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. By limiting bypass and turbulence, it helps the intercooler manage heat during daily driving and spirited runs.
