APR aprMS100115 MQB Complete Boost Hose Kit

APR is pleased to present the ultimate boost hose upgrade for MQB platform vehicles with the 1.8T and 2.0T engines!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.This system includes the turbo outlet hose, throttle body hose, and both intercooler hoses.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 Fits 2015-2020 Audi A3/A3 Quattro/S3 - 2019-2024 Audi Q3 - 2016-2023 Audi TT/TTS - 2019-2021 VW Arteon - 2015-2018 VW Golf - 2017-2019 Golf AT - 2015-2019 VW Golf R/Golf Sportwagen - 2015-2021 VW Intercooler hoses replace factory part 5Q0145832 & 5Q0145834. Throttle body hose replaces factory part 5Q0145838. Turbo outlet hose replaces factory part 5Q0145828. The turbo outlet pipe does not fit vehicles with the 7 speed DQ381 transmission.

• 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.
• Direct OEM replacement: Compatible with OEM/APR Intercooler, OEM Throttle body and all OEM turbochargers.

Brief Description: The APR aprMS100115 Boost Hose System is a direct-replacement upgrade for the factory rubber charge-piping hoses on select MQB-platform vehicles with 1.8T and 2.0T engines. The complete kit includes the turbo outlet hose, throttle body hose, and both intercooler hoses, providing a comprehensive solution designed to help minimize boost leaks, reduce airflow turbulence, and improve durability under demanding conditions.

Key Features & Performance Benefits: Four-ply silicone construction provides increased strength, burst resistance, heat resistance, and mating-surface adhesion compared with rubber. A fluorosilicone interior lining resists oil and gasoline permeation from the PCV and EVAP systems. APR EZ-Flow stepped transitions create a smooth, port-matched airflow path to reduce turbulence. Stainless-steel Clampco T-bolt clamps help increase connection strength and reduce hose slippage under pressure and elevated temperatures.
