Subaru STI Intercooler Ducting - GrimmSpeed - 02-03. A focused splitter that channels fresh air from your STI-style hood scoop directly across the top-mount intercooler for consistent, repeatable performance.

Built for 2002-2003 Subaru platforms running an STI hood scoop, this ducting improves the seal to the intercooler and directs airflow where it’s most effective.
