APR Intercooler Hoses replaces the factory rubber hoses and worm-gear clamps with high-quality multi-ply silicone hoses and strong Clampco T-bolt clamps. The interior of the hoses is smooth and lined with a fluorosilicone material designed to resist oil degradation and extend component life. EZ-Flow stepped lips within the hoses allow for a smooth connection from the hose to the pipe for uninterrupted airflow. We pay close attention to the airflow path and provide as few bends, and tight radius turns as possible. Furthermore, the hose material adheres to its mating surface under high temperatures to help create a stronger leak and slip-free connection. This results in a more reliable setup and increased performance through a smooth, strong, uninterrupted airflow path. These hoses are compatible with OEM and upgraded APR charge pipes and intercoolers.
