Description

Mishimoto Subaru 08-14 WRX/ 05-09 Legacy GT Aluminum Coolant Expansion Tank - Black

Add some additional reliability and engine bay styling with the Mishimoto Subaru WRX 2008-2014 Aluminum Coolant Expansion Tank. Stock coolant expansion tanks are prone to failure after years of constant temperature variations. The Mishimoto tank is constructed from durable, TIG-welded aluminum with barbed fittings for optimal durability and longevity. This expansion tank provides a 22% increase in capacity compared to the stock unit. It features a polished or anodized black finish that will look great in your engine bay, and it matches the Mishimoto Subaru WRX/STI Performance Aluminum Radiator. The Mishimoto Coolant Expansion Tank is engineered for perfect fitment in the 2008-2014 WRX and also fits the 2005-2009 Subaru Legacy GT / Outback XT! As with all of our WRX performance parts, this expansion tank includes the Mishimoto Lifetime Warranty.

Additional Information

Engine coolant reservoir designed to store and regulate excess coolant for proper system operation. Durable construction resists heat and pressure, helping prevent leaks and maintain optimal temperature.
