Made to fit 2015–2021 Subaru WRX and STI models, the IAG Radiator Shroud improves airflow across the radiator, boosting cooling efficiency and helping reduce engine temps. It’s compatible with both stock and aftermarket radiators and works with the factory intake snorkel for a precise fit. Built from lightweight aluminum with a streamlined one-piece design, it brings both function and a clean, finished appearance to your engine bay.
The IAG Radiator Shroud is engineered for a high-strength, lightweight upgrade over the factory plastic cover. Constructed from premium-grade 5052 aluminum, this durable shroud is laser-cut and precision-formed at our Westminster, Maryland facility. Unlike the OEM plastic shroud that can warp, crack, or degrade under high engine temperatures, this aluminum design offers long-lasting performance while enhancing cooling efficiency and under-hood aesthetics.
The IAG Radiator Shroud is easy to install. The shroud is designed to fasten under the Subaru factory radiator stays or the IAG Radiator Stays using the original hardware. The entire installation process can be done in under 35 minutes using basic hand tools.
