Clean Engine Bay, Directed Airflow — The GrimmSpeed Radiator Shroud for the VA WRX/STI
The GrimmSpeed Radiator Shroud in Red for the 2015-2021 Subaru WRX/STI covers the exposed area above the radiator core with a finished panel that improves engine bay aesthetics and helps direct airflow through the radiator core rather than around it. The red powdercoated finish coordinates with other GrimmSpeed engine bay hardware.
Directed Airflow and Engine Bay Presentation — Two Problems, One Part
The stock Subaru VA WRX/STI engine bay has an open gap above the radiator that allows intake air to bypass the radiator core rather than passing through it — reducing cooling efficiency at low speeds when ram air pressure is not forcing air through the core. The GrimmSpeed shroud covers this gap and directs incoming air through the radiator for improved low-speed cooling performance. The finished panel surface also eliminates the raw, unfinished appearance of the open engine bay in this area.
Bolt-In at Factory Mounting Points — No Modification Required
The GrimmSpeed radiator shroud bolts directly to the factory mounting points in the VA WRX/STI engine bay. No drilling, no modification to the radiator or surrounding components. The powdercoated finish resists chipping and fading.

Straight From Subispeed
The GrimmSpeed radiator shroud is the correct engine bay finishing piece for the VA WRX/STI — it addresses both the functional gap in cooling airflow and the visual gap in engine bay presentation with one part. The red finish coordinates naturally with other GrimmSpeed hardware if you’re building out a matching engine bay aesthetic.

About GrimmSpeed
GrimmSpeed is a Pacific Northwest-based performance parts manufacturer that has been building Subaru-specific hardware since 2003. Founded by engineers who were actively building and racing Subarus themselves, GrimmSpeed’s catalog reflects the priorities of people who use the products they make — turbo inlets, downpipes, uppipes, boost controllers, intercoolers, and engine bay accessories designed specifically for the EJ and FA-series Subaru platforms. Every GrimmSpeed product is engineered, tested, and refined in-house, and their focus on Subaru means the fitment and function reflect a deep understanding of the specific platforms they cover. Subispeed carries the full GrimmSpeed catalog because their approach to product development consistently produces parts that perform as advertised and fit correctly out of the box.
