COBB Tuning Stage 1+ Power Package Black – 2008-2014 Subaru WRX/STI / 2009-2013 Forester XT

Cobb Stage 1+ Power Package — Black — 2008-2014 Subaru WRX / STI / 2009-2013 Forester XT

The Cobb Stage 1+ Power Package in black for the 2008-2014 Subaru WRX, 2008-2021 STI, and 2009-2013 Forester XT bundles the Cobb Accessport V3 with the Cobb SF Black Intake System. The Accessport provides OTS calibration independently developed for EJ255 and EJ257 platforms with the SF intake, and the black SF intake replaces the factory airbox with a cone filter and aluminum tube.

GR-Generation EJ255 and EJ257: Mature Calibration on Proven Platforms

The GR-generation WRX EJ255 and STI EJ257 are among Cobb’s most established and thoroughly developed tuning platforms. The OTS map library for these engines reflects years of real-world testing — calibrations that address the specific knock thresholds, fueling characteristics, and boost response of the EJ255 and EJ257 precisely. Stage 1+ with the SF intake on these platforms produces improvement that GR owners consistently describe as transformative for the investment: sharper throttle response from off-throttle, more confident boost delivery, and a more aggressive character from engines that were already considered among the best turbocharged Subaru applications. The FMIC OTS map variants for intercooler-equipped builds are a key inclusion — for GR STI owners already running a front mount intercooler, the Stage 1+ calibration accounts for the colder charge air temperatures the FMIC provides and targets more aggressive ignition timing accordingly.

SF Intake, FMIC Map Variants, and Broad Coverage

The 2008-2014 WRX EJ255 and 2008-2021 STI EJ257 are both covered by this single package — one of the broadest-coverage Stage 1+ bundles in the Cobb catalog. The Forester XT EJ255 is fully supported with its own platform-specific maps that account for the Forester’s different cooling capacity and weight distribution. The black coupler provides a clean, understated appearance that suits owners who prefer the intake to blend into the engine bay rather than stand out. The Accessport gauge display gives GR-era Subaru owners real-time data the factory instrument cluster never provided — boost, wideband AFR, IAT, and coolant temperature in the driver’s sightline.

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+ on the GR WRX and STI is the standard starting point for builds that will progress further — the SF intake carries forward to FMIC and Stage 2 configurations, and the Accessport handles calibration throughout. For GR owners who want their EJ255 or EJ257 running as well as it can, this is the correct first step.
