OIL COOLER KIT BLACK For GR YARIS
Stable Oil Temperature Control for High-Output and Circuit Driving!
Renewed Design – Compatible with GR Yaris GEN1 / GEN2


■Features
- To support the sub-radiator adopted on GEN2 models and DAT-equipped vehicles, the oil line routing has been revised, and a newly designed filter mount has been developed.
- When used in combination with the factory water-cooled oil cooler, the system effectively suppresses oil temperature rise even during continuous spirited or circuit driving, ensuring stable and efficient oil temperature control.
- A turn-flow type core is employed, delivering high cooling performance despite a limited core surface area.
- The vehicle-specific core design efficiently utilizes the front bumper opening, minimizing any impact on engine coolant temperature.
- Optimized oil line layout enables compatibility with GEN2 models (MT / DAT) while also allowing installation on GEN1 vehicles.
