The 2015 Subaru STI SF Airbox and Intake/Airbox Combo are now available from COBB Tuning!

2015 STI SF Airbox

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 Airbox, which encloses the SF Intake. Hot engine bay air that robs horsepower is prevented from entering the intake system to provide consistent intake performance. 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.

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.

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.

  1. Hey Marshall,
    You mentioned before that with the stock fuel system, adding both exhaust and intake is not a good idea. I’m looking to buy the SF now that the airbox came out. I have the SPT “performance” exhaust on mi STI. Does that generate a problem? or do the problems only come if a change the downpipe or go for an aftermarket exhaust?

    Thanks,

    Joe.

    • Hey Joe, you should be just fine with that setup. In general, changing the catback exhaust does not require any calibration changes. You would still be able to use our Stage1+SF OTS map without any issues!
