The GR Yaris's turbocharged three-cylinder is a genuine engineering marvel, but like any turbocharged engine, its performance is directly tied to how effectively the charge air is cooled before reaching the engine. Repeated hard pulls, spirited driving, or simply hot ambient conditions can push the factory intercooler past its comfortable operating range, raising intake air temperatures and costing you the performance the engine is genuinely capable of.
do88's replacement is built from full aluminium construction with continuous welds, delivering real cooling capacity and airflow improvements over the factory unit. A larger core increases both surface area and total volume, giving the charge air more time and more contact area to shed heat before it reaches the throttle body, translating into consistently cooler, denser air and more reliable performance run after run, not just on the first hard pull of the day.
Works with: OEM mounting points. Comes complete with mounting hardware and installation instructions.
