Description

This intake and integrated airbox looks great and has the combined benefits of a short ram intake and a cold air intake without any of the negatives. This 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, we use a CFD-designed velocity stack leading to an unique air flow straightener grid. This straightener grid is specifically designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. This eliminates the "dead spots" experienced by other aftermarket intakes due to turbulence. No other aftermarket Subaru intake system utilizes these critical design elements. In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, we utilize a one piece design constructed from a high temperature plastic composite. Not only does this save weight compared to the previous metal design, the plastic composite material offers much better heat rejection properties that help keep intake air temperatures cooler. In contrast, intake systems constructed using metal castings or piping can actually retain underhood heat and in turn heat the incoming air. The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory inlet directs cold air from the front grill to the SF Air, which encloses the SF intake. Hot engine bay air that robs horsepower is prevented from entering the intake system. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes. Calibrations - All aftermarket intakes for 08+ Subarus require tuning in order to ensure the MAF sensor reads properly and the engine operates within safe parameters. COBB Tuning has you covered with Off-The-Shelf Maps for the Accessport, making it as easy as install, flash and go!

Reviews
Subaru SF Intake + Airbox STI 2015-2018 is rated 4.8 out of 5 by 43.
Rated 5 out of 5 by from Easy Installation, huge gains in power for the money! I purchased this product 2 weeks ago and I'm very happy with the ease of installation and gains in power. Pros: The "airbox" (or perhaps more accurately described as a complex hot air shield) is a well designed solution for a common issue (heatsoak). It prevents sucking in all the engine bay hot air by providing a less restrictive path (intake snorkle's path), of course, this only works once you start moving. Power gains over an AP map-only are immediately noticeable, as is the intake noise! I love it. Cons: I wish the instructions were more detailed, I watched a youtube video that clarified a few things, but where to apply the gasketing on the 'airbox' was not clear, nor was the usage of the screws and washers. More pictures would have helped, or even directing me to a detailed YouTube video.

Rated 5 out of 5 by from Awesome Product - 2015 STI Prior 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!

Rated 5 out of 5 by from 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!!! Check out the photos to see the difference between stock and aftermarket.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Great Product i 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.:)

Rated 5 out of 5 by from Excellent Quality I purchased the AEM intake a few years ago for my 11 WRX and decided to replace it this year vs. continuing to purchase the replacement AEM filters. The Cobb intake is something I should have purchased a while ago. Not bashing AEM as it's a decent product but the quality of the Cobb intake is much better, washable filter is a bonus, size is more manageable and the rally box is an awesome option.

Rated 5 out of 5 by from Impressed So I bought this Setup from Rally Sport Direct and paid for the next day air. I was excited when the SF intake/airbox arrived. Opened it up only the find it was missing the Silicone hose. Happy to bummed in 1.2 sec. I contacted Cobb and explained what happened. They told me what I needed to send them and with in 1 hour of sending the email I received a phone call from a Cobb support tech. Said they were very sorry for the inconvenience and would ship out the Silicone hose out ASAP. Now this all happened on Friday so I'm thinking I will have it Monday boy was I wrong it showed up on Saturday and had a lil bonus Cobb T-shirt. I understand accident's can happen when you order from online but the True customer service from Cobb is well above the standard. Just wanted to say thank you and the SF intake & SF box look/sound Amazing.
