This is an intake hose developed by do88 to replace OEM intake hose. This is a stronger alternative to OEM hoses and in most cases with better airflow with its smooth inner layer! Our hoses have 4 PLY reinforcement and integrated steel wire to prevent the hose from collapsing under negative pressure. Another advantage of our hoses are the silicone material that withstands high temperature for long time. This makes our hosekits a terrific upgrade if your original hoses starts to crack from age or maybe you use your car in a way that the original hoses where not designed for. This hose kit is available in two different colors Blue / Black. There are no performance difference between the different colors, choose which color you think will be best for your car.
