Core Functions

• Optimized Air Transfer: Delivers compressed, high-temperature air from the turbocharger to the intercooler (for cooling) or engine intake with minimal airflow restriction. This ensures the engine receives a consistent supply of dense, oxygen-rich air—critical for maintaining turbocharged performance, fuel efficiency, and reducing emissions.
• Pressure & Heat Resistance: Withstands the high boost pressure generated by the turbocharger (up to 20 PSI) and extreme under-hood temperatures (ranging from -40°C to 150°C). The Kevlar reinforcement prevents the hose from expanding (ballooning) under pressure, while the NBR-CR rubber resists hardening, cracking, or melting from heat exposure.
• Leak Prevention: Features precision-molded connection ends that mate seamlessly with Volvo’s original turbocharger and intercooler ports. When paired with factory-style clamps (recommended for installation), it creates an airtight seal—avoiding compressed air leakage (which reduces turbo boost, engine power, and fuel efficiency) and preventing unfiltered air from entering the intake system.
• Contaminant Resistance: The NBR-CR rubber blend repels engine oil, coolant, and road debris—common contaminants that degrade generic hoses. This preserves the hose’s structural integrity and performance over time, extending its service life.

Compatible Vehicles
