The coolant hose is exposed to a harsh environment due to heat radiation from the engine and changes in cooling water pressure and temperature. Also, the genuine rubber hose expands due to the pressure of the cooling water, and the pressure is also lost. If this hose deteriorates, it may cause trouble . The J'S RACING coolant hose is made by SFS Performance of England. With a three-layer structure of Polyester Silicon, it is hard to cure even under severe temperature changes, and has excellent heat resistance and pressure resistance. Even in the case of sports driving that uses a lot of high engine speed, pressure loss is prevented even under load, ensuring high durability.
