APR's Engineers took a multi-step approach to optimizing the hoses to minimize boost leaks, reduce turbulence and other performance degradations. Four-ply silicone was utilized as it provides the thickness and strength characteristics necessary to support boost levels far beyond the engine's capabilities. A Fluorosilicone internal lining was added to ensure the hoses do not rapidly deteriorate over time when exposed to oil and gasoline from the PCV and EVAP systems. The included stainless-steel Clampco T-bolt clamps prevent the hoses from coming loose under heavy pressure and under high temperatures, silicone adheres to its mating surface, further minimizing leaks and hose slippage. APR's EZ-Flow stepped design creates a smooth airflow path, reducing turbulence over non-stepped designs. Finally, silicone provides better heat resistance over rubber, extending the life of the product and ultimate. The APR Boost Hose System is a comprehensive, direct replacement upgrade, to the factory rubber hoses found in the charge piping system. The system includes a multitude of enhancements designed for maximum performance, longevity and insurance against power robbing boost leaks. The system is sold both as a complete kit, and individually, and is fully compatible with the OEM and upgraded APR Intercooler system, OEM throttle body and all OEM turbochargers.. Multi-ply silicone outer construction: Pressure tested far beyond the engine’s capabilities, the system maintains performance under extreme conditions and increases burst resistance as well as mating surface adhesion compared to rubber..

Fluorosilicone interior surface: A Fluorosilicone coating on the interior surface greatly resists oil and gasoline permeation providing an extra layer of protection against deterioration of the hoses.. Additional quality control: APR take quality seriously. Each hose is fully tested before it leaves our doors to ensure fitment and our EZ-Flow design is perfectly matched!. APR EZ-Flow design: APR’s EZ-Flow stepped design provides maximum flow for maximum performance through a smooth, port matched transition from hose to connection surface.. Clampco T-bolt clamps: Stainless steel T-bolt clamps. Diminishes the risk of boost leaks with increased connection strength and decreased hose slippage..
