The C.A.R.B certified COBB Tuning SF Intake removes a pre-turbo restriction in the stock intake system. The SF Intake intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. From a custom conical cloth air-filter element, a CFD-designed velocity stack leads to an unique air flow straightener grid designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The intake utilizes a one piece design constructed from a high temperature plastic composite, saving weight and reducing heat transfer.
Increased Induction Sound
Enjoy the increased snarl from your engine and hear the turbo spool more clearly with the addition of the COBB Tuning SF Intake system. Turbocharger induction noise and bypass valve venting sound is much more audible using this intake system.
Easy to Install
The COBB Tuning SF Intake was designed to be easy to install without having to modify your car. Installation requires no cutting or trimming of any components and can be completed with simple hand tools. Simply remove the stock airbox and bolt the SF intake into place in just minutes. The filter comes Pre-Oiled ready to install.

Awesome Product - 2015 STIPrior to installing the intake the car was 100% stock. Installation is super easy (30 mins) and requires only the simplest of tools. After installation I downloaded the 15 STI 91+map from the website and uploaded it to the car. I highly recommend this combo to anyone feeling like the car deserves a bit more power. I was surprised to find the car pulls noticeably harder and sounds amazing. The intake is loud so if you don't want to hear the turbo/wastegate keep the stock intake and just flash to stage 1. I went 91 tune although I run 93 octane to stay on the slightly safer side. Great products!

Best Intake Around, Great Fitment & Performance, Awesome Sound.Installed on my 2015 WRX STI, Install of any intake is really simple but Cobb's instructions were very easy to follow. The stock MAF sensor, bracket, nuts/bolts fit flawlessly and all air connections are definitely air tight. Installed in about 30 minutes, tuned the car with the available OTS map on Cobb's website (93 Oct , SF, Normal Wastegate), and off to the races! Thing sounds like a jet plane when you barely even hit boost, the sound of the wastegate is much more prominent as most could figure. As for power gains there is a noticeable difference but I haven't compared my data yet to check. To anyone else that has a 2015, This does remove the stock intake tube that goes into the cabin and you don't have to do anything after its removed. I'm not a fan of CAI due to the pain of getting to the filter so Cobb's SF intake is a dream come true, Thanks Cobb!!!

Great sound, DEFINITELY requires tuning!!Installed this intake within about 20 minutes, super easy! Need just an 8mm, 10mm sockets & ratchet, and philips screwdriver. Looks clean. It's C.A.R.B. legal, which is great for me in CA. Like it states in the product info-NEEDS TUNING!! Just ordered the Accessport to compliment this. Car hesitates WOT near 5,000rpm, but Cobb states you need a tune! All in all, 5 stars and worth the price/legality/cleanliness!! Going to perform a ECU relearn, which might take care of it. But still want the AP for all the other features.

Awesome sound!I recieved my sf intake today for my 2015 STI. Install was easy, even though I had to remove the factory sound tube. I just put a rubber stopper where the tube used to be. Looks great in the engine bay. Turbo really spools up and it sounds like I have an aftermarket BOV. Throttle response was touchy at first, but this could be due to my car relearning the stage 1+ map. Overall great product! Can't wait for the airbox and stage 2 maps to come out.

Good intake, but..I have been using this short ram intake I with a custom AP tune for a while and it runs beautifully. However in order to run most front mount intercooler's, you have to trim the silicone coupler and move the intake back a bit, in order for the Piping to fit.
And in doing that, you can no longer use the metal bracket that comes with it, but it stays pretty well without it anyways, so no worries there.
Only reason i gave it 4 stars instead of 5. Is because it is not compatible with a front mount intercooler. However, with
little bit of trimming the silicone coupler moves the intake back it will fit with no problems.

Horrible Customer ServiceI made the mistake on buying the STI intake for my WRX. I realized after it already had been shipped. I requested a refund and they told me to send back. The day I got the intake, I did not unbox, I just sent it right back in the same box they sent it in. After a few days, I asked them if they had received it and they advised that there were no updates.I haven't heard from them since. I emailed twice to inquire about my refund since I sent their item back and they have yet to respond. Its been over two weeks now and I am out 195,00 after I sent their item back. I am sure there performance parts are good but I've had horrible luck with their customer service so far.

Great intake if you aren't afraid of some noiseI've had the AEM, modified stock box and now the Cobb sf. The Cobb is by far my favorite. My A/F learning has stayed below 3% since install. I am always surprised by the quality of the packaging when making a purchase from cobb. I'm currently on the OTS cobb stage 2 sf intake map. Catless turbo back. The turbo spool is insane. I personally love hearing all the noise my engine makes. This is not a quiet intake by any means. I will be using the airbox during the summer to avoid ambient engine heat but am currently running it without one. Never above 98°f intake temp at 6600ft. My stock box would get upwards of 134°f!

Great Producti owned a 2012 wrx sti limited, first of all the product looks amzing, and how it was made, its worth every penny, installation took 10min, installation is very easy, i didnt even have to search for an instruction, thats how easy it was. After the install, i installed the appropriate map, which for mine is stage1+SF, i was amazed how i can hear the turbo spool now and the stock BOV, is very noticeable. overall i highly recommend this product whos looking to do a first uprgrade, and dont forget the cobb AP.:)
