Cobb Tuning SF Intake + SF Airbox - WRX 02-07, STI 04-07 & Forester 04-08
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.
