Moroso Aluminum Coolant Expansion Tank WRX / STI 02-07 / Forester XT 04-08 (63784)

New from Moroso is this direct bolt-in replacement coolant expansion tank. It has 50% more capacity than the OEM tank. Fabricated aluminum was used for strength as factory tanks fail after repeated high-heat situations. This aluminum tank can be polished, chromed, painted, powder coated or left as-is for a race look. Includes billet aluminum filler neck, Moroso Racing Radiator Cap in the stock pressure range and integral billet aluminum hose fittings that are better looking and more trouble free than screw in fittings.
