Cobb Stage 1+ Power Package Blue 2004-2007 Subaru STI / 2006-2007 WRX / 2004-2006 Forester XT

The Cobb Stage 1+ Power Package in blue for the 2006-2007 Subaru WRX, 2004-2007 STI and 2004-2006 Forester XT bundles the Cobb Accessport V3 with the Cobb SF Blue Intake System. The SF intake replaces the factory airbox with a cone filter and aluminum tube, and the Accessport OTS map is calibrated for the SF intake’s specific airflow characteristics on EJ255 and EJ257 platforms.

SF Intake on the Late-GD EJ255 and EJ257

Stage 1+ with the SF intake takes the late-GD WRX and STI beyond what a drop-in filter alone achieves the cone filter and aluminum tube provide greater airflow improvement than a panel filter swap, and the Accessport OTS map is calibrated specifically for the SF intake’s airflow characteristics rather than being a stock-intake map with a filter change noted. The EJ255 and EJ257 respond to the combination with improved throttle response and more consistent boost delivery through the mid-range.

Calibration for SF Configuration and the Path Forward

The SF intake retains the MAF sensor in its factory location within the intake tube, maintaining accurate air mass measurement for correct fueling across all operating conditions. The blue coupler is a natural choice for GD STI builds where the color coordinates with the platform color identity. The SF intake installed at Stage 1+ carries forward directly into FMIC configurations in subsequent stages without replacement.

Why Choose Cobb Tuning

Cobb Tuning has been developing performance software and hardware for turbocharged enthusiast vehicles since 1999. Founded in Austin, Texas, Cobb built its reputation on the Accessport and expanded into a full catalog of hardware engineered to complement it. Every OTS map is developed in-house on real vehicles, and every hardware product is validated as part of a complete system not sourced and sold in isolation. That integrated approach is why Cobb produces consistent, reliable results across the builds we see every day.

The RallySport Take

Stage 1+ for the GD WRX and STI is the correct foundation for builds that will progress further. The calibration library for these platforms is mature and validated Cobb has been developing EJ255 and EJ257 maps since these cars were new, and the depth of that development shows in how well the OTS maps address the specific characteristics of each engine.
