The C.A.R.B. Certified 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 Airbox, 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 intake airbox is constructed of 16 gauge aluminum, consisting of a one piece surround, directional lid, stainless steel hardware and all the necessary components for a seamless install with OEM quality fit and finish.

Subaru SF Airbox is rated 3.8 out of 5 by 10.
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 Love cobb!! I bought this and it was delivered on time like always, great quality products, and great fitment. I even got an extra license plate cover (which I planned on buying later anyway, glad I didnt). Cobb has had excellent service every time. Can't wait to do more business with them

Rated 4 out of 5 by from Fits the 2007 WRX perfectly I purchased this item about a month after buying the SF intake. I really like the way it looks under the hood, and the peace-of-mind it gives me knowing it's preventing the heated air from the engine from being sucked in.

Rated 5 out of 5 by from Keep you IAT under control! This is an absolute must for anyone with a Cobb SF intake. I saw a drop of around 30 to 40 degree iat’s. Car runs so much better in the heat and even better in the cooler night temps. MUST HAVE!!!!!

Rated 3 out of 5 by from Sounds great but doesnt quite fit -03 wrx It doesnt quite fit because the cone is jammed up against the fender due to hole in the air box and maf sensor positioning

Rated 4 out of 5 by from Sf airbox Thought it would keep temps down much better but only noticed a 10 degree difference. Still very happy with the purchase.
