IAG Coolant Expansion Tank for Subaru WRX/STI

Elevate your Subaru WRX or STI's engine bay with the IAG Coolant Expansion Tank, a high-performance upgrade designed for enthusiasts seeking a race-like setup. This custom aluminum tank is crafted to optimize space and enhance your vehicle's cooling system, making it an essential component for those looking to install a rotated turbo kit.

Custom Aluminum Construction and Features

The IAG Coolant Expansion Tank is made from 1/8" thick sheet aluminum, ensuring durability and reliability. This robust design is complemented by a range of features that cater to both form and function. Notable among these are the -6AN coolant turbo return fitting and the -8AN drain outlet fitting, which provide seamless integration with your vehicle's cooling system. The tank also includes a .25" barb fitting for overflow, ensuring a secure and efficient coolant management setup. The tank is finished with a powder coat in black, featuring the IAG logo, for a sleek and professional appearance. All necessary hardware is included for easy installation.

Optimized Engine Bay Layout and Compatibility

This IAG Coolant Expansion Tank is designed to relocate your stock overflow tank to the passenger side front strut tower, creating additional space for your rotated turbo kit piping. This innovative design not only maximizes engine bay space but also improves overall cooling efficiency. However, please note that this tank is not compatible with OEM hoses or the Cobb Airbox. This product is perfect for drivers who prioritize performance and aesthetics, seeking a custom solution for their Subaru WRX or STI.
