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! Head over to the Subaru Accessport Map Database to view the full selection of SF Intake Maps for your vehicle.

Absolutely love it

The Cobb intake with box is amazing. Running the accessport with the intake and OTS tune does wonders. Sounds great, much better throttle response. I highly recommend this intake, just make sure to get a proper tune!

STI Mike,

Running the COBB SF Intake and Airbox package alone is a huge improvement, add in the COBB Accessport and the STI is a completely different car! Just as you said, the sound and throttle response is greatly improved! A pro tune is absolutely going to improve your experience even more! Thank you for your 5 Star Review!


Nicolas Dominguez
A Must!!!!!!

The sound is phenomenal, jaw dropped when I took her for a spin. This is a must for your subie, daily or track car. Just make sure you tune it once you install the he mod.


Thank you for the 5 Star Review! The COBB SF Intake and Airbox package is an easy install, and as you said is an absolute must! The OTS Maps from COBB work directly with this package or custom tuning, ensures you get the maximum from this intake! You will absolutely notice the difference!

Cobb intake

Great working order quick shipping !! Works Great for my 2015 Subaru STI


Thank you for the 5 Star Review! COBB designed the SF Intake and Airbox to provide optimal flow for performance while minimizing turbulence. The Air box helps provide the benefits of a cold air intake preventing hot engine bay air from getting into your intake system. All of this provides more HP and better performance.
