Vibrant Performance Aramid Reinforced Charge Air Cooler Transition Hose Coupler 4.00in x 3.00in ID – Universal
Vibrant Performance Aramid Reinforced Charge Air Cooler Hose Couplers connect 4.00 inch to 3.00 inch piping in custom turbo and supercharger intercooler systems on performance vehicles. These 3 inch long transition couplers compensate for minor misalignment and isolate vibration for smoother airflow. Stainless steel rings maintain shape under boost pressures while aramid layers support temperatures from -75 Degrees F to 392 Degrees F.
