The CV4 Radiator Hose Kit is a two-in-one package that brings style and performance. The quality of materials CV4 uses allows the inner diameter of the hoses to be much smoother then O.E.M. which increases radiator fluid flow. By increasing the flow through the hoses, the engine temperature will drop, therefore increasing horsepower. CV4 constructed the radiator hose kit with polyester reinforced silicone that provides better flow and durability then O.E.M. radiator hoses. Resists deterioration caused by UV and ozone toxins and will last much longer then O.E.M. hoses. The Y kit includes a CV4 hose that eliminates the connecting Y bracket on some models for improved flow. The CV4 radiator hose kit includes all the radiator hoses based on fitment.
