Coolant hose is always exposed to a harsh environment due to heat radiation from the engine and changes in cooling water pressure and temperature. Moreover, the genuine rubber hose would expands due to the pressure of cooling water, and it would cause pressure lost. If the hose deteriorates, it may cause trouble.
The J'S RACING coolant hose is made by SFS Performance of England. It has a three-layer structure of Polyster Silicon, which is hard to cure even under severe temperature changes and has excellent heat resistance and pressure resistance. Even in the case of racing which uses a lot of high engine speed, pressure loss is prevented even under load, ensuring high durability.
The red colouring spice up the engine bay, and give prominence to your engine.
