Overflow & Expansion Tanks

Maintain optimal coolant levels and prevent overheating in your Toyota Supra, GR86, or Subaru BRZ with high-quality overflow or expansion tanks from FTSpeed. These tanks are designed to collect excess coolant and provide a reservoir for expansion and contraction of the coolant as it heats up and cools down. FTSpeed offers a selection of overflow/expansion tanks that are specifically designed to fit and function seamlessly in your vehicle's cooling system. We recommend reputable manufacturers like Mishimoto, Cusco, and Moroso for their reliable and durable tanks. Upgrading to a performance overflow/expansion tank can improve cooling system efficiency, reduce the risk of coolant leaks, and enhance overall cooling performance. Keep your engine running cool with FTSpeed's overflow/expansion tanks.
