PERRIN 02-07 Subaru WRX/STi Radiator Shroud - Neon Yellow

This is the PERRIN Performance Radiator Shroud. This shroud has been designed to improve the overall cooling efficiency by channeling the incoming airflow to make direct contact with the face of the radiator. Typically under driving conditions, the air would hit the face of the radiator and then get deflected in all other directions. The shroud prevents the air from getting deflected into the engine bay forcing more air to stay in contact with the radiator. 

Additionally, other benefits include improved engine bay aesthetics, along with a place to put your tools while performing maintenance.
