APR 19-26 Audi Q3 MQB Complete 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.

Upgrade the charge-air system in your MQB-platform Audi or Volkswagen with the APR MS100115 Complete Boost Hose Kit. Designed as a direct replacement for the factory rubber hoses, this comprehensive system includes the turbo outlet hose, throttle body hose, and both intercooler hoses. It is compatible with the OEM or APR intercooler system, OEM throttle body, and OEM turbochargers, providing a reliable solution for reducing boost leaks and maintaining consistent performance.
APR engineered the system with a multi-layer silicone construction for increased strength, heat resistance, burst resistance, and long-term durability under demanding driving conditions. A fluorosilicone inner lining helps resist deterioration caused by oil and gasoline vapor from the PCV and EVAP systems. The APR EZ-Flow stepped design creates a smooth, port-matched transition between each hose and its connection point, helping reduce turbulence and support efficient airflow through the charge piping system.
Stainless-steel Clampco T-bolt clamps are included to provide secure connections and reduce the risk of hose slippage or boost leaks under elevated pressure and temperature. The kit replaces factory intercooler hose part numbers 5Q0145832 and 5Q0145834, throttle body hose part number 5Q0145838, and turbo outlet hose part number 5Q0145828. The turbo outlet hose is not compatible with vehicles equipped with the 7-speed DQ381 transmission.
This APR boost hose kit fits select 2015–2020 Audi A3 and A3 Quattro models, Audi S3, 2019–2024 Audi Q3, 2016–2023 Audi TT and TTS, 2019–2021 Volkswagen Arteon, 2015–2018 Volkswagen Golf, 2017–2019 Golf Alltrack, 2015–2019 Golf R and Golf SportWagen, and other compatible MQB vehicles with 1.8T or 2.0T engines. Verify vehicle configuration and transmission before installation.
