California Residents: Prop 65 Warning


This C.A.R.B. approved 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. This COBB SF Intake does not require additional tuning once installed. It is designed to work perfectly with the stock MAF sensor. The filter even comes Pre-Oiled. Simply install and go!

Subaru SF Intake + SF Airbox is rated 4.7 out of 5 by 47.
Rated 5 out of 5 by from Great Sound & Quality Product! I installed the SF Intake on my 03 WRX Wagon in less than an hour without having to jack up the car or removing the wheel. The removal of the silencer was the most difficult aspect, but all in all it was strait forward and easy. Prior to installing the Intake, I was looking into purchasing a BOV for more turbo sound that some appreciate, but now Im glad I didn't. Unless you're pushing a lot of pressure it's not necessary, the sound from removing the air box/silencer was exactly what I was looking for. Now as far as power gains, I honestly didn't notice much but it did however make a little difference in throttle response. Quality product, definitely recommend this intake.

Rated 5 out of 5 by from Wonderful little kit. Product fitment is top notch, and the intake system feels very high quality. The air-box gives a nice clean look underneath the hood, and the SRI allows your turbo to be more vocal both inside and outside of the cabin. I didn't purchase this product anticipating huge power gains, but I will say that with the AP stage 1 tune, it feels a bit smoother than stock and a little more powerful in the top end. Highly recommended to those who want to hear the noise of the turbo rather than their stereo. Cheers!

Rated 2 out of 5 by from Forester XT Poor Fitment. I'd stay with the factory airbox. I'd rather see someone stick with the factory airbox than this piece. It sounds great, but functionally doesn't work as well as the factory airbox would. It leaves huge gaps that don't even come close to keeping unwanted heat out of the intake.

Rated 5 out of 5 by from Started bad, but ended amazing I ordered the intake, and installed it, and was putting my MAF sensor in, and noticed that the intake tube was the wrong one! I was pretty upset, but called COBB and talked on the phone with them and they had a new tube sent out within minutes Excellent customer support, super friendly. While very upset about all this, im glad i ordered from COBB. I would order it again, and receive the wrong part again, and be ok that with COBB ill be taken care of

Rated 5 out of 5 by from Cobb Intake + Blue hose I've had this product for over a month now and I can feel that the throttle response is way quicker. The sound of the intake turn heads everywhere haha, keep in mind that I will buy the blow off valve as well soon. I recommend you guys to buy the the blue hose, it makes the car look sick in the inside.

Rated 5 out of 5 by from Nice Intake Bought for a 2003 WRX Wagon. Perfect fit. Only modification was having to trim the boost solenoid cover. Left my silencer in place to aid air getting to the box, no trimming required on the silencer. When boost hits you can really here the whoosh from this intake. Overall it's a nice upgrade over the factory box. Install is fairly easy and took me about 30 minutes. The directions supplied are ok but if you know cars you can figure out the shortcuts and save some time. Example: flexing hoses/lines as opposed to removing them. No tuning required either. It's optional.

Rated 5 out of 5 by from Great Product I've had this on my car now for over a year. Excellent fit. Gives the car a nice sound inside and outside. With Stage 1 on AP works great.
