The core thickness of the FK8 genuine radiator is 27mm, but the water temperature during sports driving quickly exceeds 100 ° C, making continuous driving difficult. Therefore, in order to continue to demonstrate the original performance of the K20C VTEC TURBO engine, SPOON pursued the optimum core thickness and fin shape, and repeated tests and trials. Generally, the thicker the core, the higher the cooling efficiency, but in fact, if it is too thick, it will be difficult for the wind to escape, and on the contrary, the efficiency will decrease and the weight of the radiator itself will increase. The aluminum radiator made by SPOON adopts a fin shape with high heat dissipation, and the core thickness is 36 mm, which greatly improves the cooling efficiency. A genuine fan shroud and condenser can be installed, and a PT1 / 8 boss for a retrofit sensor has also been added.
