GrimmSpeed 15-21 Subaru WRX Version 2 Aluminum Turbo Inlet

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. The Version 2 differs from the original by combining the 2015-16 and 2017-21 fitments into one kit with interchangeable threaded fittings to perfectly fit the PCV return line on either the earlier or later models.
