The Stage 1 Air Intake Power Package pairs the ECUtek Phone Flash system with Teter Auto’s upgraded air intake, designed specifically for the 2015–2021 Subaru WRX.
Teter Auto Air Intake System
This intake setup is an ideal starting point for WRX owners looking to improve airflow and engine response. The airbox is made from durable black powder-coated aluminum and is designed to draw in air from the factory scoop. A large, pre-oiled filter handles filtration duties, with airflow guided through a velocity stack-style MAF housing. Reinforced silicone couplers and quality clamps ensure a secure, leak-free connection.
Engineered for Flow and Accuracy
To maintain smooth, consistent airflow and precise MAF readings, the system uses a CFD-designed velocity stack, a high-flow conical filter, and an integrated air straightener grid. These elements reduce turbulence and ensure clean sensor readings. The MAF housing is made from lightweight, heat-resistant composite to help manage under-hood temperatures.
Tuning Capability
This package comes with a custom E tune from Cstuned, delivered through ECUtek Phone Flash. This is not an off-the-shelf map, but a fully personalized calibration created specifically for your vehicle, modifications, and fuel type. It ensures optimal performance, drivability, and reliability based on your unique setup.
For enthusiasts seeking even more refinement or peak output, an optional dyno tuning upgrade is also available.
WHY?
The Teter Auto Stage 1 Power Package is a straightforward bolt-on upgrade combined with expert ECUtek tuning to unlock the full potential of your 2015 WRX. Unlike generic off-the-shelf maps, this package provides a custom tune tailored specifically for your vehicle, ensuring both performance and reliability. Plus, there’s no need to connect any device to a computer — you can data log, adjust, and flash your tune directly through your smartphone, making tuning easier and safer than ever. Along with improved airflow from the Intake & Airbox setup, this package delivers serious power gains and a confident driving experience.
