APR boost hose systems deliver the ultimate, direct-replacement upgrade for your factory hoses. Optimized to minimize boost leaks, reduce turbulence and other performance degradations, the 4-ply silicone provides thickness and strength characteristics necessary to support boost levels far beyond the engine's capabilities. The hoses are designed with APR's EZ-Flow stepped design for increased airflow—and they added a fluorosilicone internal lining to ensure the hoses do not rapidly deteriorate over time when exposed to oil and gasoline from PCV and EVAP systems. Stainless steel Clampco T-bolt clamps prevent the hoses from coming loose under heavy pressure; and under high temperatures, the silicone adheres to its mating surface, further minimizing leaks and hose slippage. APR boost hose systems are a great solution that directly replaces your factory rubber hoses for maximum performance, longevity, and insurance against power-robbing boost leaks.
