Product Description

The HPS Silicone Breather Hose Kit (part number 57-1934-BLK) is a high-performance replacement for the OEM rubber breather and bypass valve hoses in 2003-2006 Volkswagen Golf MK4 1.8T Turbo with a Late AWP Engine. Designed with 3-ply reinforced silicone and a fluoroelastomer inner lining, this kit provides exceptional durability and resistance to extreme conditions. The hoses are engineered to withstand prolonged exposure to high temperatures, oil, and fuel, ensuring reliable performance with a maximum temperature rating of 350 °F. Available in black, blue, and red, the kit offers precise fitment with correctly shaped bends and includes stainless steel embossed clamps for secure, leak-free installation.

Unlike standard silicone hoses, the fluoroelastomer lining resists degradation from gasoline, oils, and ethanol-based fuels while minimizing permeation and evaporation. This race-proven design is built for high-temperature service and prolonged under-hood heat exposure, making it ideal for demanding automotive applications. Whether as an upgrade or a replacement for OEM parts like breather hose 06A103221AN or boost pressure control line 06A145712C, the HPS Breather Hose Kit delivers superior quality and long-lasting performance.
