Developed in collaboration with Daiwa Racing Lab, the J's Racing Dual Cool system replaces the conventional "radiator + air-cooled oil cooler" setup with a radiator featuring a built-in water-cooled oil cooler. The result is improved cooling efficiency, a tidier engine bay, and a more compact, lightweight package.
Key Features
- Integrated water-cooled oil cooler design
- Controls oil temperature using stable coolant temperature
- More consistent cooling performance than traditional air-cooled systems
- Unaffected by variations in driving airflow
- Reduces oil warm-up time in cold conditions
- Maintains stable oil temperatures during aggressive summer driving and circuit use
- Louvered fins improve airflow and cooling performance
- Precisely angled louvred fins improve airflow and cooling performance
- Ultra-thin 0.25mm tubes (reduced from the standard 0.3mm) improve heat dissipation
- Lightweight integrated structure minimises frontend weight increase
- Compact design fits both radiator and oil cooler within the OEM mounting space
- Bolt-on installation with no modification required
Track Tested on the J's Racing FL5 demo car during mid-summer testing on international circuits, proving reliable cooling performance under sustained attack-lap conditions.
Ideal for customers seeking high-performance cooling, lightweight engineering for both street and track use.
