Cobb Tuning Stage 1 SF Power Package - 2015-2021 Subaru WRX

The Starting Point That's Already Fast

The Cobb Stage 1 Power Package for the 2015-2021 Subaru WRX is the cleanest entry point into serious Subaru performance — an Accessport V3 paired with a high-flow intake filter that, together, give the VA WRX's ECU everything it needs to start working properly. The OTS (Off-The-Shelf) tune unlocks power that the factory calibration leaves on the table, and the intake filter feeds the turbocharger with less restriction. No downpipe, no intercooler swap — just the gains that come from tuning and airflow, done right.

The Accessport V3: The Tune First, Hardware Second

Every Cobb Power Package centers on the Accessport V3 — the most widely used Subaru ECU tuning tool on the market. The included OTS (Off-The-Shelf) map for the VA WRX is calibrated specifically for the components in this package, meaning the Accessport isn't just monitoring your car — it's actively optimizing fuel delivery, ignition timing, and boost targets to match the hardware. The Accessport V3 mounts to the windshield or dash and displays live data as you drive, and it can be retransferred to another vehicle or returned to fully stock at any time.

Everything Validated Before It Leaves Austin

Cobb's approach to Power Packages is to validate every component combination on their own test vehicles before releasing an OTS map. That means when you buy a Cobb Stage 1 package, the tune isn't theoretical — it's been run on hardware identical to what's in the box. Installation is straightforward: the intake and hardware bolt into factory locations, the Accessport plugs into the OBD-II port, and the package map is loaded from the device menu. No wideband, no dyno visit, no tuner appointment required to get on the road with Stage 1 performance.
