The factory coolant tank in the RX-8 is known to fail after repeated high-heat situations. The neck may become deformed, or the tank may separate completely. This replacement tank by Moroso is constructed from high quality aluminum and features a billet aluminum radiator neck that accepts OEM small radiator caps. This coolant expansion tank is a direct bolt-in replacement for the flimsy stock plastic tank. The superior craftsmanship and quality materials guarantee that this product outperforms the OEM piece in every single way.
