This is a C.A.R.B. certified (2010+) COBB Tuning SF Intake that replaces the restrictive stock intake system. This particular SF intake system was designed with 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, a CFD-designed velocity stack leads to a unique air flow straightener grid design to smooth the incoming air flow as it passes the mass air flow sensor for precise readings.
Please note that all aftermarket intakes on 08+ models require tuning regardless of manufacture. COBB Tuning has off the shelf maps for the Accessport that will allow you to install, flash, and go.
These intakes feature a composite intake body for optimal heat rejection. Integrated velocity stack with integrated airflow straighteners. Post MAF, you will find 4-ply steel reinforced silicone. And enjoy a more aggressive intake tone under acceleration.
