Grimmspeed V2 Cast Aluminum Turbo Inlet 2015-2021 WRX / 2014-2018 Forester XT

One of the most common complaints from 2015–2021 WRX owners is cracks forming in the OEM plastic turbo inlets. Over time, the plastic becomes brittle and can separate around the BPV or turbo flange, risking inconsistent airflow and potentially harmful engine conditions. The GrimmSpeed Aluminum Turbo Inlet solves this problem by providing a durable, cast aluminum replacement that eliminates cracking and ensures reliable, consistent airflow.

Development & Flow

GrimmSpeed used precision laser scanning and Faro Arm measurements to design a perfectly fitting inlet. Multiple 3D-printed prototypes were tested to optimize real-world fitment and airflow, eliminating the air pockets found in OEM inlets. While the inlet alone won’t provide massive horsepower gains, it is an essential upgrade for a high-flow intake tract, ensuring safe and unrestricted airflow to your engine.
