Audi A3 Intercooler Hoses - APR EZ-Flow 15-20. Purpose-built silicone boost hoses for the 2015-2020 Audi A3/S3 MQB 1.8T/2.0T, delivering a robust, direct-replacement solution for consistent charge-air flow.

APR’s EZ-Flow stepped design creates a smooth, port-matched transition that helps reduce turbulence and potential boost leaks compared to non-stepped designs. Four-ply silicone provides the rigidity to handle pressures far beyond stock requirements, while a Fluorosilicone internal lining resists oil and gasoline from PCV/EVAP systems for long-term durability. Under heat and pressure, silicone adheres to mating surfaces to further limit slippage. This conversion kit is intended for customers using the APR EFR7163 Turbocharger System and APR Turbo Outlet Pipe, and it reuses the stainless Clampco T-bolt clamps supplied with those kits.

Features

• EZ-Flow stepped, port-matched transitions for smoother airflow
