However, through extensive road testing and durability evaluation, HKS has identified a key weakness: oil temperature tends to rise rapidly under high-load driving conditions.\u003c\/li\u003e\n\u003cli\u003eTo address this, we have refined the proven cooling layout from the FK8, utilizing the left front fender location while redesigning the system to match the characteristics of the FL5. Considering coolant temperature and A\/C performance, the oil cooler core has been positioned for maximum thermal efficiency.\u003c\/li\u003e\n\u003cli\u003eWind tunnel testing confirmed that airflow from the OEM front bumper alone is insufficient for optimal cooling. Therefore, a newly developed large air duct and dedicated air guide were designed specifically for the FL5 to deliver a strong supply of fresh air directly to the oil cooler core. This maximizes the performance potential of the system.\u003c\/li\u003e\n\u003cli\u003eNot only air intake but also evacuation of heated air was fully optimized. Through repeated aerodynamic testing, we ensured smooth discharge of air after it passes through the core, achieving the ideal airflow balance for the complete system. An outlet plate is included to protect the core from rock damage. As a result, oil temperature rise is significantly reduced even under demanding environments such as circuit driving, allowing the FL5 to maintain stable peak performance over extended periods.
