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 kit uses stainless-steel Clampco T-bolt clamps from your turbo kit and outlet pipe kit to 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 ultimately minimizing failure. The result is hose solution that directly replaces the factory rubber hoses and maintains performance under extreme conditions!. 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. This part is designed for customers who have an APR Turbo Pipe and need to adapt it to the APR DTR6054 Turbocharger System.. Fits Audi A3 15-20, A3 Quattro 15-20, Q3 19-24, S3 15-20, TT Quattro 16-23, TTS Quattro 16-23; VW Arteon 19-21, Golf 15-18, Golf Alltrack 17-19, Golf R 15-19, Golf SportWagen 15-19, GTI 15-21, Jetta 19-24. 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.. A Fluorosilicone coating on the interior surface greatly resists oil and gasoline permeation providing an extra layer of protection against deterioration of the hoses.. The system maintains performance under extreme conditions and increases both heat and burst resistance as well as mating surface adhesion compared to rubber.. Please Note: This is a conversion kit. It's only designed for customers who own the APR DTR6054 Turbocharger System and APR Turbo Outlet Pipe..
