when there is no segregation of the filter from the engine compartment?

Without segregation, the filter will be pulling hot under-the-hood air into the intake.

Well stated! Maybe they should change the name to "performance intake".

I wish I had numbers to prove it but I can't see how an open filter, with the scoop feeding it, wouldn't allow for more, cooler air, into the intake. If that makes sense. I'm traveling and I hate typing on this stupid tablet.

Well its not pretty or shiny or anything, but here is mine installed w/box... 2nd drive this morning, on the way to work, I swear this significantly helps the common jittery issue that '15 WRX owners experience........ Cannot comment on performance... Sounds great though

How long of an adjustment period would you suggest? Asking since I am new to this and getting my intake on Monday. Thanks

I'm not the manufacturer but I would say, the longer you can ease into it, the better. I'm doing my best to wait 500 miles but I drive at least 250 miles a week. Again, I'm going to stay out of boost, as much as possible prior to a tune.

Are you going for a professional tune or getting your own ecutek device with mishimoto CAI specific roms? I am thinking of the second route. BTW I drive 160 miles per day

Waiting for a Dyno and the Cobb. Good, you'll break it in soon! Best of luck!

Have any I you guys with the 2015 WRX cvt had any issues with you ECU? I've been reading in a lot of places that the ECU is having problems and it makes you CEL come on? Any information would be great... I'm looking at getting one in the next couple of days, but now I'm hesitant!

800 + miles and no issues. I've generally been easy on the throttle but I'm also trying to introduce boost regularly. I would plan on a tune if you get one to avoid any issues. I haven't had the time.
