The Ichiban Engineering IE Billet Racing Coolant Header Tank is a direct upgrade for the Toyota GR Yaris, designed to eliminate the weaknesses of the factory plastic tank while enhancing durability, reliability, and aesthetics for both street and track use.

Machined from premium 6061-T651 billet aluminum, this header tank is built to withstand significantly higher pressures and temperatures than the OEM unit — preventing the cracking, leaks, and coolant spray commonly experienced during aggressive driving or extended track sessions.
