SUBARU EXPANSION TANK STI WRX 02-07 WRX & 04-16 STI POLISHED

Fabricated WRX & STi Expansion Tank.

Aeroflow Performance has constructed this durable, TIG-welded aluminium coolant expansion tank for perfect fitment in the 2002-2007 WRX and the 2004-2016 STi. Stock coolant expansion tanks are prone to failure after years of constant temperature variations, the plastic material becomes brittle. Our Fabricated tank features barbed fittings and a 50% increase in capacity compared to factory. The barb fittings are removable and can be replaced for AN style fittings which are sold separately.
