Matched Aluminum Radiator Shroud and Alternator Cover Package

The Cobb Aluminum Radiator Shroud replaces the factory plastic radiator shroud that directs airflow through the radiator core. The factory plastic shroud degrades over time from sustained heat cycling — it can crack, warp, and lose its sealing contact with the radiator core edges, reducing the efficiency of airflow direction through the radiator. The Cobb aluminum replacement maintains its shape and sealing contact indefinitely, providing consistent radiator airflow management throughout its service life.

Consistent Finish and Factory Location Installation

The radiator shroud and alternator cover are two of the most visible components in the Subaru engine bay. Purchasing both together ensures a consistent black finish across the most prominent aluminum dress components. Both install at factory locations without modification.

Why Choose Cobb Tuning

Cobb Tuning has been developing performance software and hardware for turbocharged enthusiast vehicles since 1999. Founded in Austin, Texas, Cobb built its reputation on the Accessport and expanded into a full catalog of hardware engineered to complement it. Every OTS map is developed in-house on real vehicles, and every hardware product is validated as part of a complete system — not sourced and sold in isolation. That integrated approach is why Cobb produces consistent, reliable results across the builds we see every day.
