PWR Subaru Impreza Alloy Radiator Assembly – GDA/GDB (2001–2007)

Full-alloy radiator for the 2001–2007 Subaru Impreza GDA and GDB, designed for efficiency, durability and reliability on the road and in motorsport. It gives good heat control for turbocharged EJ engines, whether standard or fully built.

Built with PWR's motorsport cooling technology, it uses a high-density core that improves thermal efficiency considerably over OEM units, keeping temperatures stable and consistent in daily driving, racing or high-boost track use.

• Direct fit for GDA/GDB (2001–2007): mounts on the factory mounting points for easy installation.
• High-efficiency core: race-grade tube-and-fin construction maximises coolant flow and heat transfer.
• Lightweight full-alloy build: durable, corrosion-resistant alloy tanks and core reduce weight without compromising strength.
• Motorsport-grade cooling: suited to fast road use, track days, rally stages, time attack and high-boost turbo applications.
• Engine reliability: keeps coolant temperatures in the optimal range to protect EJ20 and EJ25 engines under heavy load.

The GDA/GDB chassis is a favourite among tuners and motorsport drivers. Whether the car is a daily-driven WRX, a tuned STI or a competition car, this radiator supports higher performance levels, better tuning stability and long-term reliability.

Every radiator is TIG-welded using premium materials for durability, efficiency and cooling capability.
