Add some additional reliability and engine bay styling with the Mishimoto Subaru WRX 2002–2007 / STI 2004–2014 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 50% increase in capacity compared to the stock unit. It features a polished silver 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 2002–2007 WRX and the 2004–2014 STI! As with all our products, this expansion tank includes the Mishimoto Lifetime Warranty

Nice looking coolant expansion tank!

Great quality! Looks nice! It was a little hard to fit but it was because of the intercooler pipe and the Cosworth Intake Manifold.
