Keep Cooling Airflow Moving Through the Radiator at Low Speed
At low speeds, factory radiator setups can lose airflow efficiency around the edges of the radiator core, letting engine temperatures creep up in traffic or during hard driving. The GrimmSpeed Radiator Shroud directs more of the fan's pulling power directly through the radiator core instead of around it, improving cooling consistency at low speed. It's a direct-fit shroud designed for the Legacy, Outback, BRZ, and FR-S platforms listed in the fitment table below.
Key Features
- Improves low-speed cooling airflow through the radiator core
- Directs fan airflow more efficiently instead of allowing recirculation
- Direct-fit design for supported chassis platforms
- Helps maintain more consistent engine operating temperatures
- Straightforward installation alongside the factory radiator and fan

FAQ
What is the GrimmSpeed 094029 radiator shroud?
It's a direct-fit radiator shroud that improves low-speed cooling airflow through the radiator core on the Legacy, Outback, BRZ, and FR-S platforms.
Which vehicles fit the GRM094029?
This shroud fits 2010 and newer Subaru Legacy and Outback, and 2013 and newer Subaru BRZ and Scion FR-S.
Does this shroud replace the factory fan?
No, it works alongside the factory fan and radiator to improve airflow efficiency rather than replacing fan components.
Will this help with overheating in traffic?
By directing more airflow through the radiator core at low speed, it can help maintain more consistent temperatures during slow driving or idling.
Is cutting or trimming required for installation?
The shroud is designed as a direct fit for the supported platforms without permanent modification.
Does this work with an aftermarket radiator?
Fitment is designed around the factory radiator dimensions on supported platforms; compatibility with aftermarket radiators may vary.
Will this fit a Toyota 86?
The Toyota 86 shares its platform with the BRZ and FR-S, so fitment is typically the same, though always confirm against the listed applications.
Is this shroud made of plastic or metal?
GrimmSpeed radiator shrouds are constructed to be durable and lightweight for effective long-term underhood use.
