Add some additional reliability and engine bay styling with the Mishimoto S650 Mustang wrinkle black expansion tank.

Prevent starvation. The Mishimoto Mustang expansion tank has internal baffles to prevent coolant starvation from overflow ports to engine. Also, during high-speed cornering, braking, and acceleration, the internal baffled reduce coolant sloshing.

Practical upgrade. The engineers at Mishimoto have also included a sight glass to allow for easy checking and filling to proper hot and cold coolant levels.

Better looks. The wrinkle black aluminium expansion tank provides a unique and custom look to your engine bay. Unlike the plastic coolant expansion tank, the tank will not yellow, degrade, leak, and crack over time.
