Breather Hoses

The HPS Performance Silicone Breather + BPV Hoses is a high-performance replacement kit designed for the 2003-2006 Volkswagen Golf MK4 1.8T Turbo with a Late AWP Engine. This kit replaces OEM rubber breather and bypass valve hoses. It is constructed from high-temperature, 3-ply reinforced silicone with a fluoroelastomer inner lining for enhanced durability and resistance to extreme conditions.

The hoses are engineered to withstand prolonged exposure to high temperatures, oil, and fuel, with a maximum temperature rating of 350 °F. The fluoroelastomer lining resists degradation from gasoline, oils, and ethanol-based fuels while minimizing permeation and evaporation. Available in black, blue, and red, the kit ensures precise fitment with accurate bends and includes 100% stainless steel embossed clamps for secure installation.
