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. Simply install and go!

Subaru SF Intake + SF Airbox is rated 4.7368 out of 5 by 19.
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 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.

Rated 5 out of 5 by from Great Performance improvement I bought the airbox primarily for the improved sound but I was surprised by the performance increase especially the low end throttle response. The sound however is more subtle than I expected but I really like it. I left my stock silencer in so that may be why. Great upgrade I wish I had done earlier.

Rated 5 out of 5 by from sounds great (much better than i thought) just put this in my 07 wrx tonight. took it out for a spin and it sounded amazing. really opens up the noise of the turbo and gives you a nice blowoff. as far as installing this goes it took me about an hour and a half all together. This product is well worth the money, if you're going to upgrade parts you might as well go with the best.

Rated 4 out of 5 by from SF Intake I bought the sf intake lot for my 2003 wrx sedan, as well as the Subaru Post MAF hose. It's only been installed on my car for a few days and I have already thrown a check engine light. When I had it checked it out, it's saying I'm running to lean in bank 1. Any suggestions?

Rated 5 out of 5 by from Overall very happy I've previously owned just the SF intake and loved it so much, so for my newer wrx I decided to get the intake AND airbox. The whole thing works great and I'm really glad I bought it, COBB is an incredible company. The SF intake hooks right up easy and sounds AMAZING!! ...That being said, I have to list the not so good :) Obviously these things aren't cheap and I was kind of disappointed with installation of the airbox. To me, for such a simple functioning item it was way more time consuming than it should have been. just my opinion. trimming the gasket was pretty annoying and its pretty tough to get all of the holes to line up perfectly. Overall I love it but the reason I bought the airbox kit was because i thought it would be a simple package that just went right in. In retrospect I feel I could have bought sheet metal and made almost the same thing (yes, yes i know it wouldn't have looked nearly as good! just saying...). I dread the day i have to take the 4 bolts out to get to the filter, they were so difficult to get in because I couldn't get the holes to line up. tiny screws, just kind of asking for stripped threads. My recommendation or desire would be for COBB to look at a possible way to either have the box assembled as one piece or maybe made out of a blow molded plastic or something? Just my opinion! But again, LOVE the end result and function/performance, I really do recommend it, especially even just the SF intake. The sound is incredible and it looks awesome! Thanks COBB!
