The factory piping connecting the turbo, intercooler, and throttle body on the GR Yaris carries the same limitation found on most OEM systems, it was designed around the factory intercooler's specific connection points and dimensions, and often includes tighter bends and narrower sections than ideal for maximum airflow. Once you upgrade to a larger, higher-capacity intercooler like do88's own unit, the OEM piping becomes a genuine mismatch, both in terms of physical fitment and airflow potential.
This pressure pipe kit is purpose-built specifically to connect to do88's own GR Yaris intercooler, ensuring every join in the system is properly sized and matched rather than adapted or forced to fit. The result is a smoother, more direct airflow path from turbo to throttle body, letting the rest of your cooling upgrade actually deliver its full potential rather than being bottlenecked by mismatched factory piping downstream.
Works with: do88's own Performance Intercooler for this platform (ICM-390-S) specifically. Not designed to connect to the factory OEM intercooler.
Why Choose These Pressure Pipes
Purpose-matched to do88's own GR Yaris intercooler connections
Smoother, more direct airflow path than adapting OEM piping
Ensures your intercooler upgrade delivers its full potential, not bottlenecked downstream
Genuine coordinated fitment, not a generic universal pipe kit
Compatibility
Toyota GR Yaris, with do88's Intercooler (ICM-390-S)
