Mishimoto Ford Focus 3 RS / ST Coolant Expansion Tank

Add some additional reliability and engine bay styling with the Mishimoto Ford Focus 3 ST or RS expansion tank with internal baffles to prevent coolant starvation from overflow ports to engine. During high speed cornering, braking, and acceleration, the internal baffle reduces coolant sloshing. The engineers at Mishimoto have also included a sight glass to allow for proper hot and cold coolant levels.
